在特定时间设置android警报

Question

我在特定时间设置闹钟,但每次打开应用程序时它都会打开,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);

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);

Answer 1

好吧,你需要将警报设置为下次5:59:00响铃.你可以通过获取当前时间来完成此操作,如果它在5:59:00之前设置警报,如果它在5:59:00之后再添加一天并设置警报.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));

    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

}

我想给你一个可构建的例子,但我还没有完全理解alarmmanager,所以这就是你所拥有的.基于ADK 15的eclipse 3.5.2构建
