如何取消BroadcastReceiver的通知

Question

我的AlertReceiver类正在创建通知服务。如何取消创建的通知？

这是我的代码：

public class AlertReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
       createNotification(context,"Title","This is message body", "Alert");
    }
    public void createNotification(Context context,String msg,String msgText, String  msgAlert){
        PendingIntent notificIntent=PendingIntent.getActivity(context, 0,
                new Intent(context,MainActivity.class),0);
        NotificationCompat.Builder mBuilder=new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.my_image)
                .setContentTitle(msg)
                .setTicker(msgAlert)
                .setContentText(msgText);
        mBuilder.setContentIntent(notificIntent);
        mBuilder.setDefaults(NotificationCompat.DEFAULT_SOUND);
        mBuilder.setAutoCancel(true);
        NotificationManager mNotificationManager=
                (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(1,mBuilder.build());

    }
}

使用unregisterReceiver（BroadcastReceiver receiver）作为单独的函数来从您的类中注销Broadcast接收器类。

public void unRegisterAlertreceiver(){
     unregisterReceiver(this);
}
