android - 单击监听器上的通知 RemoteView

Question

所以，经过大量的摸索之后，我已经束手无策了。我的通知中有一个媒体播放器 RemoteViews，我希望能够访问播放、暂停、上一个和下一个按钮。

我知道 setOnClickPendingIntent() 将用于从通知进行通信。但是，我想知道这将如何工作。

是否可以让服务处理点击？

这个我试过了，没用。我试图让我的服务处理播放器的暂停和恢复:

rm = new RemoteViews(getApplicationContext().getPackageName(), R.layout.notif_media_player);

        Intent intent = new Intent(getApplicationContext(), MusicService.class);
        intent.putExtra(REQUEST_CODE, PAUSE);
        PendingIntent pending = PendingIntent.getService(getApplicationContext(), PAUSE, intent, 0);
        rm.setPendingIntentTemplate(R.id.pause, pending);

        Notification notif =  new NotificationCompat.Builder(getApplicationContext())
                                 .setOngoing(true)
                                 .setSmallIcon(R.drawable.ic_launcher)
                                 .setContent(rm)
                                 .build();

        NotificationManager mgr = (NotificationManager) getApplicationContext()
                                  .getSystemService(Context.NOTIFICATION_SERVICE);
        mgr.notify(NOTIFICATION_ID, notif);  

并且我的 IBinder 为空。如果那有所作为。

如何根据通知暂停和播放音乐？

基于 CommonsWare 的推荐:

        rm = new RemoteViews(getApplicationContext().getPackageName(), R.layout.notif_media_player);
        Intent pauseIntent = new Intent(getApplicationContext(), MusicService.class);
        Intent dismissIntent = new Intent(getApplicationContext(), MusicService.class);

        pauseIntent.putExtra(REQUEST_CODE, PAUSE);
        dismissIntent.putExtra(REQUEST_CODE, DISMISS);

        PendingIntent pause = PendingIntent.getService(getApplicationContext(), PAUSE, pauseIntent, 0);
        PendingIntent dismiss = PendingIntent.getService(getApplicationContext(), DISMISS, dismissIntent, 0);

        rm.setOnClickPendingIntent(R.id.pause, pause);
        rm.setOnClickPendingIntent(R.id.dismiss, dismiss);

        Notification notif =  new NotificationCompat.Builder(getApplicationContext())
                                 .setOngoing(true)
                                 .setSmallIcon(R.drawable.ic_launcher)
                                 .setContent(rm)
                                 .build();

        NotificationManager mgr = (NotificationManager) getApplicationContext()
                                  .getSystemService(Context.NOTIFICATION_SERVICE);
        mgr.notify(NOTIFICATION_ID, notif);
