我试着花时间System.currentTimeMillis(),而不是用户按下媒体按钮.但回调是在媒体按钮再次上升时执行的action == KeyEvent.ACTION_UP.

我不想在我的解决方案中使用BroadcastReceiver.

这是我的代码:

    MediaSession audioSession = new MediaSession(getApplicationContext(), "TAG");
    audioSession.setCallback(new MediaSession.Callback() {

        @Override
        public boolean onMediaButtonEvent(final Intent mediaButtonIntent) {
            String intentAction = mediaButtonIntent.getAction();

            if (Intent.ACTION_MEDIA_BUTTON.equals(intentAction))
            {
                KeyEvent event = (KeyEvent)mediaButtonIntent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
                if (event != null)
                {
                    int action = event.getAction();
                    if (action == KeyEvent.ACTION_DOWN) {
                        long stopTimeOfGame_millis = System.currentTimeMillis();
                        UtilsRG.info("time stopped: " +stopTimeOfGame_millis);

                    }
                    if (action == KeyEvent.ACTION_UP) {
                         long test = System.currentTimeMillis();
                         UtilsRG.info("time stopped up: " +test);

                    }
                }

            }
            return super.onMediaButtonEvent(mediaButtonIntent);
        }



    }); …
