Create a DatePicker and TimePicker in the Tab Fragment error

Question

I am trying to create date picker and number picker inside a tab fragment, but its getting error. I can't figure it out the error or I am doing at a wrong way because of extends fragment is different than the extends AppCompatActivity??

Can someone please point out what am I missing and guild ?

 public class KeyInWeightF extends Fragment implements View.OnClickListener {

        View contentView;
        EditText btnTime;
        EditText btnDate;
    TimePickerDialog timePickerDialog;
    DatePickerDialog datePickerDialog;

    Calendar calender = Calendar.getInstance();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        contentView=inflater.inflate(R.layout.daily_weight_fragement, container, false);
        return contentView;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        btnTime = (EditText) contentView.findViewById(R.id.time_field);
        btnTime.setOnClickListener(this);
        btnDate = (EditText) contentView.findViewById(R.id.date_field);
        btnDate.setOnClickListener(this);
    }

    @Override
    public void onClick(View v){

        switch (v.getId()){

            case R.id.time_field:

                timePickerDialog = new TimePickerDialog(KeyInWeightF.this, new TimePickerDialog.OnTimeSetListener() {
                    @Override
                    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

                        Calendar timeCalendar = Calendar.getInstance();
                        timeCalendar.set(Calendar.HOUR_OF_DAY,hourOfDay);
                        timeCalendar.set(Calendar.MINUTE,minute);

                        String timestring = DateUtils.formatDateTime(KeyInWeightF.this,timeCalendar.getTimeInMillis(),DateUtils.FORMAT_SHOW_TIME);
                                                                     // KeyInWeightF.this error
                        btnTime.setText("Time:"+timestring);



                    }
                },calender.get(Calendar.HOUR_OF_DAY),calender.get(Calendar.MINUTE),android.text.format.DateFormat.is24HourFormat(KeyInWeightF.this));
                                                                                                                                       //KeyInWeightF.this error
                timePickerDialog.show();
                break;

            case R.id.date_field:{

                datePickerDialog =new DatePickerDialog(KeyInWeightF.this, new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

                        Calendar dateCalender = Calendar.getInstance();
                        dateCalender.set(Calendar.YEAR,year);
                        dateCalender.set(Calendar.MONTH,monthOfYear);
                        dateCalender.set(Calendar.DAY_OF_MONTH,dayOfMonth);

                        String dateString = DateUtils.formatDateTime(KeyInWeightF.this,dateCalender.getTimeInMillis(),DateUtils.FORMAT_SHOW_TIME);
                                                                     // error of KeyInWeightF.this why ?
                        btnDate.setText("Date:" + dateString);
                    }
                },calender.get(Calendar.YEAR),calender.get(Calendar.MONTH),calender.get(Calendar.DAY_OF_MONTH));

                datePickerDialog.show();
                break;

        }
    }
}

At first rectify your onCreateView method .

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            contentView=inflater.inflate(R.layout.daily_weight_fragement, container, false);
            btnTime = (EditText) contentView.findViewById(R.id.time_field);
            btnTime.setOnClickListener(this);
            btnDate = (EditText) contentView.findViewById(R.id.date_field);
            btnDate.setOnClickListener(this);
            return contentView;
        }

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);


        }

Logcat Returns

Solutions

You should use getActivity() instead of KeyInWeightF.this

getActivity() in a Fragment returns the Activity the Fragment is currently associated with.

timePickerDialog = new TimePickerDialog(getActivity(), new TimePickerDialog.OnTimeSetListener() {

As same as

  String timestring = DateUtils.formatDateTime(getActivity(),timeCalendar.getTimeInMillis(),DateUtils.FORMAT_SHOW_TIME);

Thank OK i try, later get back to you – Wg Sam Dec 08 '15 at 09:37 — Wg Sam, Dec 08 '15 at 09:37

You should use getActivity() instead of SomeActiviyy.this

datePickerDialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener()
