我的应用程序在通知栏中有一个显示电池电量的通知。通知有效,但是当单击首选项中的复选框并出现通知时,我尝试拉下通知栏并且它滞后。我不知道怎么做,但我认为这是因为通知每秒检查一次电池电量,但我不确定.. 我发布了代码:

@SuppressLint("NewApi")
    private void checkPref(Intent intent){ 
            this.registerReceiver(this.batteryInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
            SharedPreferences myPref = PreferenceManager.getDefaultSharedPreferences(MainActivity.this); 
            boolean pref_opt1 = myPref.getBoolean("firstDependent", false); 
            int level= intent.getIntExtra(BatteryManager.EXTRA_LEVEL,-1);
            if (pref_opt1){
                NotificationManager notifi = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
                 Notification notification = new Notification.Builder(getApplicationContext())
                 .setContentTitle("Battery Informations")
                 .setContentText("Battery level"+" "+level+"%")
                 .setSmallIcon(R.drawable.icon_small_not)
                 //.setLargeIcon(aBitmap)
                 .setTicker(level+"%")
                 .build();

                 notification.flags = Notification.FLAG_ONGOING_EVENT;
                 Intent i = new Intent(MainActivity.this, MainActivity.class); 
                 PendingIntent penInt = PendingIntent.getActivity(getApplicationContext(), 0 , i , 0);
                 notifi.notify(215,notification);
                } else {
                NotificationManager notifi = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
                notifi.cancel(215);
                }
        }

也许问题就是这个this.registerReceiver(this.batteryInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));。但我只知道当电池电量发生变化时更新通知的这种方式.. 有帮助吗?

检查显示通知的“if-case”代码是否重复执行。如果是这样,请尝试通过标志值将显示通知限制为一次,并在 notifi.cancel() 期间重置标志。
