Bagaimana mengelompokkan RadioButton dari LinearLayouts yang berbeda?

Saya bertanya-tanya apakah mungkin untuk mengelompokkan masing-masing RadioButtondalam satu RadioGroup pemeliharaan unik dengan struktur yang sama. Struktur saya terlihat seperti ini:

• LinearLayout_main
  • LinearLayout_1
    • RadioButton1
  • LinearLayout_2
    • RadioButton2
  • LinearLayout_3
    • RadioButton3

Seperti yang Anda lihat, sekarang masing RadioButton- masing adalah anak yang berbeda LinearLayout. Saya mencoba menggunakan struktur di bawah ini, tetapi tidak berhasil:

• Radiogroup
  • LinearLayout_main
    • LinearLayout_1
      • RadioButton1
    • LinearLayout_2
      • RadioButton2
    • LinearLayout_3
      • RadioButton3

Tampaknya orang-orang baik di Google / Android berasumsi bahwa saat Anda menggunakan RadioButtons, Anda tidak memerlukan fleksibilitas yang menyertai setiap aspek lain dari sistem UI / tata letak Android. Sederhananya: mereka tidak ingin Anda membuat tata letak bersarang dan tombol radio. Mendesah.

Jadi, Anda harus mengatasi masalah tersebut. Itu berarti Anda harus menerapkan tombol radio sendiri.

Ini tidak terlalu sulit. Di onCreate () Anda, setel RadioButtons Anda dengan onClick () mereka sendiri sehingga ketika diaktifkan, mereka mengaturChecked (true) dan melakukan yang sebaliknya untuk tombol lainnya. Sebagai contoh:

class FooActivity {

    RadioButton m_one, m_two, m_three;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        m_one = (RadioButton) findViewById(R.id.first_radio_button);
        m_two = (RadioButton) findViewById(R.id.second_radio_button);
        m_three = (RadioButton) findViewById(R.id.third_radio_button);

        m_one.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                m_one.setChecked(true);
                m_two.setChecked(false);
                m_three.setChecked(false);
            }
        });

        m_two.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                m_one.setChecked(false);
                m_two.setChecked(true);
                m_three.setChecked(false);
            }
        });

        m_three.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                m_one.setChecked(false);
                m_two.setChecked(false);
                m_three.setChecked(true);
            }
        });

        ...     
    } // onCreate() 

}

Ya, saya tahu - cara lama-sekolah. Tapi itu berhasil. Semoga berhasil!

Gunakan kelas yang saya buat ini. Ini akan menemukan semua anak yang dapat dicentang dalam hierarki Anda.

import java.util.ArrayList;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Checkable;
import android.widget.LinearLayout;

public class MyRadioGroup extends LinearLayout {

private ArrayList<View> mCheckables = new ArrayList<View>();

public MyRadioGroup(Context context) {
    super(context);
}

public MyRadioGroup(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

public MyRadioGroup(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

@Override
public void addView(View child, int index,
        android.view.ViewGroup.LayoutParams params) {
    super.addView(child, index, params);
    parseChild(child);
}

public void parseChild(final View child)
{
    if(child instanceof Checkable)
    {
        mCheckables.add(child);
        child.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                for(int i = 0; i < mCheckables.size();i++)
                {
                    Checkable view = (Checkable) mCheckables.get(i);
                    if(view == v)
                    {
                        ((Checkable)view).setChecked(true);
                    }
                    else
                    {
                        ((Checkable)view).setChecked(false);
                    }
                }
            }
        });
    }
    else if(child instanceof ViewGroup)
    {
        parseChildren((ViewGroup)child);
    }
}

public void parseChildren(final ViewGroup child)
{
    for (int i = 0; i < child.getChildCount();i++)
    {
        parseChild(child.getChildAt(i));
    }
}
}

Nah, saya menulis kelas sederhana ini.

Gunakan saja seperti ini:

// add any number of RadioButton resource IDs here
GRadioGroup gr = new GRadioGroup(this, 
    R.id.radioButton1, R.id.radioButton2, R.id.radioButton3);

atau

GRadioGroup gr = new GRadioGroup(rb1, rb2, rb3);
// where RadioButton rb1 = (RadioButton) findViewById(R.id.radioButton1);
// etc.

