DatePickerDialog에 현재 날짜와 요일을 넣는 법

Question

DatePickerDialog를 사용하여 날짜를 설정하는 앱이 있습니다. 회 전자에서 날짜를 변경하면 위젯에 날짜와 요일이 표시됩니다. 이것은 2.3.3을 가진 samsung 소형에 달릴 때 일어난다. 그러나 htc 1 x에서 4.0.4를 실행하면 날짜와 요일이 컴파일되지 않습니다.

기기 나 Android 버전에 관계없이 날짜와 요일이 항상 위젯에 표시되도록하려면 어떻게해야합니까?

장치 또는 OS에 따라 위젯의 기본 동작을 일관성있게 무시해야하므로 위젯의 기본 동작을 재정의해야합니다. 감사합니다

@Override 
    protected Dialog onCreateDialog(int id) { 
     switch (id) { 
     case DATE_DIALOG_ID: 
      // set date picker as current date 

      return new DatePickerDialog(this, datePickerListener, year, month, day); 
     } 
     return null; 
    } 

    private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() { 

     // when dialog box is closed, below method will be called. 
     public void onDateSet(DatePicker view, int selectedYear, 
       int selectedMonth, int selectedDay) { 

      year = selectedYear; 
      month = selectedMonth; 
      day = selectedDay; 




      Intent i = new Intent(GetRota.this, NfcscannerActivity.class); 
      i.putExtra("nextRota", formattedSpinnyTime); 
      i.setAction("NEXT_ROTA"); 
      startActivity(i); 

     } 
    };

당신은 joda 시간 - 2.0.jar API를 사용할 수 있습니다. 이 API는 Datetime 클래스를가집니다. 이 수업에서 시간을 가질 수 있습니다.

DateTime datetime = DateTime.now();
