Question

以下是我的通知代码： -

public void showNotification(String Name, String Rate, int Image_Source, int PandP, int Repeat) {

    RemoteViews remoteview = new RemoteViews(getPackageName(), R.layout.notification_layout);

    PendingIntent pi = PendingIntent.getActivity(this, 0, new Intent(this, SongsListActivity.class), 0);
    notification = new NotificationCompat.Builder(this)
            .setContent(remoteview)
            .setPriority(2)
            .setTicker(NameD.getText())
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(NameD.getText())
            .setContentText(RateD.getText())
            .setContentIntent(pi)
            .setAutoCancel(false)
            .setCustomBigContentView(remoteview)
            .build();

    notification.bigContentView = remoteview;
    remoteview.setImageViewResource(R.id.Repeat_N, Repeat);
    remoteview.setImageViewResource(R.id.P_and_P_N, PandP);
    remoteview.setTextViewText(R.id.Name_N, Name);
    remoteview.setTextViewText(R.id.Rate_N, Rate);
    remoteview.setImageViewResource(R.id.Image_N, Image_Source);
    notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(111111, notification);
}

这是我的xml通知： -

我的通知布局

现在如何向通知中的4个按钮添加操作，以便： -

a）暂停图像按钮暂停MediaPlayer媒体播放器，然后将其更改为播放。

b）下一个和上一个Imagebuttons调用方法mediaplayer（int i）

c）Repet Imagebutton调用方法changeRepeat（）

Answer 1

用于将侦听器添加到远程视图中

remoteViews.setOnClickPendingIntent(R.id.someView, pendingIntent);

Answer 2

您可以将remoteViews.setOnClickPendingIntent(R.id.someView, pendingIntent);与BroadCastReceiver结合使用并构建如下通知：

 private void showNotification(){private void showNotification(){
    Intent notificationIntent = new Intent(this, MainActivity.class);
    notificationIntent.addFlags(Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP);

    PendingIntent pendIntent = PendingIntent.getActivity
            (this, 1, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    // notification's layout
    RemoteViews mRemoteViews = new RemoteViews(getPackageName(), R.layout.custom_notification_small);
    mRemoteViews.setImageViewResource(R.id.notif_icon, R.mipmap.ic_launcher);
    mRemoteViews.setTextViewText(R.id.notif_title, "playMusic");
    mRemoteViews.setTextViewText(R.id.notif_content, "pauseMusic");

    Intent intentPlay = new Intent(this, MyReceiver.class);
    intentPlay.setAction(Constants.PLAY_ACTION);
    PendingIntent pIntentPlay = PendingIntent.getBroadcast
            (this, Constants.PENDING_PLAY_CODE, intentPlay, PendingIntent.FLAG_UPDATE_CURRENT);

    Intent intentPause = new Intent(this, MyReceiver.class);
    intentPause.setAction(Constants.PAUSE_ACTION);
    PendingIntent pIntentPause = PendingIntent.getBroadcast
            (this, Constants.PENDING_PAUSE_CODE, intentPause, PendingIntent.FLAG_UPDATE_CURRENT);

    mRemoteViews.setOnClickPendingIntent(R.id.notif_title, pIntentPlay);
    mRemoteViews.setOnClickPendingIntent(R.id.notif_content, pIntentPause);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
    mBuilder.setSmallIcon(R.drawable.icon_play)
            .setAutoCancel(false)
            .setOngoing(true)
            .setContentIntent(pendIntent)
            .setContent(mRemoteViews)
            .setTicker("musicStarted");

    startForeground(NOTIFY_ID, mBuilder.build());
}

在BroadCast接收器触发方法中你需要管理媒体播放器，在我的情况下我有一个绑定到MainActivity的服务，所以我通过接口连接了Main和Broadcast Receiver，当MainActivity的方法触发它时管理服务，服务管理它的MediaPlayer

如何在我的通知按钮中添加操作？
