RadioGroup 在片段 android 中不起作用

Question

我遇到了一个问题无线电检查更改侦听器在 android 片段中不起作用，我在一个活动中尝试了它会正常工作，而我转换为片段时它不会给出任何响应，请帮助我，这是我的代码。

K06_Away.java

 public class K06_Away extends Fragment {

Answer 1

1.尝试从onCreateView()调用方法configViews()并将视图kf06_view作为参数传递。

2.实现View.OnClickListener来处理button_kf06_back和button_kf06_next点击事件。

更新你的K06_Away片段如下：

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);
        }
    }
}

Answer 2

RadioGroup直接只包含RadioButtons，没有其他Layouts，如果你在RadioGroup里面添加LinearLayout，它不会像你想象的那样工作。只能使用RadioButtons作为RadioGroup的子元素。
