Set fragment edittext value from dialogfragment

Question

I'm trying to create searchdate. Here is what i do here is RijekSearch.java

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_rijek_search, container, false);
    EditText start = (EditText) v.findViewById(R.id.startdateval);

    start.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            FragmentManager fm = getFragmentManager();
            DatePickerFragment myDialogFragment = new DatePickerFragment();
            myDialogFragment.show(fm, "dialog_fragment");
        }
    });
    return v;
}

and here isDatePickerFragment

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {


    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        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);
    }

    @Override
    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());


        Fragment fr =   new RijekSearch();
        FragmentManager fm=getFragmentManager();
        FragmentTransaction ft=fm.beginTransaction();
        Bundle args = new Bundle();
        args.putString("startval", formattedDate);
        fr.setArguments(args);
        ft.replace(R.id.content_frame, fr);
        ft.commit();

    }
}

So. First i open the RijekSearch which is a fragment. then after i click start (EditText) it will show dialogfragment (DatePickerFragment). There is no problem with showing and there is no error.

My problem is , how can i set the start value after i choose the date from my DatePickerFragment ?

Two ways to do so: 1. Create a public static editText(Not Recommended, memory leaks). 2. Create listener and pass the instance in the dialog fragment.

Create interface DateCallback

interface DateCallback{
  void onDateSet(String fDate);
}

Aquire this in DialogFragment params

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

    private static DataCallback dataCallback;

    public static DatePickerFragment  newInstance(DataCallback dataCallback){
      this.dataCallback = dataCallback;
     return new DatePickerFragment();
    }
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        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);
    }

    @Override
    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());
        FragmentManager fm=getFragmentManager();
        dataCallback.onDateSet(formattedDate);
        fm.popBackStack();
    }
}

Now in your RijekSearch

start.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            FragmentManager fm = getFragmentManager();
            DatePickerFragment myDialogFragment = DatePickerFragment.newInstance(new DateCallback(){
                  @Override
                  public void onDateSet(String fDate){
                     start.setText(fDate);
                  }
            });
            myDialogFragment.show(fm, "dialog_fragment");
        }
    });

in this part ` this.dataCallback = dataCallback;` i get an error `cannot be referenced from a static context` — YVS1102, Feb 21 '18 at 06:14

You need to pass EditText data one Fragment to DialogFragment

First remove this start.setOnClickListener() you can use these

1 -on Text Change Listener

2 - FocusChangeListener

3 -Search and handle its click

on Action pass EditText data

Bundle args = new Bundle();
args.putString("key", "value");
DialogFragment newFragment = new YourDialogFragment();  
newFragment.setArguments(args);
newFragment.show(getSupportFragmentManager(), "TAG");

and get value in DialogFragment

Bundle mArgs = getArguments();
String myValue = mArgs.getString("key");
