Question

我有一个Android应用程序。我希望在特定时间发出警报让我们说10:30 AM＆amp;晚上7点30分，我每天都重复搜索，但没有任何工作＆gt; \ n 我试过这段代码：

//var
public int AM_IS_ON = 1288, PM_IS_ON = 98760, am_hr, pm_hr;
private String am;
private AlarmManager alarmManager;
private SharedPreferences sharedPrefs;
private PendingIntent pendingIntent;
//////after OnCreate() Method//////
sharedPrefs = PreferenceManager.getDefaultSharedPreferences(this);
    am_hr = Integer.parseInt((sharedPrefs.getString("am_hr", "7")));
    pm_hr = Integer.parseInt((sharedPrefs.getString("pm_hr", "5")));
    boolean AM = sharedPrefs.getBoolean("isAM", true);
    boolean PM = sharedPrefs.getBoolean("isPM", true);
    boolean on_or_off = sharedPrefs.getBoolean("alarm_on_or_off", false);
    if (on_or_off) {
        if (AM) {
            SetAlarm(am_hr, AM_IS_ON, PM_IS_ON);

    } else {
        Toast.makeText(MainActivity.this, R.string.alarm_is_off, Toast.LENGTH_SHORT).show();
    }


public void SetAlarm(int hr, int am_uid, int pm_uid) {
    alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    am = "AM";
    Log.e("MyActivity", "Alarm On");
    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, hr);
    calendar.set(Calendar.MINUTE, 0);
    calendar.set(Calendar.SECOND, 0);
    Intent myIntent = new Intent(MainActivity.this, AlarmReceiver.class);
    if (am.equals("AM")) {
        am = "PM";
        Log.e("MyActivity", "AM On");
        calendar.set(Calendar.AM_PM, Calendar.AM);
        pendingIntent = PendingIntent.getBroadcast(MainActivity.this, am_uid, myIntent, Intent.FILL_IN_ACTION);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
    }
    if (am.equals("PM")) {
        Log.e("MyActivity", "PM On");
        calendar.set(Calendar.AM_PM, Calendar.PM);
        pendingIntent = PendingIntent.getBroadcast(MainActivity.this, pm_uid, myIntent, Intent.FILL_IN_ACTION);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
    }
}

＆安培;这是我的回忆者：

public class AlarmReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(final Context context, Intent intent) {
    //this will update the UI with message
    MainActivity inst = MainActivity.instance();
    //this will sound the alarm tone
    //this will sound the alarm once, if you wish to
    //raise alarm in loop continuously then use MediaPlayer and setLooping(true)
    Uri alarmUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
    if (alarmUri == null) {
        alarmUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    }
    Ringtone ringtone = RingtoneManager.getRingtone(context, alarmUri);
    ringtone.play();

    //this will send a notification message
    ComponentName comp = new ComponentName(context.getPackageName(),
            AlarmService.class.getName());
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
}

}

问题是当我打开MainActivity时SetAlarm（）方法＆gt;＆gt;这是为了PM＆amp;上午我想要的是在指定的时间内安排闹钟我该如何做到这一点？

Android使ALarmManager在特定时间运行＆amp;重播活动日
