Android:闹钟每 30 分钟播放一次，从 12:30 开始 [英] Android: Alarm to be play every 30 minutes and it start from 12:30

问题描述

这里我将使用闹钟服务每 30 分钟播放一次闹钟.现在我已经将它设置为从 Every start 开始每 10 秒播放一次.

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.

代码如下:

@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，我想从 12:30 开始闹钟，而不是从应用程序开始的时间开始，它应该每隔 30 分钟重复播放一次.比如 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

那么我必须对我的代码做哪些更改?

So what changes i have to do in my code ?
