android - 如何在服务中放置一个 onclick 监听器

Question

我试图将此 onClick 监听器放在服务内部，以在服务内部的自定义 xml View 中注册来自 button 的点击一个通知栏。但是 onClickListener 得到编译器错误。有谁知道为什么会出现编译错误？

   RemoteViews remoteviews = new RemoteViews("com.example.test", R.layout.custom_notifications);

     NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(AudioService.this)
               .setContent(remoteviews)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("My notification")
                .setContentText("Hello World!")
                .setOngoing(true);



     remoteviews.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {

        Toast.makeText(AudioViewer.this, "play button was clicked", Toast.LENGTH_LONG).show();
            }
        });

编译器报错如下图所示:

您需要改用 setOnClickPendingIntent。 RemoteViews 类没有定义 setOnClickListener 方法。

你需要做这样的事情:

this.registerReceiver(new BroadcastReceiver() {
                @Override
                public void onReceive(Context context, Intent intent) {
                    Toast.makeText(AudioViewer.this,
                        "play button was clicked", Toast.LENGTH_LONG).show();
                }
            }, new IntentFilter("MyRemoteViewsBroadcast"));
PendingIntent pi = PendingIntent.getBroadcast(this, 0,
                       new Intent("MyRemoteViewsBroadcast"), 0);
remoteviews.setOnClickPendingIntent(R.layout.custom_notifications, pi);