Anda dapat memanggilnya di onCreate () Aktivitas misalnya. Apa pun yang RadioButtonAnda klik, yang lain tidak akan dicentang. Juga, tidak masalah, jika beberapa RadioButtonsberada di dalam beberapa RadioGroup, atau tidak.

Inilah kelasnya:

package pl.infografnet.GClasses;

import java.util.ArrayList;
import java.util.List;

import android.view.View;
import android.view.View.OnClickListener;

     * making a group.
     * 
     * @param radios

     */
    public GRadioGroup(RadioButton... radios) {
        super();

        for (RadioButton rb : radios) {
            this.radios.add(rb);
            rb.setOnClickListener(onClick);
        }
    }

     */
    public GRadioGroup(View activity, int... radiosIDs) {
        super();

        for (int radioButtonID : radiosIDs) {
            RadioButton rb = (RadioButton)activity.findViewById(radioButtonID);
            if (rb != null) {
                this.radios.add(rb);
                rb.setOnClickListener(onClick);
            }
        }
    }

    /**
     * This occurs everytime when one of RadioButtons is clicked, 
     * and deselects all others in the group.
     */
    OnClickListener onClick = new OnClickListener() {

        @Override
        public void onClick(View v) {

            // let's deselect all radios in group
            for (RadioButton rb : radios) {

                ViewParent p = rb.getParent();
                if (p.getClass().equals(RadioGroup.class)) {
                    // if RadioButton belongs to RadioGroup, 
                    // then deselect all radios in it 
                    RadioGroup rg = (RadioGroup) p;
                    rg.clearCheck();
                } else {
                    // if RadioButton DOES NOT belong to RadioGroup, 
                    // just deselect it
                    rb.setChecked(false);
                }
            }

            // now let's select currently clicked RadioButton
            if (v.getClass().equals(RadioButton.class)) {
                RadioButton rb = (RadioButton) v;
                rb.setChecked(true);
            }

        }
    };

}

Inilah solusi saya berdasarkan solusi @lostdev dan implementasi RadioGroup. Ini adalah RadioGroup yang dimodifikasi untuk bekerja dengan RadioButtons (atau CompoundButtons lainnya) yang bersarang di dalam tata letak anak.

Anda dapat menggunakannya dalam tata letak Anda dengan cara yang sama seperti yang biasa Anda lakukan RadioGroupdengan pengecualian bahwa ini juga berfungsi dengan RadioButtontampilan bersarang :

<RecursiveRadioGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="16dp"
    android:layout_marginBottom="16dp"

    android:layout_marginRight="16dp"
    android:orientation="horizontal">

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:orientation="vertical">

        <RadioButton
            android:id="@+id/rbNotEnoughProfileInfo"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Not enough profile information"/>

        <RadioButton
            android:id="@+id/rbNotAGoodFit"

            android:layout_height="wrap_content"
            android:text="Dates no longer available"/>

    </LinearLayout>

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="vertical">

        <RadioButton
            android:id="@+id/rbOther"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Other"/>

        <android.support.v7.widget.AppCompatEditText

            android:textSize="15sp"
            android:gravity="top|left"
            android:hint="Tell us more"
            android:padding="16dp"
            android:background="@drawable/edit_text_multiline_background"/>
    </LinearLayout>

</RecursiveRadioGroup>

Solusi ini belum diposting jadi posting:

Langkah 0: Buat CompoundButton previousCheckedCompoundButton;sebagai variabel global.

Langkah 1: Buat OnCheckedChangedListeneruntuk tombol radio

CompoundButton.OnCheckedChangeListener onRadioButtonCheckedListener = new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (!isChecked) return;
            if (previousCheckedCompoundButton != null) {
                previousCheckedCompoundButton.setChecked(false);
                previousCheckedCompoundButton = buttonView;
            } else {
                previousCheckedCompoundButton = buttonView;
            }
        }
    };

Langkah 3: tambahkan pendengar ke semua tombol radio:

radioButton1.setOnCheckedChangeListener(onRadioButtonCheckedListener);
radioButton2.setOnCheckedChangeListener(onRadioButtonCheckedListener);
radioButton3.setOnCheckedChangeListener(onRadioButtonCheckedListener);
radioButton4.setOnCheckedChangeListener(onRadioButtonCheckedListener);

Itu dia!! kamu sudah selesai.

Sigh .. Sungguh disalahkan bahwa Android tidak memiliki fungsi dasar seperti itu.

