广播接收器覆盖以前的通知

Question

我有这个接收器通知显示正常只是只显示最后一个通知其他被覆盖，如何避免它？

public class MyBroadCastReceiver  extends BroadcastReceiver {

    String TAG="onReceiveBroadcasst";

    public  MyBroadCastReceiver() {

    }

    Context context;
    @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(TAG, "onReceive: "+constants.notification);
        this.context=context;
        notification_maker("Running Late.","Hurry Up, Time to leave.",BitmapFactory.decodeResource(context.getResources(), R.drawable.late));
        notification_maker("Forecast.","Today's foreacast",BitmapFactory.decodeResource(context.getResources(), R.drawable.late));
        notification_maker("Notification.","Hurry Up, Time to leave.",BitmapFactory.decodeResource(context.getResources(), R.drawable.late));

        city=new PrefManager(context).getStringPref("City",city);
    }


    @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
    public  void notification_maker(String Title,String notification,Bitmap bitmap) {
        Bitmap icon1 = BitmapFactory.decodeResource(context.getResources(), R.drawable.cloudy);
        NotificationCompat.BigPictureStyle bigPicture = new NotificationCompat.BigPictureStyle();
        bigPicture.bigPicture(icon1);

        ToneGenerator toneGenerator = new ToneGenerator(AudioManager.STREAM_NOTIFICATION, 100);
        toneGenerator.startTone(ToneGenerator.TONE_PROP_BEEP, 1000);
        Notification notif = new Notification.Builder(context)
                .setContentTitle(Title)
                .setContentText(notification)
                .setSmallIcon(R.drawable.cloudy)
                .setLargeIcon(bitmap)
                .setStyle(new Notification.BigTextStyle().bigText(notification)
                        )
                .build();
        NotificationManager notificationManager=(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(2,notif);
        Log.i(TAG, Title+"notification_maker: "+notification);
    }
}

以下代码只会显示最后一条通知，App-logs中有其他通知调用成功的记录，如何避免？

Answer 1

旧通知正在被覆盖，因为您对所有通知使用相同的 ID：

notificationManager.notify(2,notif);

使用不同的 ID 来区分通知（即不要对所有通知使用 2）

广播接收器覆盖以前的通知

Broadcast Receiver overwrites previous notifications

android
