这里我有一个multiexxandable listview，我想在子部分添加单选按钮，并在点击提交按钮（如表单POST）时获取所有选定单选按钮的值。有人可以用代码帮我吗

工作代码：

我总是使用这个解决方案，希望它对你有所帮助！

MainActivity应扩展FragmentActivity并具有以下布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/> 
</RelativeLayout>

比我以这种方式将MyFragment添加到MainActivity的容器中：

getSupportFragmentManager()
                .beginTransaction()
                .add(R.id.container, new MyFragment())
                .commit();

MyFragment将扩展ListFragment。现在你必须创建一个这样的customListAdapter：

public class CustomListAdapter extends BaseAdapter {
private LayoutInflater inflater;
private static final int TYPE_ITEM = 0;
private static final int MAX_COUNT = 1;

private ArrayList mData = new ArrayList();

public CustomListHomeAdapter(Context context) {
    inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

public void addItem(final HomeModel item) {
    mData.add(item);
    notifyDataSetChanged();
}


@Override
public int getItemViewType(int position) {
        return TYPE_ITEM;      
}

@Override
public int getViewTypeCount() {
    return MAX_COUNT;
}

@Override
public int getCount() {
    return mData.size();
}

@Override
public Object getItem(int position) {
    return mData.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder viewHolder = null;
    int type = getItemViewType(position);

    if(convertView == null) {
        //initialize the view Holder
        viewHolder = new ViewHolder();
        switch (type) {
            case TYPE_ITEM:
                convertView = inflater.inflate(R.layout.list_row_home, null);   //HERE YOU CAN INFLATE YOUR CUSTOM LAYOUT FOR A SINGLE ROW

                viewHolder.rb = (RadioButton) convertView.findViewById(R.id.radioButton);

                break;
        }

        convertView.setTag(viewHolder);
    } else {
        viewHolder = (ViewHolder) convertView.getTag();
    }

    HomeModel model;
    switch (type) {
        case TYPE_ITEM:
             viewHolder.rb.setChecked(true);
        break;

    }
    return convertView;
}

private static class ViewHolder {
    RadioButton rb;
}
}

最后在你的片段中：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //initialize all home items
    mAdapter = new CustomListHomeAdapter(getActivity());

    Resources resources = getResources();

    mAdapter.addItem(new HomeModel(getString(R.string.produttori_label), resources.getDrawable(R.drawable.produttori)));


    //initialize and set list adapter
    setListAdapter(mAdapter);

}