Diadaptasi dari jawaban @ScottBiggs, berikut kemungkinan cara terpendek untuk melakukannya dengan Kotlin:

var currentSelected = button1
listOf<RadioButton>(
    button1, button2, button3, ...
).forEach {
    it.setOnClickListener { _ ->
        currentSelected.isChecked = false
        currentSelected = it
        currentSelected.isChecked = true
    }

Saya membuat dua metode ini untuk mengatasi masalah ini. Yang harus Anda lakukan adalah meneruskan ViewGroup di mana RadioButtons berada (bisa menjadi RadioGroup, LinearLayout, RelativeLayout, dll.) Dan menyetel kejadian OnClick secara eksklusif, yaitu, setiap kali salah satu RadioButtons yang merupakan anak dari ViewGroup ( di setiap tingkat bersarang) dipilih, yang lainnya tidak dipilih. Ini berfungsi dengan sebanyak mungkin tata letak bersarang yang Anda inginkan.

public class Utils {
    public static void setRadioExclusiveClick(ViewGroup parent) {
        final List<RadioButton> radios = getRadioButtons(parent);

        for (RadioButton radio: radios) {
            radio.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    RadioButton r = (RadioButton) v;
                    r.setChecked(true);
                    for (RadioButton r2:radios) {
                        if (r2.getId() != r.getId()) {
                            r2.setChecked(false);
                        }
                    }

                }
            });
        }
    }

    private static List<RadioButton> getRadioButtons(ViewGroup parent) {
        List<RadioButton> radios = new ArrayList<RadioButton>();
        for (int i=0;i < parent.getChildCount(); i++) {
            View v = parent.getChildAt(i);
            if (v instanceof RadioButton) {
                radios.add((RadioButton) v);
            } else if (v instanceof ViewGroup) {
                List<RadioButton> nestedRadios = getRadioButtons((ViewGroup) v);
                radios.addAll(nestedRadios);
            }
        }
        return radios;
    }
}

Penggunaan di dalam suatu aktivitas akan seperti ini:

ViewGroup parent = findViewById(R.id.radios_parent);
Utils.setRadioExclusiveClick(parent);

Saya telah menulis kelas grup radio saya sendiri yang memungkinkan untuk memuat tombol radio bersarang. Saksikan berikut ini. Jika Anda menemukan bug, beri tahu saya.

/**
 * This class is used to create a multiple-exclusion scope for a set of compound
 * buttons. Checking one compound button that belongs to a group unchecks any
 * previously checked compound button within the same group. Intially, all of
 * the compound buttons are unchecked. While it is not possible to uncheck a
 * particular compound button, the group can be cleared to remove the checked
 * state. Basically, this class extends functionality of
 * {@link android.widget.RadioGroup} because it doesn't require that compound
 * buttons are direct childs of the group. This means you can wrap compound
 * buttons with other views. <br>
 * <br>
 * 
 * <b>IMPORTATNT! Follow these instruction when using this class:</b><br>
 * 1. Each direct child of this group must contain one compound button or be
 * compound button itself.<br>
 * 2. Do not set any "on click" or "on checked changed" listeners for the childs
 * of this group.

Anda perlu melakukan dua hal:

1. Menggunakan mListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
2. Buat tampilan baris kustom Anda diterapkan Checkable.

Jadi saya pikir solusi yang lebih baik adalah menerapkan Checkable di dalam LinearLayout batin Anda: (terima kasih kepada daichan4649, dari tautannya, https://gist.github.com/daichan4649/5245378 , saya mengambil semua kode yang ditempel di bawah)

CheckableLayout.java

        return checked;
    }

    @Override
    public void setChecked(boolean checked) {
        if (this.checked != checked) {
            this.checked = checked;
            refreshDrawableState();

            for (int i = 0; i < getChildCount(); i++) {
                View child = getChildAt(i);
                if (child instanceof Checkable) {
                    ((Checkable) child).setChecked(checked);

Saya menghadapi masalah yang sama karena saya ingin menempatkan 4 tombol radio yang berbeda dalam dua linearlayout yang berbeda dan tata letak ini akan menjadi anak dari grup radio. Untuk mencapai perilaku keinginan di RadioGroup saya telah membebani fungsi addView

