在Android中創建模式日期選擇器對話框

Question

我有這個代碼工作正常，但窗口不是模態，所以我不能得到它被更改後的日期。請提前給我提供一些建議或方法。

下面是代碼：

final Calendar c = Calendar.getInstance(); 
int mYear = c.get(Calendar.YEAR); 
int mMonth = c.get(Calendar.MONTH); 
int mDay = c.get(Calendar.DAY_OF_MONTH); 

DatePickerDialog dpd = new DatePickerDialog(this, 
     new DatePickerDialog.OnDateSetListener() { 

      public void onDateSet(DatePicker view, int year, 
           int monthOfYear, int dayOfMonth) { 

       TextView txtDate = null; 
       txtDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year); 

      } 

      public void onDateSet1(DatePicker view, int year, 
            int monthOfYear, int dayOfMonth) { // TODO 
       // Auto-generated 
       // method stub 

      } 
     }, mYear, mMonth, mDay); 

dpd.show(); 

message("message", "Mensaje", mYear + "/" + mMonth + "/" + mDay, this, context);

private int storeYear = 0; 
private int storeMonth = 0; 
private int storeDay = 0; 

private void function openPicker(){ 
    final TextView txtDate = findViewById(R.id.yourid); 
    final Calendar c = Calendar.getInstance(); 
    int mYear = c.get(Calendar.YEAR); 
    int mMonth = c.get(Calendar.MONTH); 
    int mDay = c.get(Calendar.DAY_OF_MONTH); 

    DatePickerDialog dpd = new DatePickerDialog(this, 
      new DatePickerDialog.OnDateSetListener() { 

       public void onDateSet(DatePicker view, int year, 
         int monthOfYear, int dayOfMonth) { 

        //TextView txtDate = null; 
        txtDate.setText(dayOfMonth + "-" + (monthOfYear + 1) 
          + "-" + year); 
        storeYear = year;storeMonth = monthOfYear;storeDay = dayOfMonth; 

    message("message", "Mensaje", mYear + "/" + mMonth + "/" 
      + mDay, this, context); 
       } 

       public void onDateSet1(DatePicker view, int year, 
         int monthOfYear, int dayOfMonth) { // TODO 
                  // Auto-generated 
                  // method stub 

       } 
      }, mYear, mMonth, mDay); 
    dpd.show(); 

}
