[英]How to stop android notification from repeating itself
I'm trying to push a notification whenever battery status is below 5% but I want it once only.我试图在电池电量低于 5% 时推送通知,但我只想要一次。 With below code it's keep on repeating unless battery level gets out of condition.使用下面的代码,它会不断重复,除非电池电量状况不佳。
else if((level<=5)&(level>0)){
batteryState.setImageResource(R.drawable.ic_batterylow);
Notification notificationobject=new NotificationCompat.Builder(MainActivity.this,Notifications.CHANNEL_1_ID)
.setSmallIcon(R.drawable.ic_stat_name)
.setContentTitle("Battery Warning")
.setContentText("Your battery is low, please plugin the charger.")
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.build();
mNotificationManagerCompatObject.notify(1,notificationobject);
}
You can use a variable to check if you have called this method already or not :你可以使用一个变量来检查你是否已经调用过这个方法:
boolean isCalled = false;
else if((level<=5)&(level>0)){
//if you did not called your method once
if(isCalled == false){
//make sure that this will only get called once
isCalled = true;
batteryState.setImageResource(R.drawable.ic_batterylow);
Notification notificationobject=new NotificationCompat.Builder(MainActivity.this,Notifications.CHANNEL_1_ID)
.setSmallIcon(R.drawable.ic_stat_name)
.setContentTitle("Battery Warning")
.setContentText("Your battery is low, please plugin the charger.")
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.build();
mNotificationManagerCompatObject.notify(1,notificationobject);
}
}
