android - Retrieve and set data from DialogFragment (DatePicker)

Question

My DialogFragment class is invoked when I press a button on a activity. I want the date set through this DialogFragment to be displayed on the buttons text. FindViewById refuses to be recognized by the class.

I found a similar question but I'm unable to relate it to my case.

Code:

1. Button which calls the Dialogue fragment:

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

2. Code for dialogue fragment:

   public class DatePickerFragment extends DialogFragment implements
       DatePickerDialog.OnDateSetListener {
   
       @Override
       public Dialog onCreateDialog(Bundle savedInstanceSateate) {
   
           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);
   
               return new DatePickerDialog(getActivity(), this, year, month, day);
           }
   
           public void onDateSet(DatePicker view, int year, int month, int day) {
               // Do something with the date chosen
           }
       }
   }
   

Answer 1

In the method in your DialogFragment that is in charge of being notified when the user sets the date, do this

Button activityButton = (Button)getActivity().findViewById(R.id.myButton);
activityButton.setText (myDate);
