推荐答案

获取从SD卡路径和歌曲名称。您可以从MediaStore歌曲的路径。

Get path and song Name from SD Card. You can find the path of the song from MediaStore.

媒体提供者包含的元数据可用于所有媒体内部和外部存储设备上。

The Media provider contains meta data for all available media on both internal and external storage devices.

private String[] STAR = { "*" };

public void ListAllSongs() 
    { 
        Cursor cursor;
        Uri allsongsuri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
        String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";

        if (isSdPresent()) {
            cursor = getContentResolver().query(allsongsuri, STAR, selection, null, null);

            if (cursor != null) {
                if (cursor.moveToFirst()) {
                    do {
                        String songname = cursor
                                .getString(cursor
                                        .getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
                        int song_id = cursor.getInt(cursor
                                .getColumnIndex(MediaStore.Audio.Media._ID));

                        String fullpath = cursor.getString(cursor
                                .getColumnIndex(MediaStore.Audio.Media.DATA));

                        String albumname = cursor.getString(cursor
                                .getColumnIndex(MediaStore.Audio.Media.ALBUM));

                    } while (cursor.moveToNext());
                }
                cursor.close();
            }
        }
    }


public static boolean isSdPresent() 
{
    return android.os.Environment.getExternalStorageState().equals(
                android.os.Environment.MEDIA_MOUNTED);
}