Inilah solusinya

public class AgentRadioGroup extends RadioGroup
{

    public AgentRadioGroup(Context context) {
        super(context);
    }

    public AgentRadioGroup(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onViewAdded(View child) {
        if( child instanceof ViewGroup)
        {
            ViewGroup viewGroup = (ViewGroup) child;
            for(int i=0; i<viewGroup.getChildCount(); i++)
            {
                View subChild = viewGroup.getChildAt(i);
                if( subChild instanceof ViewGroup )
                {
                    onViewAdded(subChild);
                }
                else
                {
                    if (subChild instanceof RadioButton) {
                        super.onViewAdded(subChild);
                    }
                }
            }
        }
        if (child instanceof RadioButton)
        {
            super.onViewAdded(child);
        }
    }
}

Tidak ada yang menghentikan Anda untuk mengimplementasikan struktur tata letak itu ( RadioGroupsebenarnya adalah subkelas dari LinearLayout) tetapi Anda tidak boleh melakukannya. Pertama-tama Anda membuat struktur dengan kedalaman 4 tingkat (menggunakan struktur tata letak lain Anda dapat mengoptimalkan ini) dan kedua, jika Anda RadioButtonsbukan anak langsung dari a RadioGroup, satu-satunya item yang dipilih dalam grup tidak akan berfungsi. Ini berarti bahwa jika Anda memilih Radiobuttondari tata letak itu dan kemudian memilih yang lain, RadioButtonAnda akan berakhir dengan dua yang RadioButtonsdipilih, bukan yang terakhir dipilih.

Jika Anda menjelaskan apa yang ingin Anda lakukan dalam tata letak itu mungkin saya dapat merekomendasikan Anda alternatif.

$ 0,02 saya berdasarkan @infografnet dan @lostdev (juga terima kasih @Neromancer atas saran Tombol Gabungan!)

public class AdvRadioGroup {
    public interface OnButtonCheckedListener {
        void onButtonChecked(CompoundButton button);
    }

    private final List<CompoundButton> buttons;
    private final View.OnClickListener onClick = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            setChecked((CompoundButton) v);
        }
    };

    private OnButtonCheckedListener listener;
    private CompoundButton lastChecked;


    public AdvRadioGroup(View view) {
        buttons = new ArrayList<>();
        parseView(view);
    }

    private void parseView(final View view) {
        if(view instanceof CompoundButton) {
            buttons.add((CompoundButton) view);
            view.setOnClickListener(onClick);
        } else if(view instanceof ViewGroup) {
            final ViewGroup group = (ViewGroup) view;
            for (int i = 0; i < group.getChildCount();i++) {
                parseView(group.getChildAt(i));
            }
        }
    }

    public List<CompoundButton> getButtons() { return buttons; }

    public CompoundButton getLastChecked() { return lastChecked; }

    public void setChecked(int index) { setChecked(buttons.get(index)); }

    public void setChecked(CompoundButton button) {
        if(button == lastChecked) return;

        for (CompoundButton btn : buttons) {
            btn.setChecked(false);
        }

        button.setChecked(true);

        lastChecked = button;

        if(listener != null) {
            listener.onButtonChecked(button);
        }
    }

    public void setOnButtonCheckedListener(OnButtonCheckedListener listener) { this.listener = listener; }
}

Penggunaan (dengan pendengar yang disertakan):

AdvRadioGroup group = new AdvRadioGroup(findViewById(R.id.YOUR_VIEW));
group.setOnButtonCheckedListener(new AdvRadioGroup.OnButtonCheckedListener() {
    @Override
    public void onButtonChecked(CompoundButton button) {
        // do fun stuff here!
    }
});

Bonus: Anda bisa mendapatkan tombol centang terakhir, daftar seluruh tombol, dan Anda dapat memeriksa tombol apa pun dengan indeks dengan ini!

    int currentCheckedRadioButton = 0;
    int[] myRadioButtons= new int[6];
    myRadioButtons[0] = R.id.first;
    myRadioButtons[1] = R.id.second;
    //..
    for (int radioButtonID : myRadioButtons) {
        findViewById(radioButtonID).setOnClickListener(
                    new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (currentCheckedRadioButton != 0)
                    ((RadioButton) findViewById(currentCheckedRadioButton)).setChecked(false);
                currentCheckedRadioButton = v.getId();

            }
        });
    }

Anda dapat menggunakan kode ekstensi RadioGroup sederhana ini. Jatuhkan tata letak / tampilan / gambar apa pun di dalamnya bersama dengan RadioButtons dan itu akan berfungsi.

