Fragment Dialog and Date-Time Picker

With the fragment use we often need to use dialog with fragment. Here we will see how to use dialog with fragment and How to use Date-Time picker with the fragment.

Note: Check Fragment.

1. Extend DialogFragment:

public class CustomDialogFragment extends DialogFragment{

       //Define constants for date-time picker.

       public final int DATE_PICKER = 1;

       public final int TIME_PICKER = 2;

       public final int DIALOG = 3;

}

2. Add constructor with Fragment argument as It will let know over which fragment, the dialog should be shown.

private Fragment mCurrentFragment;

public CustomDialogFragment ( Fragment fragment ) {

        mCurrentFragment = fragment;

}

3.  Override onCreateDialog:

public Dialog onCreateDialog(Bundle savedInstanceState) {

        Bundle bundle = new Bundle();

        bundle = getArguments();

        int id = bundle.getInt("dialog_id");

        switch (id) {

        case DATE_PICKER:

            return new DatePickerDialog(getActivity(),

                    (OnDateSetListener)mCurrentFragment, bundle.getInt("year"),

                    bundle.getInt("month"), bundle.getInt("day"));

   

       case TIME_PICKER:

            return new TimePickerDialog(getActivity(),

                    (OnTimeSetListener)mCurrentFragment,          bundle.getInt("hour"),

                    bundle.getInt("minute"), false);

        }

       case DIALOG:

       //Define your custom dialog or alert dialog here and return it.

       return dialog;

    }

Note: Implement OnDateSetListener, OnTimeSetListener on Fragment.

4. Show the dialog:

CustomDialogFragment dialog = new CustomDialogFragment(YourFragment.this);

Bundle bundle = new Bundle();

bundle.putInt("dialog_id", DATE_PICKER);

bundle.putInt("year", mYear);

bundle.putInt("month", mMonth);

bundle.putInt("day", mDay);

dialog.setArguments(bundle);

dialog.show(getFragmentManager(), "dialog");
