Bagaimana cara mengembangkan keyboard lunak untuk Android? [Tutup]

110

Saya ingin bermain-main dengan beberapa ide dan mengembangkan keyboard lunak untuk Android untuk menggantikan yang default.

Apakah ada informasi umum tentang pengembangan keyboard lunak untuk Android di luar sana? Adakah praktik atau pedoman terbaik?
Dapatkah saya melakukan hampir semua hal yang dapat saya lakukan dengan aplikasi Android biasa dengan aplikasi keyboard saya?
Dapatkah saya melakukan koneksi HTTP untuk menyinkronkan data keyboard dengan cloud DB dan telepon lain yang saya miliki?
Dapatkah saya membuka jendela / layar lain dengan menekan tombol, misalnya untuk menampilkan antarmuka input ubahsuaian yang berbeda dengan QWERTY biasa. Jika tidak berhasil, dapatkah saya menggunakan dialog pop-up?

Beberapa tips:

Baca tutorial ini: Membuat Metode Masukan
klon repo ini: LatinIME

Tentang pertanyaan Anda:

InputMethod pada dasarnya adalah Android Service, jadi ya, Anda dapat melakukan HTTP dan semua hal yang dapat Anda lakukan di file Service.

Anda dapat membuka Activitiesdan dialog dari InputMethod. Sekali lagi, ini hanya a Service.

Saya telah mengembangkan IME, jadi tanyakan lagi jika Anda mengalami masalah.

Hei, saya baru saja menemukan posting ini. Saya bertanya-tanya bagaimana cara membuat keyboard LatinIME. Saya mengkloning repo tetapi ketika saya mencoba membangun bagian java tampaknya mengeluh tentang bagian asli, dan saya tidak tahu cara mendapatkan ndk untuk membangun bagian yang benar. Ada tips?

Saya punya satu masalah tentang keyboard. Saya telah menambahkan metode input sesuai langkah-langkah yang diberikan di atas, meskipun opsi keyboard khusus saya ditampilkan dalam opsi pengaturan dengan keyboard bawaan, tetapi sebenarnya ketika saya memilih keyboard kustom saya untuk mengganti keyboard bawaan aplikasi saya di menabrak. Apakah Anda tahu di mana saya salah?

tautan ke repo LatinIME sepertinya tidak aktif

tautan ke repo LatinIME sepertinya turun @Bruce

@Macarse Saya telah menindaklanjuti dengan tutorial yang disebutkan dan saya terjebak dalam mengubah ukuran ketinggian keyboard. Ada petunjuk arah?

Buat Papan Kunci Kustom untuk EditText Sendiri

Unduh Seluruh Kode

Dalam posting ini saya Membuat Keyboard Sederhana yang berisi beberapa tombol khusus seperti (tombol Prancis) dan didukung huruf kapital dan huruf kecil dan tombol Angka dan beberapa Simbol.

Saya telah mengembangkan keyboard khusus dan kode saya sama seperti yang diposting di atas, ketika saya membuat apk, itu berjalan dengan sukses di perangkat Android apa pun (karena berfungsi sebagai aplikasi pengguna). Tetapi masalah datang ketika saya perlu menambahkan aplikasi saya sebagai aplikasi sistem (untuk itu saya menggunakan metode input) di perangkat apa pun dengan mengganti keyboard yang ada saat ini, itu menunjukkan nama keyboard saya di pengaturan, tetapi ketika saya memilih keyboard saya itu memberi saya kesalahan seperti "Sayangnya, papan MyKey telah berhenti". Ada yang tahu tentang ini ??? .....

Tempat yang baik untuk memulai adalah aplikasi contoh yang disediakan di dokumen pengembang .

Pedoman akan membuatnya dapat digunakan semaksimal mungkin. Lihatlah yang lain yang tersedia di pasar untuk melihat apa yang harus Anda tuju
Ya, layanan dapat melakukan banyak hal, termasuk internet; asalkan Anda telah meminta izin tersebut
Anda dapat membuka aktivitas dan melakukan apa pun yang Anda suka jika Anda mengalami masalah saat melakukan beberapa hal di keyboard. Misalnya keyboard HTC memiliki tombol untuk membuka aktivitas pengaturan, dan tombol lainnya untuk membuka dialog untuk mengubah bahasa.

Lihat IME lain untuk melihat apa yang seharusnya Anda tuju. Beberapa (seperti yang resmi) adalah open source.

pertama-tama Anda harus mendefinisikan file .xml dan membuat UI keyboard di dalamnya:

<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
android:keyWidth="12.50%p"
android:keyHeight="7%p">
<!--
android:horizontalGap="0.50%p"
android:verticalGap="0.50%p"
NOTE When we add a horizontalGap in pixels, this interferes with keyWidth in percentages adding up to 100%
NOTE When we have a horizontalGap (on Keyboard level) of 0, this make the horizontalGap (on Key level) to move from after the key to before the key... (I consider this a bug) 
-->
<Row>
    <Key android:codes="-5" android:keyLabel="remove"  android:keyEdgeFlags="left" />
    <Key android:codes="48"    android:keyLabel="0" />
    <Key android:codes="55006" android:keyLabel="clear" />
</Row>
<Row>
    <Key android:codes="49"    android:keyLabel="1"  android:keyEdgeFlags="left" />
    <Key android:codes="50"    android:keyLabel="2" />
    <Key android:codes="51"    android:keyLabel="3" />
</Row>
<Row>
    <Key android:codes="52"    android:keyLabel="4"  android:keyEdgeFlags="left" />
    <Key android:codes="53"    android:keyLabel="5" />
    <Key android:codes="54"    android:keyLabel="6" />
</Row>

<Row>
    <Key android:codes="55"    android:keyLabel="7"  android:keyEdgeFlags="left" />
    <Key android:codes="56"    android:keyLabel="8" />
    <Key android:codes="57"    android:keyLabel="9" />
</Row>

Dalam contoh ini Anda memiliki 4 baris dan di setiap baris Anda memiliki 3 kunci. Anda juga dapat meletakkan ikon di setiap tombol yang Anda inginkan.

Kemudian Anda harus menambahkan tag xml di UI aktivitas Anda seperti ini:

<android.inputmethodservice.KeyboardView
        android:id="@+id/keyboardview1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/white"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:visibility="visible" />

Juga di file aktivitas .java Anda, Anda harus menentukan keyboard dan menetapkannya ke EditText:

CustomKeyboard mCustomKeyboard1 = new CustomKeyboard(this,
            R.id.keyboardview1, R.xml.horizontal_keyboard);
    mCustomKeyboard1.registerEditText(R.id.inputSearch);

Kode ini menambahkan inputSearch (yang merupakan EditText) ke keyboard Anda.
