Question

我正在尝试获取当前在音乐播放器中播放的歌曲的持续时间。我正在使用下面的代码，并且能够获取艺术家姓名，曲目名称和一些其他详细信息，但无法找到持续时间和已用时间。有没有其他方法可以找到它？

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    IntentFilter iF = new IntentFilter();
    iF.addAction("com.android.music.metachanged");
    iF.addAction("com.android.music.playstatechanged");
    iF.addAction("com.android.music.playbackcomplete");
    iF.addAction("com.android.music.queuechanged");

    iF.addAction("com.htc.music.metachanged");

    iF.addAction("net.jjc1138.android.scrobbler.action.MUSIC_STATUS");

    registerReceiver(mReceiver, iF);
}

private BroadcastReceiver mReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle extra = intent.getExtras();
        Log.v("yossi", extra.toString());

    }
};

你将通过使用以下意图来获得歌曲的持续时间。但是仅支持少数玩家。请试一试

duration    =intent.getLongExtra(MediaStore.Audio.AudioColumns.DURATION, 0);
duration    =intent.getLongExtra("duration", 0);
