每当我打开应用程序时，Android中的AlarmManager都会运行 [英] AlarmManager in android runs every time i open the app

问题描述

我有用于创建 alarmManager 主要活动的代码

I have a code for creating an alarmManager main activity

Calendar c = Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, 14);
c.set(Calendar.MINUTE, 41);
c.set(Calendar.SECOND, 0);
Intent intentAlarm = new Intent(this, AlarmReceiver.class);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC,c.getTimeInMillis(), pendingIntent.getBroadcast(this, 0, intentAlarm, pendingIntent.FLAG_ONE_SHOT));

在 AlarmReceive 类中，我有：

public void onReceive(Context context, Intent intent) {
    Toast.makeText(context, "Alarm Scheduled for Tommrrow", Toast.LENGTH_LONG).show();
    intent = new Intent(context, firstservice.class);
    context.startService(intent);
}

在使用中第一服务我做了一些手术。问题在于警报正在按时调用广播接收器，但是之后，当我打开应用程序时，它也会调用广播接收器，这意味着服务将再次运行。

In service firstservice I did some operation. The problem is that the alarm is calling the broadcast receiver on time but after that when I open the app it also call the broadcast receiver and this mean that the service is worked again.

推荐答案

我也遇到了这个问题。在几个小时之后，我可以指出此解决方案的问题。简而言之，我已经使用了意图附加功能来通知警报时间。

I also had this problem. After copple of hours, I could point out the problem with this solution. In brief I have used intent extras to notify the alarm time.

在manifest.xml中，注册接收者。

in the manifest.xml, register the receiver.

 <receiver android:name=".receivers.DayAlarmReceiver"/>

这是我设置警报管理器的方式

This is how I set the alarm manager

 public void setDayAlarm(Context context) {

    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.set(Calendar.HOUR_OF_DAY, 4);

    AlarmManager alarmMgr = (AlarmManager) getSystemService(ALARM_SERVICE);
    Intent alarmIntent = new Intent(context, DayAlarmReceiver.class);
    alarmIntent.putExtra("HOUR_OF_DAY", 4);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 5555, alarmIntent, 0);
    alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY, pendingIntent);
    Log.d("Set the day alarm");

}

这是我的DayAlarmReceiver类的OnReceive（）方法

This is the OnReceive() method of my DayAlarmReceiver class

@Override
public void onReceive(Context context, Intent intent) {
    int setHour = intent.getIntExtra("HOUR_OF_DAY", -1);
    Calendar rightNow = Calendar.getInstance();
    int currentHour = rightNow.get(Calendar.HOUR_OF_DAY);

    if(currentHour == setHour){
        Log.d("This is perfect, Trigger the alarm");
        showNotification(context, msg);
    }else{
       Log.d("This is perfect, Trigger the alarm");

    }

快乐编码:)
