如何在android中每周安排警报？

Question

我想根据所需的天数E.g.安排一个闹钟。周日，周二，周四。我已经根据时间安排了它，但无法按周计算。

下面是代码：

private void StartScheduler(Context context) { 

     Calendar startTimmer = Calendar.getInstance(); 
     startTimmer.setTimeZone(TimeZone.getDefault());   
     startTimmer.set(Calendar.HOUR_OF_DAY,sHour); 
     startTimmer.set(Calendar.MINUTE,sMinute); 
     startTimmer.set(Calendar.SECOND,00); 

     AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);   
     Intent StartAlarmTime = new Intent(Schedule_details.this, MyAlaramStartReceiver.class);   
     PendingIntent pendingIntent1 = PendingIntent.getBroadcast(context, 0, StartAlarmTime, 0); 

     alarmManager.set(AlarmManager.RTC_WAKEUP, startTimmer.getTimeInMillis(),pendingIntent1);  
     Log.d("<<My-Start-Alarm>>", "ALARM Set To Start At: " + startTimmer.getTime().toLocaleString()); 
}

下面是答案：

public class MyReceiver extends BroadcastReceiver { 
DBAdapter mDba; 
SQLiteDatabase mDb; 
Ringtone rt; 
MediaPlayer mp; 
AlertDialog.Builder alertbox; 
Context ctx; 

@Override 
public void onReceive(Context context, Intent intent) { 

    DBHelper mDbh = new DBHelper(context, null, null, 1); 
    mDb = mDbh.getWritableDatabase(); 
    mDb.setLockingEnabled(true); 
    mDba = new DBAdapter(context); 
    mDba.open(); 
    Cursor cr = mDb.query("mReminderEntry", null, null, null, null, 
      null, null); 
    if (cr.equals(null)) { 
     System.out.println("No Data Found"); 
    } else { 
     Date d = new Date(); 
     Calendar calendar = Calendar.getInstance(); 
     int day = calendar.get(Calendar.DAY_OF_WEEK); 
     String today = null; 
     if (day == 2) { 
      today = "Monday"; 
     } else if (day == 3) { 
      today = "Tuesday"; 
     } else if (day == 4) { 
      today = "Wednesday"; 
     } else if (day == 5) { 
      today = "Thursday"; 
     } else if (day == 6) { 
      today = "Friday"; 
     } else if (day == 7) { 
      today = "Saturday"; 
     } else if (day == 1) { 
      today = "Sunday"; 
     } 

     int system_hour = d.getHours(); 
     int system_minute = d.getMinutes(); 
     cr.moveToFirst(); 
     for (int i = 0; i < cr.getCount(); i++) { 
      if (cr.getString(3).equals(system_hour + ":" + system_minute) 
        && cr.getString(1).equals("Daily")) { 
       Intent scheduledIntent = new Intent(context, MyScheduledActivity.class); 
       scheduledIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
       context.startActivity(scheduledIntent); 

       break; 

      } else if (cr.getString(3).equals(
        system_hour + ":" + system_minute) 
        && cr.getString(1).equals(today)) { 

       Intent scheduledIntent = new Intent(context, MyScheduledActivity.class); 
       scheduledIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
       context.startActivity(scheduledIntent); 

       break; 
      } else { 
       System.out.println("No Matching"); 
      } 
      cr.moveToNext(); 
     } 
    } 
    cr.close(); 
    mDba.close(); 
} 

}

尝试是这样的

Calendar calendar = Calendar.getInstance(); 

    int day = calendar.get(Calendar.DAY_OF_WEEK); 

    alarmManager.set(AlarmManager.RTC_WAKEUP, startTimmer.getTimeInMillis(),day * 7, pendingIntent1);
