public class InvitationFragment extends Fragment {
    LayoutInflater inflater;
    ViewGroup container;
    Bundle savedInstanceState;
    private List<String> eventName = new ArrayList<>();
    private List<Long> eventId = new ArrayList<>();

    private UserMO userMO;
    private CheckBox invitationCheckBox;
    private ListView occasionView;
    private DatabaseHelper dbHelper;
    private View view;
    private SharedPreferences sharedpreferences;


    public boolean onOptionsItemSelected(MenuItem item) {
        Log.d("onOptionsItemSelected", "yes");

        switch (item.getItemId()) {
            case R.id.menu_cancel_event:
                displayInvitationList();
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }

    }

    public void displayInvitationList() {

        int itemCount = occasionView.getCheckedItemCount();
        for (int i = 1; i <= itemCount; i++) {
            if (userOccasions.getCheckedInvitationCount() != null) {
                SQLiteDatabase db = dbHelper.getWritableDatabase();
               // eventUserId = userOccasions.getCheckedInvitationCount();
               // db.delete("user_relation", "EVENT_USER_ID" + " = ?", new String[]{Long.toString(eventUserId)});
                db.close();
            }

}

here I have tried the following code for change the colour of the button when the button clicked but it will not hold the colour when we go back and return back to the button and it will work for all events

yesBtn.setbackgroundColor(color.Yellow);
noBtn.setbackgroundColor(color.blue);
maybeBtn.setbackgroundColor(color.blue);

the above mentioned code is under yesBtn.oncliclListener() method

here how to use shared preference to solve that issue

Answer 1

You can store color in shared preference as Int. But as a suggestion , you need not store color , but some flag value 1,2,3,etc and based on that value you can set your color on the button
