在特定时间设置android闹钟 [英] set android alarm at specific time

问题描述

我在特定的时间设置闹钟，但是每次打开应用程序，都会打开
这是我使用的代码：

  AlarmManager alarmManager =（AlarmManager）getSystemService（Context.ALARM_SERVICE）; 
 Intent intent = new Intent（this，AlarmReceiver.class）; 
 PendingIntent pendingIntent = PendingIntent.getBroadcast（this，0010000，intent，0）; 
 
日历时间= Calendar.getInstance（）; 
 time.set（Calendar.HOUR，5）; 
 time.set（Calendar.MINUTE，59）; 
 time.set（Calendar.SECOND，0）; 
 
 alarmManager.set（AlarmManager.RTC，time.getTimeInMillis（），pendingIntent）; 
  

解决方案

好的，你需要设置闹钟来响铃下一次是5:59:00。
通过获取当前时间，如果在5:59:00之前，设置闹钟，如果在5:59:00之后添加一天并设置闹钟，您可以这样做。这样做：

  import java.util.Calendar; 
 import java.util.Date 
 
 
 @Override 
 public void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 requestWindowFeature（Window.FEATURE_NO_TITLE）; 
 setContentView（new Panel（this））; 
 
日期dat = new Date（）; //初始化到现在
日历cal_alarm = Calendar.getInstance（）; 
日历cal_now = Calendar.getInstance（）; 
 cal_now.setTime（dat）; 
 cal_alarm.setTime（dat）; 
 cal_alarm.set（Calendar.HOUR_OF_DAY，5）; //设置闹钟时间
 cal_alarm.set（Calendar.MINUTE，59）; 
 cal_alarm.set（Calendar.SECOND，0）; 
 if（cal_alarm.before（cal_now））{//如果它在过去增加
 cal_alarm.add（Calendar.DATE，1）; 
} 
 //设置您的AlarmManager在这里
 
} 
  

我想给你一个可建立的例子，但是我并不完全了解闹钟，所以这就是你所拥有的。建立在日食3.5.2与ADK 15

i set the alarm at specific time but every time i open the application it will turn on this is the code i used :

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this,0010000,intent,0);

Calendar time = Calendar.getInstance();
time.set(Calendar.HOUR, 5);
time.set(Calendar.MINUTE, 59);
time.set(Calendar.SECOND, 0);

alarmManager.set(AlarmManager.RTC,time.getTimeInMillis(),pendingIntent);

解决方案

Alright, you need to set the alarm to ring the next time it is 5:59:00. You do this by getting the current time, if its before 5:59:00, set the alarm, if its after 5:59:00 then add a day and set the alarm. Do it like so:

import java.util.Calendar;
import java.util.Date;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(new Panel(this));

    Date dat  = new Date();//initializes to now
    Calendar cal_alarm = Calendar.getInstance();
    Calendar cal_now = Calendar.getInstance();
    cal_now.setTime(dat);
    cal_alarm.setTime(dat);
    cal_alarm.set(Calendar.HOUR_OF_DAY,5);//set the alarm time
    cal_alarm.set(Calendar.MINUTE, 59);
    cal_alarm.set(Calendar.SECOND,0);
    if(cal_alarm.before(cal_now)){//if its in the past increment
        cal_alarm.add(Calendar.DATE,1);
    }
    //SET YOUR AlarmManager here

}

I wanted to give you a buildable example, but i don't fully understand alarmmanager yet, so this is what you have. Built on eclipse 3.5.2 with ADK 15
