Question

我在互联网上搜索过，但我找不到合适的解决方案。我相信这很简单。

我有抽屉布局，有了它我想打开一个列表视图。当我单独打开列表视图时，它工作正常，但是当我尝试通过带有充气的抽屉打开它时，我收到错误或屏幕为空。我可以通过普通视图来充气。

有人可以帮帮我吗？非常感谢！

public static class MyFragment extends Fragment {
    public static final String ARG_ITEM_NUMBER = "int_number";

    public MyFragment() {
        // Empty constructor required for fragment subclasses
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        ListView myListView = (ListView) inflater.inflate(R.layout.activity_list_view,container,false);

        return myListView;
    }
}

activity_main.xml中

     space available using match_parent in both dimensions. -->

    // Create ArrayAdapter using the planet list.  
    listAdapter = new ArrayAdapter<String>(this, R.layout.listview_row, planetList);  

    // Add more planets. If you passed a String[] instead of a List<String>   
    // into the ArrayAdapter constructor, you must not add more items.   
    // Otherwise an exception will occur.
