安卓：报警是发挥每30分钟，从12:30开始 [英] Android: Alarm to be play every 30 minutes and it start from 12:30

问题描述

下面我将要使用的报警服务，在每30分钟打报警。现在我已经将它设置为从每一个每10秒启动，以发挥它。

Here i am going to use the alarm service to play the alarm at every 30 minutes. Right now i have set it to play it at every 10 second from the Every start.

下面是code：

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


    Intent myIntent = new Intent(SettingsActivity.this, MyAlarmService.class);
    pendingIntent = PendingIntent.getService(SettingsActivity.this, 0, myIntent, 0);

    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 10*1000, pendingIntent);

}

现在的问题是，我要开始从12:30不是从应用程序时开始报警，并应在反复外翻30分钟发挥。像1:00，1:30，2:00。 。 。等

Now the Problem is, I want to start the alarm from the 12:30 not from the time application start and it should repeatedly play at evert 30 minutes. like 1:00, 1:30, 2:00 . . . etc

所以，我有什么样的变化做我的code？

So what changes i have to do in my code ?
