Question

我使用此代码暂停音乐播放器，它会暂停默认音乐播放器，但如果安装了其他音乐播放器，则无效。例如poweramp，realplayer等

以下是我用来暂停音乐的代码： -

AudioManager mAudioManager = (AudioManager)getSystemService(AUDIO_SERVICE);    

if (mAudioManager.isMusicActive()) 
{
  Intent i = new Intent("com.android.music.musicservicecommand");

  i.putExtra("command", "pause");
  ListenAndSleep.this.sendBroadcast(i);
}

Answer 1

简单地使用媒体按钮会不会更容易？大多数（如果不是全部）球员应该处理这些。

private static void sendMediaButton(Context context, int keyCode) {
    KeyEvent keyEvent = new KeyEvent(KeyEvent.ACTION_DOWN, keyCode);
    Intent intent = new Intent(Intent.ACTION_MEDIA_BUTTON);
    intent.putExtra(Intent.EXTRA_KEY_EVENT, keyEvent);
    context.sendOrderedBroadcast(intent, null);

    keyEvent = new KeyEvent(KeyEvent.ACTION_UP, keyCode);
    intent = new Intent(Intent.ACTION_MEDIA_BUTTON);
    intent.putExtra(Intent.EXTRA_KEY_EVENT, keyEvent);
    context.sendOrderedBroadcast(intent, null);
}

然后你可以使用：

sendMediaButton(getApplicationContext(), KeyEvent.KEYCODE_MEDIA_PAUSE);

您还可以发送停止键事件。以下是与相关密钥http://developer.android.com/reference/android/view/KeyEvent.html#KEYCODE_MEDIA_PAUSE

Answer 2

public static void pauseMusic() {

    KeyEvent ke = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PAUSE);
    Intent intent = new Intent(Intent.ACTION_MEDIA_BUTTON);
    intent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);

    // construct a PendingIntent for the media button and unregister it
    Intent mediaButtonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON);
    PendingIntent pi = PendingIntent.getBroadcast(AppContext.getContext(),
            0/*requestCode, ignored*/, mediaButtonIntent, 0/*flags*/);
    intent.putExtra(Intent.EXTRA_KEY_EVENT, ke);
    sendKeyEvent(pi, AppContext.getContext(), intent);

    ke = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PAUSE);
    intent.putExtra(Intent.EXTRA_KEY_EVENT, ke);
    sendKeyEvent(pi, AppContext.getContext(), intent);

    //        android.intent.action.MEDIA_BUTTON

}

private static void sendKeyEvent(PendingIntent pi, Context context, Intent intent) {
    try {
        pi.send(context, 0, intent);
    } catch (PendingIntent.CanceledException e) {
        Log.e(TAG, "Error sending media key down event:", e);
    }
}

如何在Android中暂停不同的音乐播放器？
