android定时关机

Calendar calendar = Calendar.getInstance();

long nowTime = calendar.getTimeInMillis();//这是当前的时间

int hour = 你要设置的时间

int minutes = 你要设置的时间

Calendar myCal = Calendar.getInstance();

myCal.set(Calendar.HOUR_OF_DAY,hour);

myCal.set(Calendar.MINUTE,minutes);

long shutDownTime = myCal.getTimeInMillis();

Intent intent= new Intent();

intent.addAction();

PendingIntent pendingIntent =PendingIntent.getService(context,0,intent,0);

AlarmManager alarm =(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);

alarm.set(AlarmManager.RTC,shutDownTime -nowTime,pendingIntent);

下面是 service 。。。

接收到 Intent中的action 的话。。就启动。。

onStart(){

Intent intent = new Intent();

intent.setAction("android.intent.action.ACTION_SHUTDOWN");

sendBroadCast(intent);

}
