通知 BroadcastReceiver 在 Activity 中不工作

Question

我有一个通知，当按下通知中的特定按钮时，我正在尝试 运行 activity 中的方法。我在 onCreate 中创建 broadcastReceiver:

    //broadcast receiver stuff
    broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            // Code to run
            if (intent.getAction().equals("stop")){
                StartButtonClick();
            }
        }
    };
    registerReceiver(broadcastReceiver, new IntentFilter("stop"));

然后我在同一个 activity 中创建通知（虽然不在 onCreate 中）：

private void ShowNotification(){
    //add intent for app to resume when notification is clicked
    PendingIntent reopenAppIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);

    //add intent for app to stop service when stop button in notification is clicked
    //this is the intent I am creating for the notification button
    Intent stopIntent = new Intent("stop");
    PendingIntent stopPendingIntent = PendingIntent.getService(this, 1, stopIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    //create notification
    NotificationCompat.Builder notification = new NotificationCompat.Builder(this, CHANNEL_1_ID)
            .setContentTitle("Messaging in progress")
            .setContentText("User is late")
            .setOngoing(true)
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setSmallIcon(R.drawable.ic_message)
            .setContentIntent(reopenAppIntent)
            .addAction(R.drawable.ic_message, "Stop", stopPendingIntent); //here I am adding the intent for the butt that I want to activate the broadcastReceiver
    notificationManager.notify(1, notification.build());
}

当我点击通知中的按钮时，没有任何反应。我什至在 broadcastReceiver 的 if 语句上设置了一个断点，按下按钮时什么也没有发生。

试试这个

PendingIntent stopPendingIntent = PendingIntent.getBroadcast(this, 1, stopIntent, PendingIntent.FLAG_UPDATE_CURRENT);

而不是

PendingIntent stopPendingIntent = PendingIntent.getService(this, 1, stopIntent, PendingIntent.FLAG_UPDATE_CURRENT);
