android - Recyclerview 叠加工具栏

Question

我使用新的com.android.support:design:22.2.0库。当 recyclerview 初始化时，它会覆盖工具栏。我认为这是因为不正确的初始化recyclerview。我还尝试在单个文件中插入 recyclerview ，但我无法理解如何填充它

 super.onCreate(savedInstanceState);
    setContentView(R.layout.home);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    final ActionBar ab = getSupportActionBar();
    if (ab != null) {
       ab.setHomeAsUpIndicator(R.drawable.menu_and);
       ab.setDisplayHomeAsUpEnabled(true);
       }
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    if (navigationView != null) {
    setupDrawerContent(navigationView);
    }
    lNews.clear();
    populatedata();
    mLinearLayoutManager = new LinearLayoutManager(getApplicationContext());
    mRecyclerView = (RecyclerView)findViewById(R.id.recycleralda);
    mRecyclerView.setLayoutManager(mLinearLayoutManager);
    mRecyclerView.setItemAnimator(new DefaultItemAnimator());
    mRecyclerviewAdapter = new RecyclerViewAdapter(getApplicationContext());
    mRecyclerviewAdapter.loadNews(lNews);
    mRecyclerView.setAdapter(mRecyclerviewAdapter);

home.xml

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
