title: Android findViewById in DialogFragment
body: <p>I am trying to develop a date picker that sets the value of a text view when set.</p>
  
  <p>But I cannot select the TV from the <code>DialogFragment</code> that handles the date picker.</p>
  
  <p>I tried <code>getView</code> but the application crashes at the specific point. </p>
  
  <p>Here's my code:</p>
  
  <pre><code>@SuppressLint("NewApi")
  public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
  
      TextView mTextView;
  
      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container,
              Bundle savedInstanceState) {
  
                  // R.layout.my_layout - that's the layout where your textview is placed
          View view = inflater.inflate(R.layout.activity_register_screen, container, false);
          mTextView = (TextView) view.findViewById(R.id.tvDate);
          // you can use your textview.
          return view;
      }
  
      @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 year, int month, int day) {
          int syear = year;
          int smonth = month;
          int sday = day;
          // set selected date into textview
          mTextView.setText(new StringBuilder().append(smonth + 1)
             .append("-").append(sday).append("-").append(syear)
             .append(" "));
      }
  }
