android:descendantFocusability="blocksDescendants"
 android:background="#ffffff">
<ImageView
android:layout_width="30dp"

android:layout_marginRight="10dp"
android:src="@drawable/icon_checked" />    <WebView
android:layout_width="match_parent"

假设每个组的子元素都是a list of size equal to 1。因此,除了getChildView()getChildrenCount()之外,适配器的其他部分应该像往常一样。此外,您可以使用与组和子项相同的对象类型。

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View rowView, ViewGroup parent) {
        //String url = mList.get(groupPosition).getChildList().get(childPosition);
        String url = mList.get(groupPosition).getUrl();

        if (rowView == null) {
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            rowView = inflater.inflate(R.layout.fermata_adapter_body, null);
            mWebView = (WebView) rowView.findViewById(R.id....); 
            ...
        }
        mWebView.loadUrl(url);
        return rowView;
    }

    @Override
    public int getGroupCount() {
        return mList.size();
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        return 1;//every group has 1 child
    }
    @Override
    public Object getChild(int groupPosition, int childPosition) {
        return mList.get(groupPosition);//or mList.get(groupPosition).getUrl();
    }
    @Override
    public Object getGroup(int groupPosition) {
        return mList.get(groupPosition);
    }

为了更好的可用性,您可能需要使用Volley之类的网络库来加载网络内容,而不是简单地说mWebView.loadUrl(url)