Ini berisi callback pilihan yang mengembalikan RadioButton yang dipilih dengan indeksnya dan Anda dapat mengatur pilihan secara terprogram berdasarkan indeks atau id:

            selectionChangedListener.onSelectionChanged(rb, (int)rb.getTag());
        }
    }
}

Gunakan dalam tata letak Anda xml:

    <path.to.your.package.EnhancedRadioGroup>
       Layouts containing RadioButtons/Images/Views and other RadioButtons
    </path.to.your.package.EnhancedRadioGroup>

Untuk mendaftar ke panggilan balik:

        enhancedRadioGroupInstance.setOnSelectionChanged(new EnhancedRadioGroup.OnSelectionChangedListener() {
            @Override
            public void onSelectionChanged(RadioButton radioButton, int index) {

            }
        });

Meskipun ini mungkin topik yang lebih lama, saya ingin segera membagikan kode hacky sederhana yang saya tulis .. Ini bukan untuk semua orang dan dapat dilakukan dengan beberapa perbaikan juga ..

Situasi untuk menggunakan kode ini ??
Kode ini untuk orang-orang yang memiliki layout pertanyaan asli atau serupa, dalam kasus saya seperti di bawah ini. Ini secara pribadi untuk Dialog yang saya gunakan.

• LinLayout_Main
  • LinLayout_Row1
    • ImageView
    • Tombol radio
  • LinLayout_Row2
    • ImageView
    • Tombol radio
  • LinLayout_Row3
    • ImageView
    • Tombol radio

Apa kode itu sendiri ??
Kode ini akan menghitung setiap Anak dari "LinLayout_Main" dan untuk setiap anak yang merupakan "LinearLayout" kemudian akan menghitung Tampilan tersebut untuk RadioButtons.

Cukup itu akan melihat induk "LinLayout_Main" dan menemukan RadioButtons yang ada di setiap LinearLayouts Anak.

MyMethod_ShowDialog
Akan menampilkan dialog dengan file layout XML sambil juga mencarinya untuk menyetel "setOnClickListener" untuk setiap RadioButton yang ditemukannya

MyMethod_ClickRadio
Akan mengulang setiap RadioButton dengan cara yang sama seperti "MyMethod_ShowDialog" tetapi alih-alih menyetel "setOnClickListener", ia malah akan "setChecked (false)" untuk menghapus setiap RadioButton dan kemudian sebagai langkah terakhir akan "setChecked (false)" ke RadioButton yang yang disebut acara klik.

public void MyMethod_ShowDialog(final double tmpLat, final double tmpLng) {
        final Dialog dialog = new Dialog(actMain);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.layout_dialogXML);

        final LinearLayout tmpLayMain = (LinearLayout)dialog.findViewById(R.id.LinLayout_Main);
        if (tmpLayMain!=null) {
            // Perform look for each child of main LinearLayout
            int iChildCount1 = tmpLayMain.getChildCount();
            for (int iLoop1=0; iLoop1 < iChildCount1; iLoop1++){
                View tmpChild1 = tmpLayMain.getChildAt(iLoop1);
                if (tmpChild1 instanceof LinearLayout) {
                    // Perform look for each LinearLayout child of main LinearLayout
                    int iChildCount2 = ((LinearLayout) tmpChild1).getChildCount();
                    for (int iLoop2=0; iLoop2 < iChildCount2; iLoop2++){
                        View tmpChild2 = ((LinearLayout) tmpChild1).getChildAt(iLoop2);
                        if (tmpChild2 instanceof RadioButton) {
                            ((RadioButton) tmpChild2).setOnClickListener(new RadioButton.OnClickListener() {
                                public void onClick(View v) {
                                    MyMethod_ClickRadio(v, dialog);
                                }
                            });
                        }
                    }
                }
            }

