Cara mendapatkan jalur file lengkap dari URI

Question 1

Saya ingin mendapatkan jalur file lengkap, dari URI. URI bukanlah Gambar, tetapi ini file musik, tetapi jika saya melakukannya seperti Solusi MediaStore, URI tidak akan berfungsi jika pengguna aplikasi memilih misalnya Astro sebagai browser, bukan Pemutar Musik. Bagaimana cara mengatasi ini?

Question 2

Menggunakan:

String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));

atau

String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));

Question 3

Metode PathUtil hanya akan bekerja di bawah oreo dan jika oreo daripada kemungkinan akan crash karena di oreo kita tidak akan mendapatkan id tetapi seluruh jalur di data.getData () jadi yang perlu Anda lakukan hanyalah membuat file dari uri dan dapatkan jalurnya dari getPath () dan pisahkan. di bawah ini adalah kode yang berfungsi: -

Uri uri = data.getData(); 
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).

Kode di atas akan berfungsi di oreo dan jika di bawah oreo maka PathUtil akan berfungsi.

String filePath=PathUtil.getPath(context,yourURI);

Question 5

Coba ini.

public String getRealPathFromURI(Uri contentUri) 
{
     String[] proj = { MediaStore.Audio.Media.DATA };
     Cursor cursor = managedQuery(contentUri, proj, null, null, null);
     int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
     cursor.moveToFirst();
     return cursor.getString(column_index);
}

Question 6

Anda dapat menggunakan get File path dari berbagai versi SDk

Gunakan RealPathUtils untuk itu

public class RealPathUtils {

@SuppressLint("NewApi")
public static String getRealPathFromURI_API19(Context context, Uri uri){
    String filePath = "";
    String wholeID = DocumentsContract.getDocumentId(uri);

    // Split at colon, use second item in the array
    String id = wholeID.split(":")[1];

    String[] column = { MediaStore.Images.Media.DATA };

    // where id is equal to
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            column, sel, new String[]{ id }, null);

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }
    cursor.close();
    return filePath;
}


@SuppressLint("NewApi")
public static String getRealPathFromURI_API11to18(Context context, Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    String result = null;

    CursorLoader cursorLoader = new CursorLoader(
            context,
            contentUri, proj, null, null, null);
    Cursor cursor = cursorLoader.loadInBackground();

    if(cursor != null){
        int column_index =
                cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        result = cursor.getString(column_index);
    }
    return result;
}

public static String getRealPathFromURI_BelowAPI11(Context context, Uri contentUri){
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
    int column_index
            = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}
}

** Sekarang dapatkan Path file dari URI **

 String path = null;
                if (Build.VERSION.SDK_INT < 11)
                    path = RealPathUtils.getRealPathFromURI_BelowAPI11(MainActivity.this, uri);

                    // SDK >= 11 && SDK < 19
                else if (Build.VERSION.SDK_INT < 19)
                    path = RealPathUtils.getRealPathFromURI_API11to18(MainActivity.this, uri);

                    // SDK > 19 (Android 4.4)
                else
                    path = RealPathUtils.getRealPathFromURI_API19(MainActivity.this, uri);
                Log.d(TAG, "File Path: " + path);
                // Get the file instance
                 File file = new File(path);

Question 7

salah satu jawaban yang ada di halaman saat ini ( ini ), benar tetapi ada beberapa kesalahan. misalnya, ini tidak akan berfungsi pada perangkat dengan API 29+. Saya akan memperbarui kode di atas dan memposting versi barunya. Saya pikir posting ini harus ditandai sebagai jawaban akhir.

