Android - 日期選擇器 - Obatin值

Question

我在我的活動中使用DatePicker對話框以供用戶選擇日期。 我想要做的是在textView中顯示選定的日期。任何人都可以請幫助我如何獲得選定的日期，然後相應地顯示它。 在此先感謝！

以下是我使用來實現的DatePicker對話框代碼：

public static class DatePickerFragment extends DialogFragment 
implements DatePickerDialog.OnDateSetListener { 

     @Override 
      public Dialog onCreateDialog(Bundle savedInstanceState) { 
       // Use the current date as the default date in the picker 
       final Calendar c = Calendar.getInstance(); 
        int year = c.get(Calendar.YEAR); 
        int month = c.get(Calendar.MONTH); 
        int day = c.get(Calendar.DAY_OF_MONTH); 

        // Create a new instance of DatePickerDialog and return it 
        return new DatePickerDialog(getActivity(), this, year, month, day); 
      } 

      public void onDateSet(DatePicker view, int yyyy, int mm, int dd) { 
      // Do something with the date chosen by the user 


      } 
} 

public void showDatePickerDialog(View v) { 
    DialogFragment newFragment = new DatePickerFragment(); 
    newFragment.show(getFragmentManager(), "datePicker"); 
} 

Answer 1

在onDateSet方法

，

String cuurent_date = String.valueOf(c.get(Calendar.DAY_OF_MONTH)) 
      + "/" + String.valueOf(c.get(Calendar.MONTH) + 1) + "/" 
      + String.valueOf(c.get(Calendar.YEAR));

在您的活動實現一個監聽器接口，並把它傳遞給DatePickerFragment。然後通過調用它的方法來觸發偵聽器。這裏描述：http://developer.android.com/guide/topics/ui/dialogs.html#PassingEvents
