我已经在Manifest.xml中授予权限访问权限，感谢您的帮助

当我在下面使用此代码时，我可以播放mp3，但我不知道如何添加到recycleview列表显示？如何将其改为arraylist

AssetFileDescriptor fd1 = expansionFile.getAssetFileDescriptor("oldsong.mp3");
MediaPlayer mediaPlayer = new MediaPlayer();
try {
    mediaPlayer.setDataSource( fd.getFileDescriptor(),
            fd.getStartOffset(),fd.getLength());
} catch (IOException e) {
    e.printStackTrace();
}
try {
    mediaPlayer.prepare();
} catch (IOException e) {
    e.printStackTrace();
}
mediaPlayer.start();
