Dialog Fragment to activity data transfer

Question

I have a DialogFragment with two buttons and two text field.

I only want that when I enter data in both text fields and press "ok" button then it can match the data of both fields and save result to a String. Toast msg is working correctly but how can I get data from fragment textfield?? Here is my Fragment code

public class chngpswd extends DialogFragment implements View.OnClickListener {

    Button ok,cancel;

    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState){
        View v=inflater.inflate(R.layout.activity_chngpswd,null);

        ok=(Button)v.findViewById(R.id.ok);
        cancel=(Button)v.findViewById(R.id.cancel);
        ok.setOnClickListener(this);
        cancel.setOnClickListener(this);
        setCancelable(false);
        return v;
    }

    @Override
    public void onClick(View v) {
        if(v.getId()==R.id.ok)
        {
            dismiss();
            Toast.makeText(getActivity(),"ok", Toast.LENGTH_LONG).show();
        }
        else {

            dismiss();
            Toast.makeText(getActivity(),"cancelled", Toast.LENGTH_LONG).show();
        }
    }
}

Code for xml used in the Fragment

You have to save references to the text fields in your onCreateView() (like you do with buttons) and use them to get the fields data:

Button ok, cancel;
EditText pass, cpass;

public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState){
    View v=inflater.inflate(R.layout.activity_chngpswd,null);

    ok=(Button)v.findViewById(R.id.ok);
    cancel=(Button)v.findViewById(R.id.cancel);

    pass = (EditText)v.findViewById(R.id.pass);
    cpass = (EditText)v.findViewById(R.id.cpass);

    ok.setOnClickListener(this);
    cancel.setOnClickListener(this);
    setCancelable(false);
    return v;
}

@Override
public void onClick(View v) {
    if(v.getId()==R.id.ok)
    {
        dismiss();
        String passData = pass.getText().toString();
        Toast.makeText(getActivity(),"ok: " + passData, Toast.LENGTH_LONG).show();
    }
    else {

        dismiss();
        Toast.makeText(getActivity(),"cancelled", Toast.LENGTH_LONG).show();
    }
}
