Android编程使用AlarmManager设置闹钟的方法

本文实例讲述了Android编程使用AlarmManager设置闹钟的方法。分享给大家供大家参考，具体如下：

package com.Aina.Android;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
/**

public class AlamrReceiver extends BroadcastReceiver {
 @Override
 public void onReceive(Context context, Intent intent) {
   // TODO Auto-generated method stub
   Toast.makeText(context, "闹钟时间到", Toast.LENGTH_LONG).show();
 }
}

           am.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pi);//设置闹钟
           am.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), (10*1000), pi);//重复设置
           tv.setText("设置的闹钟时间为："+hourOfDay+":"+minute);
         }
       },hour,minute,true).show();
     }
   });
