Question

我是Android编程的新手。最近我正在尝试构建一个需要抽象布局的应用程序。我按照Android开发者指南中的示例，似乎找到但我发现我无法将onItemClicklistener设置为drawerLayout中的listView。

我试图谷歌它，发现没有任何帮助（setfocusable（false）不起作用）。我的片段包含listview和recyclerview。当我使用调试模式时，我发现程序甚至无法进入onItemClick方法。希望任何人都可以提供帮助！

  private class DrawerItemClickListener implements ListView.OnItemClickListener {
    @Override
    public void onItemClick(AdapterView parent, View view, int position, long id) {
        mDrawerList.setItemChecked(position, true);
    }
}


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

    View rootView = inflater.inflate(R.layout.fragment_enter, container, false);
    RecyclerView mRecyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_main_content);
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getActivity());

    rootView.findViewById(R.id.button_add_question).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getActivity(), NewQuestionActivity.class);
            startActivity(intent);
        }
    });

    DrawerLayout mDrawerLayout = (DrawerLayout) rootView.findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) rootView.findViewById(R.id.left_drawer);

    mDrawerList.setAdapter(new ArrayAdapter<>(this.getActivity(), R.layout.list_item_main_drawer, mDrawerItem));
    mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

    mRecyclerView.setLayoutManager(mLayoutManager);

    mAdapter = new MainContentListAdapter(mList);
    mRecyclerView.setAdapter(mAdapter);


    mRecyclerView.addOnItemTouchListener(
            new RecyclerItemClickListener(getActivity(), new RecyclerItemClickListener.OnItemClickListener() {
                @Override
                public void onItemClick(View view, int position) {
                    Intent intent = new Intent(getActivity(), DetailActivity.class);
                    intent.putExtra("questionId", mList.get(position).getQuestionId());
                    startActivity(intent);
                }
            })
    );

    return rootView;
}

我的XML文件

更新

我发现listView总是在recyclerView后面，也许这就是问题所在。但是，我尝试过bringToFront，但似乎也无效。有什么帮助吗？

尝试做这样的事情：

drawerListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> arg0, View view,
                        int position, long id) {
                 Intent intent = new Intent(getActivity(), DetailActivity.class);
                intent.putExtra("questionId", mList.get(position).getQuestionId());
                startActivity(intent);
    }
            });

而不是：

mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

在drawerlayout中默认listview的onitemclick不起作用
