我制作了一个自定义动画滑动菜单（如fb），我必须在子布局中插入一个列表视图。但是listview是在一个不同的类中，使用lazyadapter通过json解析。
这是我的MainActivity

我的问题是如何在MainActivity的子布局中显示JSONParsingActivity的列表视图。
我是Android编程的新手...... Plz帮助..
提前致谢..
答案 0 :(得分：1)
使用ListFragment扩展您的JSONParsingActivity。在主Activity中加载JSONParsingActivity。
已更新为代码
FragmentManager fragmentManager = getFragmentManager()
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
然后，您可以使用add（）方法添加片段，指定要添加的片段以及要插入的视图。
ExampleFragment fragment = new ExampleFragment();
fragmentTransaction.add(R.id.fragment_container, fragment);
fragmentTransaction.commit();
请refer this link，这里解释有关片段的所有内容。
这是在片段中设置UserInterface的方法。第一个解决方案1。
public static class ExampleFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.example_fragment, container, false);
}
}
解决第二个问题。
LazyAdapter(getActivity(), ArrayList<HashMap<String,String>>)