Question 12

Saya mengalami kesulitan mencoba mencari tahu ini di Xamarin. Dari saran di atas saya menemukan solusi ini.

private string getRealPathFromURI(Android.Net.Uri contentUri)
{
    string filename = "";
    string thepath = "";
    Android.Net.Uri filePathUri;
    ICursor cursor = this.ContentResolver.Query(contentUri, null, null, null, null);

    if (cursor.MoveToFirst())
    {
        int column_index = cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
        filePathUri = Android.Net.Uri.Parse(cursor.GetString(column_index));
        filename = filePathUri.LastPathSegment;
        thepath = filePathUri.Path;
    }

    return thepath;
}

Answer 1

Saya ingin mendapatkan jalur file lengkap, dari URI. URI bukanlah Gambar, tetapi ini file musik, tetapi jika saya melakukannya seperti Solusi MediaStore, URI tidak akan berfungsi jika pengguna aplikasi memilih misalnya Astro sebagai browser, bukan Pemutar Musik. Bagaimana cara mengatasi ini?

Answer 2

62

Menggunakan:

String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));

atau

String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));

Answer 8

Metode PathUtil hanya akan bekerja di bawah oreo dan jika oreo daripada kemungkinan akan crash karena di oreo kita tidak akan mendapatkan id tetapi seluruh jalur di data.getData () jadi yang perlu Anda lakukan hanyalah membuat file dari uri dan dapatkan jalurnya dari getPath () dan pisahkan. di bawah ini adalah kode yang berfungsi: -

Uri uri = data.getData(); 
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).

Kode di atas akan berfungsi di oreo dan jika di bawah oreo maka PathUtil akan berfungsi.

String filePath=PathUtil.getPath(context,yourURI);

Answer 25

Anda dapat menggunakan get File path dari berbagai versi SDk

Gunakan RealPathUtils untuk itu

public class RealPathUtils {

@SuppressLint("NewApi")
public static String getRealPathFromURI_API19(Context context, Uri uri){
    String filePath = "";
    String wholeID = DocumentsContract.getDocumentId(uri);

    // Split at colon, use second item in the array
    String id = wholeID.split(":")[1];

    String[] column = { MediaStore.Images.Media.DATA };

    // where id is equal to
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            column, sel, new String[]{ id }, null);

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }
    cursor.close();
    return filePath;
}


@SuppressLint("NewApi")
public static String getRealPathFromURI_API11to18(Context context, Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    String result = null;

    CursorLoader cursorLoader = new CursorLoader(
            context,
            contentUri, proj, null, null, null);
    Cursor cursor = cursorLoader.loadInBackground();

    if(cursor != null){
        int column_index =
                cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        result = cursor.getString(column_index);
    }
    return result;
}

public static String getRealPathFromURI_BelowAPI11(Context context, Uri contentUri){
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
    int column_index
            = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}
}

** Sekarang dapatkan Path file dari URI **

 String path = null;
                if (Build.VERSION.SDK_INT < 11)
                    path = RealPathUtils.getRealPathFromURI_BelowAPI11(MainActivity.this, uri);

                    // SDK >= 11 && SDK < 19
                else if (Build.VERSION.SDK_INT < 19)
                    path = RealPathUtils.getRealPathFromURI_API11to18(MainActivity.this, uri);

                    // SDK > 19 (Android 4.4)
                else
                    path = RealPathUtils.getRealPathFromURI_API19(MainActivity.this, uri);
                Log.d(TAG, "File Path: " + path);
                // Get the file instance
                 File file = new File(path);

Saya mengalami kesulitan mencoba mencari tahu ini di Xamarin. Dari saran di atas saya menemukan solusi ini.

private string getRealPathFromURI(Android.Net.Uri contentUri)
{
    string filename = "";
    string thepath = "";
    Android.Net.Uri filePathUri;
    ICursor cursor = this.ContentResolver.Query(contentUri, null, null, null, null);

    if (cursor.MoveToFirst())
    {
        int column_index = cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
        filePathUri = Android.Net.Uri.Parse(cursor.GetString(column_index));
        filename = filePathUri.LastPathSegment;
        thepath = filePathUri.Path;
    }

    return thepath;
