date picker with fragment class android

Question

i am developing an application with the navigation drawer. when i click some items in the navigation list it shows some interface using a fragment. and my click items also working properly. i have use an image button to show a date picker. i have use below codes. but when i set an date from data picker dialog. it does not change the given text view. please guide me with some code samples..

public class FindPeopleFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener { public int year; public int month; public int day; static final int DATE_PICKER_ID = 1111; TextView curentDate; public FindPeopleFragment(TextView date){ curentDate = date; } public FindPeopleFragment(){ } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.schedule, container, false); ImageButton date = (ImageButton) rootView.findViewById(R.id.btnDate); curentDate = (TextView) rootView.findViewById(R.id.txtCurrentDate); /*final Calendar c = Calendar.getInstance(); year = c.get(Calendar.YEAR); month = c.get(Calendar.MONTH); day = c.get(Calendar.DAY_OF_MONTH); curentDate.setText(new StringBuilder() // Month is 0 based, just add 1 .append(month + 1).append("-").append(day).append("-") .append(year).append(" "));*/ date.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub //Toast.makeText(getActivity(), "clicked", Toast.LENGTH_LONG).show(); //showDialog(DATE_PICKER_ID); showDatePickerDialog(v); } }); return rootView; } public Dialog onCreateDialog(Bundle savedInstanceState) { final Calendar c = Calendar.getInstance(); year = c.get(Calendar.YEAR); month = c.get(Calendar.MONTH); day = c.get(Calendar.DAY_OF_MONTH); return new DatePickerDialog(getActivity(), datePickerListener, year, month, day); } private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener(){ public void onDateSet(DatePicker view, int syear, int smonth, int sday) { // Do something with the date chosen by the user month = smonth; day = sday; year = syear; curentDate.setText(String.valueOf(month + 1 ) + "/" + String.valueOf(day) + "/" + String.valueOf(year)); } }; public void showDatePickerDialog(View v) { DialogFragment newFragment = new DatePickerFragment(); newFragment.show(getFragmentManager(), "datePicker"); } @Override public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub }

}

Creating a constructor with params is a bad idea.

Use a interface as a call back to the activity and set the date selected to textview in activity or framgent.

hi i am not using activity here. when the user press an item on navigation list it is only show this fragment class. how can i do this with only the fragment without activity

@GishanthaDarshana you can't have a fragment without activity. Fragment is hosted by a activity. SO communicate date to activity. then activity to fragment. MainActivity is the one that hosts the framgents. You will have a container you just add or replace framgents.
