이다, 시작 날짜 및 종료 날짜 수 제대로 설정하십시오. 종료일은 시작일 이전에 설정할 수 없습니다. 그러나 끝 날짜를 먼저 설정하고 시작 날짜를 설정하면 ...이 경우 제대로 작동하지 않습니다. 이 사건을 처리하는 방법 ??? 나는 또한 시작과 끝 날짜가 같을 수 없으며 사용자가 오늘 날짜 이전에 날짜를 선택할 수 없도록해야합니다 ... 조건을 넣을 위치는 어디입니까 ?? 어떻게해야합니까 ?? 제발 도와주세요 ...

Answer 1

다음과 같이 끝 날짜 수신기를 변경합니다.

if(v==b_end_calender) { 
    final Calendar c=Calendar.getInstance(); 
    end_year=c.get(Calendar.YEAR); 
    end_month=c.get(Calendar.MONTH); 
    end_day=c.get(Calendar.DAY_OF_MONTH); 

    DatePickerDialog.OnDateSetListener mDateSetListener 
     = new DatePickerDialog.OnDateSetListener() { 
      public void onDateSet(DatePicker view, 
       int year, int monthOfYear, int dayOfMonth) { 
       Calendar newEndDate = Calendar.getInstance(); 
       newEndDate.set(Calendar.YEAR, year); 
       newEndDate.set(Calendar.MONTH, monthOfYear); 
       newEndDate.set(Calendar.DAY_OF_MONTH, dayOfMonth); 

       if(newEndDate.before(startDate)) { 
        // handle the error 
       } else { 
       end_date.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year); 
       } 

      } 
    }; 

    new DatePickerDialog(getActivity(), 
     mDateSetListener, end_year, end_month, end_day).show(); 

} 당신이 발견하는 경우

, 내가 전역 변수 startDate을 사용하고 있습니다. 선택 될 때 전역 적으로 저장해야합니다.

Calendar startDate = Calendar.getInstance(); // global variable 

if(v==b_start_calender) { 
    final Calendar c=Calendar.getInstance(); 
    start_year=c.get(Calendar.YEAR); 
    start_month=c.get(Calendar.MONTH); 
    start_day=c.get(Calendar.DAY_OF_MONTH); 

    DatePickerDialog.OnDateSetListener mDateSetListener 
     = new DatePickerDialog.OnDateSetListener() { 
      public void onDateSet(DatePicker view, 
       int year, int monthOfYear, int dayOfMonth) { 
        startDate.set(Calendar.YEAR, year); 
        startDate.set(Calendar.MONTH, monthOfYear); 
        startDate.set(Calendar.DAY_OF_MONTH, dayOfMonth); 
        start_date.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year); 
     } 
    }; 

    new DatePickerDialog(getActivity(), 
     mDateSetListener, start_year, start_month, start_day).show(); 
} 

두 번째로, DateFormatter 클래스를 살펴보면, 나는 그들이 당신에게 유용 할 것이라고 확신합니다.

건배.
