如何在儿童列表部分中添加单选按钮，并获取所有选定的RadioButtons on Clist按钮的值

Question

在这里，我确实有一个多Expandable listView，我想在子零件中添加无线电按钮，并在单击"提交"按钮（类似于表单帖子）上获取所有选定的无线电按钮的值。有人可以帮助我使用代码

吗？

Answer 1

我始终使用此解决方案，希望它对您有帮助！

主动脉应扩展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>

以这种方式将我的抛弃添加到主动脉的容器中：

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

myFragment将扩展ListFragment。现在，您必须创建一个像这样的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;
}
}

最后在您的片段中：

@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);
}
