I have faced an issue radio check change listener not working in the android fragment, I tried this within an activity it will work fine, while I convert into fragment it will give no response, please help me, here is my code.

K06_Away.java

 public class K06_Away extends Fragment {

        private View kf06_view;
        protected Typeface tfLatoBold,tfLatoMedium,tfLatoRegular;
        private Button button_kf06_back,button_kf06_next;
        private TextView txtVw_kf06_resident_away;
        private EditText edTxt_kf06_visiting_lastname;
        private RadioGroup radioGp_kf06_resident_away;
        List<RadioButton> radioButtons = new ArrayList<RadioButton>();

        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            kf06_view = inflater.inflate(R.layout.k06_away, container, false);

            return kf06_view;
        }

        @Override
        public void onViewCreated(View view, Bundle savedInstanceState) {
            super.onViewCreated(view, savedInstanceState);
                   configViews();
        }


        private void configViews() {
            button_kf06_back = (Button) kf06_view.findViewById(R.id.button_kf06_back);
            button_kf06_next = (Button) kf06_view.findViewById(R.id.button_kf06_next);
            txtVw_kf06_resident_away= (TextView) kf06_view.findViewById(R.id.txtVw_kf06_resident_away);

            radioGp_kf06_resident_away = (RadioGroup) kf06_view.findViewById(R.id.radioGp_kf06_resident_away);
            radioButtons.add( (RadioButton)kf06_view.findViewById(R.id.radio_kf06_1_2_hours) );
            radioButtons.add( (RadioButton)kf06_view.findViewById(R.id.radio_kf06_halfday) );
            radioButtons.add( (RadioButton)kf06_view.findViewById(R.id.radio_kf06_allday) );
            radioButtons.add( (RadioButton)kf06_view.findViewById(R.id.radio_kf06_moreday) );

            configClickListeners();
            radioButtonAction();



        }
        private void configClickListeners() {
            button_kf06_back.setOnClickListener(this);
            button_kf06_next.setOnClickListener(this);
        }
        private void radioButtonAction(){
            for (RadioButton button : radioButtons){
                button.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){
                    @Override
                    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                        if (isChecked) processRadioButtonClick(buttonView);
                        String radio_Text = buttonView.getText().toString();
                        int radio_Id = buttonView.getId();
                        System.out.println("Selected the Radio:"+radio_Text+", Radio-Id:"+radio_Id);
                    }
                });

            }

Answer 1

RadioGroup Directly contain only RadioButtons,No other Layouts,if you add LinearLayout inside RadioGroup,it will not works as you expect.Only use RadioButtons as child of RadioGroup.

Answer 2

1. Try to call method configViews() from onCreateView() and pass the view kf06_view as parameter.

2. Implement View.OnClickListener to handle button_kf06_back and button_kf06_next click events.

Update your K06_Away Fragment as below:

public class K06_Away extends Fragment implements View.OnClickListener {

    protected Typeface tfLatoBold,tfLatoMedium,tfLatoRegular;
    private Button button_kf06_back,button_kf06_next;
    private TextView txtVw_kf06_resident_away;
    private EditText edTxt_kf06_visiting_lastname;
    private RadioGroup radioGp_kf06_resident_away;
    List<RadioButton> radioButtons = new ArrayList<RadioButton>();

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View kf06_view = inflater.inflate(R.layout.k06_away, container, false);

        // Init
        configViews(kf06_view);

        return kf06_view;
    }

    private void configViews(View view) {
        button_kf06_back = (Button) view.findViewById(R.id.button_kf06_back);
        button_kf06_next = (Button) view.findViewById(R.id.button_kf06_next);
        txtVw_kf06_resident_away= (TextView) view.findViewById(R.id.txtVw_kf06_resident_away);

        radioGp_kf06_resident_away = (RadioGroup) view.findViewById(R.id.radioGp_kf06_resident_away);
        radioButtons.add( (RadioButton) view.findViewById(R.id.radio_kf06_1_2_hours) );
        radioButtons.add( (RadioButton) view.findViewById(R.id.radio_kf06_halfday) );
        radioButtons.add( (RadioButton) view.findViewById(R.id.radio_kf06_allday) );
        radioButtons.add( (RadioButton) view.findViewById(R.id.radio_kf06_moreday) );

        configClickListeners();
        radioButtonAction();
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.button_kf06_back:
                // Do something...
                break;
            case R.id.button_kf06_next:
                // Do something...
                break;
        }
    }

    private void configClickListeners() {
        button_kf06_back.setOnClickListener(this);
        button_kf06_next.setOnClickListener(this);
    }

    private void radioButtonAction(){
        for (RadioButton button : radioButtons){
            button.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    if (isChecked) processRadioButtonClick(buttonView);
                    String radio_Text = buttonView.getText().toString();
                    int radio_Id = buttonView.getId();
                    System.out.println("Selected the Radio:"+radio_Text+", Radio-Id:"+radio_Id);
                }
            });
        }
    }

    private void processRadioButtonClick(CompoundButton buttonView){
        for (RadioButton button : radioButtons){
            if (button != buttonView ) button.setChecked(false);
        }
    }
}
