RadioGroup 在片段 android 中不工作
RadioGroup not working in fragment android
我遇到了无线电检查更改侦听器在 android 片段中不起作用的问题，我在 activity 中尝试过它会正常工作，而我转换成片段时它不会给出任何响应，请帮助我，这是我的代码。

RadioGroup 直接只包含 RadioButtons，没有其他布局，如果你在 RadioGroup 中添加 LinearLayout，它不会工作，因为你 expect.Only 使用 RadioButtons 作为 RadioGroup 的子项。
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。
更新您的 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) {
