How to passed the value of DatePickerDialog to different editText?

Question

I have created two different editText, previous Inspection Date and current inspection date . I'm using fragment and DatePickerDialog to get the dates. Each editText will have their own dates. How do I passed the dates in datePickerDialog?

Ps I'm using onFocusChange so that the dialog popup when user click on editText. Using setOnClickListener will require user to double click to show the datePickerDialog.

FormFragment.java

public class FormFragment extends Fragment {

....

    //TODO : Fixed datepicker & time picker

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

    //get time func
    public void showTimePickerDialog(View v) {
        DialogFragment newFragment = new TimePickerFragment();
        newFragment.show(getFragmentManager(), "timePicker");
    }


    public void onViewCreated(final View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        //get CaseDetailActivity
        final Activity activity = this.getActivity();

        /*
        Use onFocusChangeListener - the dialog automatically popped when clicked on edittext
        */

        //inspection date
        final View editText_date = activity.findViewById(R.id.input_inspecDateNew);
        editText_date.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    //get current text
                    showDatePickerDialog(v);
                }
            }
        });

        //previous inspection date
        View editText_prevDate = activity.findViewById(R.id.input_lastInspecDate);
        editText_prevDate.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    //get current text
                    showDatePickerDialog(v);
                }
            }
        });
    }
}

DatePickerFragment.java

public class DatePickerFragment extends DialogFragment
        implements DatePickerDialog.OnDateSetListener {

    public static EditText editText;

    @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 getCurrentDate () {
        Calendar c = Calendar.getInstance();
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
        String formattedDate = df.format(c.getTime());

        editText.setText(formattedDate);
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {
        Calendar c = Calendar.getInstance();
        c.set(year, month, day);

        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        String formattedDate = sdf.format(c.getTime());

        editText.setText(formattedDate);
    }
}

You can use setTargetFragment and onActivityResult to achieve this,

You can try like this

FormFragment.java

public class FormFragment extends Fragment {

    private static final String TAG = FormFragment.class.getSimpleName();

    private static final int REQUEST_CODE_INSPECDATENEW = 200;
    private static final int REQUEST_CODE_LASTINSPECDATE = 201;

    private EditText editText_date;
    private EditText editText_prevDate;

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_blank2, container, false);
    }

    //get Date func
    public void showDatePickerDialog(View v, int requestCode) {
        DialogFragment newFragment = new DatePickerFragment();
        newFragment.setTargetFragment(this, requestCode);
        newFragment.show(getFragmentManager(), "datePicker");
    }

    public void onViewCreated(final View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        //inspection date
        editText_date = view.findViewById(R.id.input_inspecDateNew);
        editText_date.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    //get current text
                    showDatePickerDialog(v, REQUEST_CODE_INSPECDATENEW);
                }
            }
        });

        //previous inspection date
        editText_prevDate = view.findViewById(R.id.input_lastInspecDate);
        editText_prevDate.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    //get current text
                    showDatePickerDialog(v, REQUEST_CODE_LASTINSPECDATE);
                }
            }
        });
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        Log.d(TAG, "onActivityResult: ");

        if (resultCode == Activity.RESULT_OK) {
            if (data == null) {
                return;
            }

            String dataValue = data.getStringExtra("value");

            if (requestCode == REQUEST_CODE_INSPECDATENEW) {
                editText_date.setText(dataValue);
            } else if (requestCode == REQUEST_CODE_LASTINSPECDATE) {
                editText_prevDate.setText(dataValue);
            }
        }
    }
}
