Außerdem verwende ich diese Bibliothek: https://github.com/mohamad-amin/PersianMaterialDateTimePicker

Sie benötigen zwei Zuhörer haben

DatePickerDialog.OnDateSetListener one_dateListener,two_dateListener; 

Listener Umsetzung wie folgt:

one_dateListener= new OnDateSetListener(){ 

      public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) { 

          ... 

       } 
      } 

     }; 
     two_dateListener= new OnDateSetListener(){ 
      public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) { 
       ..... 
      } 
     }; 

diese Zuhörer im Dialog verwenden:

int DATE_PICKER_TO = 0; 
int DATE_PICKER_FROM = 1; 

@Override 
protected Dialog onCreateDialog(int id) { 

    switch(id){ 
     case DATE_PICKER_ONE: 
       return new DatePickerDialog(this, one_dateListener, from_year, from_month, from_day); 
      case DATE_PICKER_TWO: 
       return new DatePickerDialog(this, two_dateListener, to_year, to_month, to_day); 
    } 
     return null; 
}
