问题描述
我想通过模拟耳机的音乐控制来控制通用的音乐播放（播放/暂停，跳过等）。有没有办法播出ACTION_MEDIA_BUTTON意图是什么？我试着用sendBroadcast（）的常规方法，但没有奏效。
I am trying to control universal music playback (play/pause, skip etc.) by emulating headset music controls. Is there a way to broadcast the ACTION_MEDIA_BUTTON intent? I tried the regular way with sendBroadcast() but it didn't work.
这可能吗？
推荐答案
试试这个
long eventtime = SystemClock.uptimeMillis();
Intent downIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null);
KeyEvent downEvent = new KeyEvent(eventtime, eventtime,
KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE, 0);
downIntent.putExtra(Intent.EXTRA_KEY_EVENT, downEvent);
sendOrderedBroadcast(downIntent, null);
Intent upIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null);
KeyEvent upEvent = new KeyEvent(eventtime, eventtime,
KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE, 0);
upIntent.putExtra(Intent.EXTRA_KEY_EVENT, upEvent);
sendOrderedBroadcast(upIntent, null);
