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();
  }
}

            c.set(calendar.millisecond, 0);
            intent intent = new intent(test.this,alamrreceiver.class);
            pendingintent pi = pendingintent.getbroadcast(test.this, 0, intent, 0);
            alarmmanager am = (alarmmanager) getsystemservice(activity.alarm_service);
            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();

        am.cancel(pi);
        tv.settext("闹钟取消");
      }
    });
  }
