我在 Android 應用程序中有一個選項可以設置兩個通知?；旧希斢脩魡螕舭粹o時，將顯示一個時間選擇器，在第一次選擇器完成后，將彈出第二個時間選擇器供用戶第二次插入。兩個時間選擇器都在不同的方法中，在第一種方法結束時顯示吐司，與第二種方法相同。問題是當第一次選擇器完成時，兩條吐司消息立即觸發，然后當用戶第二次完成選擇器時，第二條吐司消息再次觸發。我已經包含了下面的代碼。 /** * Method which sets the first daily notification */private void startTwiceDailyNotification(Calendar c) {    DialogFragment timePicker = new TimePickerFragment();    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);    Intent intent = new Intent(this, AlertReceiver.class);    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 1, intent, 0);    alarmManager.setExact(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pendingIntent);    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);    Toast.makeText(this, "First Notification Set.", Toast.LENGTH_SHORT).show();    timePicker.show(getSupportFragmentManager(), "time picker4");    hasSelected = 2;}/** * Method which sets the second daily notification */private void startTwiceDailyNotification2(Calendar c) {    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);    Intent intent = new Intent(this, AlertReceiver.class);    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 2, intent, 0);    alarmManager.setExact(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pendingIntent);    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);    Toast.makeText(this, "Second Notification Set.", Toast.LENGTH_SHORT).show();}
