机器人 - 如何将告警设置成特定的日期 [英] Android - how to set an alarm to a specific date

问题描述

我已经看到了很多的教程和一直在努力2小时，现在，虽然事情仍然是错误的。我很紧张，现在:)我想设置一个报警，例如至16:25去了，但没有任何反应。我有这个code：

 日历cur_cal =新的GregorianCalendar（）;
    cur_cal.setTimeInMillis（System.currentTimeMillis的（））;

    日历CAL =新的GregorianCalendar（）;
    cal.add（Calendar.DAY_OF_YEAR，cur_cal.get（Calendar.DAY_OF_YEAR））;
    cal.set（Calendar.HOUR_OF_DAY，16）;
    cal.set（Calendar.MINUTE，25）;
    cal.set（Calendar.SECOND，0）;
    cal.set（Calendar.MILLISECOND，0）;

    alarmManager.set（AlarmManager.RTC_WAKEUP，cal.getTimeInMillis（），pendingIntent）;
 

我也试过这样的：

  cal.set（Calendar.AM_PM，cur_cal.get（Calendar.AM_PM））;
    cal.set（Calendar.HOUR，4）;
 

我的最终目标是使重复报警，如它应该每天熄灭在设定的时间。

更新2011年1月17日。仍然没有工作。我有这个code：

 日历CAL = Calendar.getInstance（）;
            cal.set（Calendar.YEAR，2011）;
            cal.set（Calendar.MONTH，Calendar.JANUARY）;
            cal.set（Calendar.DAY_OF_MONTH，17）;
            cal.set（Calendar.HOUR_OF_DAY，16）;
            cal.set（Calendar.MINUTE，58）;
         cal.set（Calendar.SECOND，0）;
          cal.set（Calendar.MILLISECOND，0）;
 

我也试过这样的：

  cal.set（Calendar.HOUR，4）;
 cal.set（Calendar.AM_PM，Calendar.PM）;
 

和这样的：

  cal.set（Calendar.HOUR_OF_DAY，4）;
            cal.set（Calendar.AM_PM，Calendar.PM）;
 

解决方案

        cal.clear（）;
        cal.set（2012,2,8,18,16）;

        AlarmManager alarmMgr =（AlarmManager）getSystemService（Context.ALARM_SERVICE）;
        意向意图=新的意图（这一点，AlarmReceiver.class）;
        PendingIntent pendingIntent = PendingIntent.getBroadcast（此，0，意图，0）;

I have seen a lot of tutorials and been trying for 2 hours now , though something is still wrong. I am very nervous now :) I want to set an alarm e.g. to 16:25 to go off, but nothing happens. I have this code:

   Calendar cur_cal = new GregorianCalendar();
    cur_cal.setTimeInMillis(System.currentTimeMillis());

    Calendar cal = new GregorianCalendar();
    cal.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR));
    cal.set(Calendar.HOUR_OF_DAY, 16);
    cal.set(Calendar.MINUTE, 25);
    cal.set(Calendar.SECOND, 0);
    cal.set(Calendar.MILLISECOND, 0);

    alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

I have also tried this:

 cal.set(Calendar.AM_PM, cur_cal.get(Calendar.AM_PM));
    cal.set(Calendar.HOUR, 4);

My final goal is to make it a repeating alarm, e.g. it should go off every day at the set time.

Update 01.17.2011. Still not working. I have this code:

           Calendar cal = Calendar.getInstance();
            cal.set(Calendar.YEAR, 2011);
            cal.set(Calendar.MONTH, Calendar.JANUARY); 
            cal.set(Calendar.DAY_OF_MONTH, 17);
            cal.set(Calendar.HOUR_OF_DAY, 16);
            cal.set(Calendar.MINUTE, 58);
         cal.set(Calendar.SECOND, 0);
          cal.set(Calendar.MILLISECOND, 0);

I have also tried this:

 cal.set(Calendar.HOUR, 4);
 cal.set(Calendar.AM_PM, Calendar.PM);

and this:

cal.set(Calendar.HOUR_OF_DAY, 4 );
            cal.set(Calendar.AM_PM, Calendar.PM);

解决方案

package your.pack.name;

import java.util.Calendar;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

public class AlarmActivity extends Activity {
    /** Called when the activity is first created. */

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Calendar cal = Calendar.getInstance();

        cal.setTimeInMillis(System.currentTimeMillis());
        cal.clear();
        cal.set(2012,2,8,18,16);

        AlarmManager alarmMgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(this, AlarmReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
       // cal.add(Calendar.SECOND, 5);
        alarmMgr.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);


    }
}