            Button dialogButton = (Button)dialog.findViewById(R.id.LinLayout_Save);
            dialogButton.setOnClickListener(new Button.OnClickListener() {
                public void onClick(View v) {
                    dialog.dismiss();
                }
            });
        }
       dialog.show();
}


public void MyMethod_ClickRadio(View vRadio, final Dialog dDialog) {

        final LinearLayout tmpLayMain = (LinearLayout)dDialog.findViewById(R.id.LinLayout_Main);
        if (tmpLayMain!=null) {
            int iChildCount1 = tmpLayMain.getChildCount();
            for (int iLoop1=0; iLoop1 < iChildCount1; iLoop1++){
                View tmpChild1 = tmpLayMain.getChildAt(iLoop1);
                if (tmpChild1 instanceof LinearLayout) {
                    int iChildCount2 = ((LinearLayout) tmpChild1).getChildCount();
                    for (int iLoop2=0; iLoop2 < iChildCount2; iLoop2++){
                        View tmpChild2 = ((LinearLayout) tmpChild1).getChildAt(iLoop2);
                        if (tmpChild2 instanceof RadioButton) {
                            ((RadioButton) tmpChild2).setChecked(false);
                        }
                    }
                }
            }
        }

        ((RadioButton) vRadio).setChecked(true);
}

Mungkin ada bug, disalin dari proyek dan berganti nama menjadi Voids / XML / ID

Anda juga dapat menjalankan tipe loop yang sama untuk mengetahui item mana yang diperiksa

Ini adalah versi modifikasi dari solusi @ Infografnet. Sederhana dan mudah digunakan.

RadioGroupHelper group = new RadioGroupHelper(this,R.id.radioButton1,R.id.radioButton2); group.radioButtons.get(0).performClick(); //programmatically

Cukup salin dan tempel

package com.qamar4p.farmer.ui.custom;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.view.View;
import android.widget.CompoundButton;
import android.widget.RadioButton;

public class RadioGroupHelper {

    public List<CompoundButton> radioButtons = new ArrayList<>();

    public RadioGroupHelper(RadioButton... radios) {
        super();
        for (RadioButton rb : radios) {
            add(rb);
        }
    }

    public RadioGroupHelper(Activity activity, int... radiosIDs) {
        this(activity.findViewById(android.R.id.content),radiosIDs);
    }

    public RadioGroupHelper(View rootView, int... radiosIDs) {
        super();
        for (int radioButtonID : radiosIDs) {
            add((RadioButton)rootView.findViewById(radioButtonID));
        }
    }

    private void add(CompoundButton button){
        this.radioButtons.add(button);
        button.setOnClickListener(onClickListener);
    }

    View.OnClickListener onClickListener = v -> {
        for (CompoundButton rb : radioButtons) {
            if(rb != v) rb.setChecked(false);
        }
    };
}

Seperti yang ditunjukkan dalam jawaban, solusinya adalah peretasan khusus sederhana. Ini versi minimalis saya di Kotlin.

import android.widget.RadioButton

class SimpleRadioGroup(private val radioButtons: List<RadioButton>) {

    init {
        radioButtons.forEach {
            it.setOnClickListener { clickedButton ->
                radioButtons.forEach { it.isChecked = false }
                (clickedButton as RadioButton).isChecked = true
            }
        }
    }

    val checkedButton: RadioButton?
        get() = radioButtons.firstOrNull { it.isChecked }
}

maka Anda hanya perlu melakukan sesuatu seperti itu di onCreate aktivitas Anda atau onViewCreated fragmen:

SimpleRadioGroup(listOf(radio_button_1, radio_button_2, radio_button_3))

Ini adalah solusi saya di Kotlin untuk tata letak khusus dengan RadioButton di dalamnya.

tipInfoContainerFirst.radioButton.isChecked = true

var prevSelected = tipInfoContainerFirst.radioButton
prevSelected.isSelected = true

listOf<RadioButton>(
    tipInfoContainerFirst.radioButton,
    tipInfoContainerSecond.radioButton,
    tipInfoContainerThird.radioButton,
    tipInfoContainerForth.radioButton,
    tipInfoContainerCustom.radioButton
).forEach {
    it.setOnClickListener { _it ->
    if(!it.isSelected) {
        prevSelected.isChecked = false
        prevSelected.isSelected = false
        it.radioButton.isSelected = true
        prevSelected = it.radioButton
    }
  }
}

Saya mengalami masalah yang sama, saya harus menggunakan tombol Radio untuk gender dan semuanya dengan gambar dan teks jadi saya mencoba menyelesaikannya dengan cara berikut.

file xml:

<RadioGroup
       android:layout_marginTop="40dp"
       android:layout_marginEnd="23dp"
       android:id="@+id/rgGender"
       android:layout_width="match_parent"
       android:layout_below="@id/tvCustomer"
       android:orientation="horizontal"
       android:layout_height="wrap_content">

       <LinearLayout
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:orientation="vertical"
           android:gravity="center_horizontal"
           android:layout_weight="1">
       <RadioButton
           android:id="@+id/rbMale"
           android:layout_width="80dp"
           android:layout_height="60dp"
           android:background="@drawable/male_radio_btn_selector"
           android:button="@null"
           style="@style/RadioButton.Roboto.20sp"/>

           <TextView
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:text="Male"
               style="@style/TextView.RobotoLight.TxtGrey.18sp"
               android:layout_margin="0dp"
               android:textSize="@dimen/txtsize_20sp"/>
       </LinearLayout>
       <LinearLayout
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:orientation="vertical"
           android:gravity="center_horizontal"
           android:layout_weight="1">
       <RadioButton
           android:layout_weight="1"
           android:gravity="center"
           android:id="@+id/rbFemale"
           android:layout_width="80dp"
           android:layout_height="60dp"
           android:button="@null"
           android:background="@drawable/female_radio_btn_selector"
           style="@style/RadioButton.Roboto.20sp"
           android:textColor="@color/light_grey"/>
           <TextView
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:text="Female"
               android:layout_margin="0dp"
               style="@style/TextView.RobotoLight.TxtGrey.18sp"
               android:textSize="@dimen/txtsize_20sp"/>
       </LinearLayout>
       <LinearLayout
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:orientation="vertical"
           android:gravity="center_horizontal"
           android:layout_weight="1">
       <RadioButton
           android:layout_weight="1"
           android:gravity="center"
           android:id="@+id/rbOthers"
           android:layout_width="80dp"
           android:layout_height="60dp"
           android:button="@null"
           android:background="@drawable/other_gender_radio_btn_selector"
           style="@style/RadioButton.Roboto.20sp"/>
          <TextView
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="Other"
              android:layout_margin="0dp"
              style="@style/TextView.RobotoLight.TxtGrey.18sp"
              android:textSize="@dimen/txtsize_20sp"/>
      </LinearLayout>
   </RadioGroup>

Dalam file java: Saya mengatur setOnCheckedChangeListener pada semua 3 tombol radio dan metode override seperti yang disebutkan di bawah ini dan berfungsi dengan baik untuk saya.

@Override
    public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
   switch (compoundButton.getId()){
       case R.id.rbMale:
           if(rbMale.isChecked()){
               rbMale.setChecked(true);
               rbFemale.setChecked(false);
               rbOther.setChecked(false);
           }
           break;
       case R.id.rbFemale:
           if(rbFemale.isChecked()){
               rbMale.setChecked(false);
               rbFemale.setChecked(true);
               rbOther.setChecked(false);
           }
           break;
       case R.id.rbOthers:
           if(rbOther.isChecked()){
               rbMale.setChecked(false);
               rbFemale.setChecked(false);
               rbOther.setChecked(true);
           }
           break;

   }
    }

MixedCompoundButtonGroup melakukannya untuk Anda!

MixedCompoundButtonGroup intinya

fun setAll() {
    for (i in 0 until childCount) {
        val child = getChildAt(i)
        setCompoundButtonListener(child)
    }
}  


private fun setCompoundButtonListener(view: View?) {
    if (view == null) return
    if (view is CompoundButton) {
        view.setOnCheckedChangeListener(compoundButtonCheckedChangedListener)
    } else if (view is ViewGroup && view !is RadioGroup) { // NOT RadioGroup!
        for (i in 0 until view.childCount) {
            setCompoundButtonListener(view.getChildAt(i))
        }
    }
}

private fun initCompoundButtonListener() {
    compoundButtonCheckedChangedListener = CompoundButton.OnCheckedChangeListener { compoundButton, isChecked ->
        setChecked(compoundButton, isChecked)
    }
}

private fun setChecked(compoundButton: CompoundButton, isChecked: Boolean) {
    if (isChecked.not()) return
    if (currentCompoundButton != null) {
        currentCompoundButton!!.isChecked = false
        currentCompoundButton = compoundButton
    } else {
        currentCompoundButton = compoundButton
    }
    checkedChangedListener?.onCheckedChanged(currentCompoundButton!!)
}
