사용자 지정 대화 상자의 날짜 선택 도구 (DatePickerDialog가 아님) 과거 날짜가 작동하지 않는 제한

Question

대개 사람들과 마찬가지로 DatepickerDialog에없는 사용자 지정 대화 상자에 날짜 선택 도구가 만들어졌습니다. 문제는 과거의 날짜를 제한하려고 할 때 런타임 응용 프로그램이 충돌 할 때 첨부 된 코드를 로그 아웃합니다. 내 코드에서 빠진 것이있을 수 있습니다. [attach], 도와주세요.

코드 :

, view.UpdateDate()가 초기화에서 호출 할 수 없습니다 (익명의 내부 클래스 형 ..) 충돌이 이유 을, 나쁜 프로그래밍에 대한 죄송합니다

DatePicker datePicker = (DatePicker)datePickerDialog.findViewById(R.id.datepicker); 
     getCurrDate(); 

     datePicker.init(year, month, day, new OnDateChangedListener() { 

      @Override 
      public void onDateChanged(DatePicker view, int selected_year, int selected_month, 
        int selected_day) { 
       // TODO Auto-generated method stub 
      /// getCurrDate(); 
       if (selected_year < currYear) 
        view.updateDate(currYear, currMonth, currDay); 


       if (selected_month < currMonth && selected_year == currYear); 
        view.updateDate(currYear, currMonth, currDay); 

       if (selected_month < currDay && year == currYear && selected_month == currMonth) 
        view.updateDate(currYear, currMonth, currDay); 

       selectedDate = ""+(selected_month+1)+"/"+selected_day+"/"+selected_year; 
       datePicker_TV.setText(selectedDate); 

       repeatDlgDoneBtn.setTextColor(getResources().getColor(R.color.Dialog_cancel_blue)); 
       repeatDlgDoneBtn.setEnabled(true); 
       getSelectedWeek(); 
      } 
     });  
     datePicker.setCalendarViewShown(false);   
     datePicker.setDescendantFocusability(DatePicker.FOCUS_BLOCK_DESCENDANTS); 
     datePickerDialog.show(); 

    } 

Answer 1

같은 논리 불구하고 DatePickerDialog 객체를 다음과 같이 가져갈 때 적용 할 수 있습니다.

new DatePickerDialog.OnDateSetListener() { 

      @Override 
      public void onDateSet(DatePicker view, int year, int monthOfYear, 
        int dayOfMonth) { 
       // TODO Auto-generated 
................................. 
................................. 
same logic as above code works for this scenario. 

But i had used a Custom Dialog to increase UI Flexibility, so here's the perfect solution: 
1. 1st get the Time in Millis for the Past Date[Called Min Date to be set in Date Picker] 
2. If it is Current Date then do not use current time System.getCurrentTimeinMillis(); as it's always greater than the Actual date's Initial Time so using this will crash DatePicker. Instead send this current date to a date to time converter function as i had mentioned below: 





public void getCurrDate() 
    { 
    Calendar c = Calendar.getInstance(); 
      year = c.get(Calendar.YEAR); 
      month = c.get(Calendar.MONTH); 
      day = c.get(Calendar.DAY_OF_MONTH); 

      return ""+(month+1)+"/"+day+"/"+year; 
    } 
    String input = getCurrDate(); 
      Date date; 
      try { 
       date = new SimpleDateFormat("MM/dd/yyyy", Locale.ENGLISH).parse(input); 
       long milliseconds = date.getTime(); 
       if(milliseconds>0){ 
        datePicker.setMinDate(milliseconds); 
    //This Function will work fine, to set a future constraint use setMaxDate(long time); 
       } 
       else 
       { 
           //whatever else cond... 
       } 

      } catch (ParseException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      }
