我正在尝试SearchView从支持库实现.我希望用户使用它SearchView来过滤一部List电影RecyclerView.

到目前为止我已经按照了几个教程添加SearchView了ActionBar,但是我不确定从哪里开始.我看过几个例子,但是当你开始输入时,它们都没有显示结果.

这是我的MainActivity:

public class MainActivity extends ActionBarActivity {

    RecyclerView mRecyclerView;
    RecyclerView.LayoutManager mLayoutManager;
    RecyclerView.Adapter mAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_recycler_view);

        mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
        mRecyclerView.setHasFixedSize(true);

        mLayoutManager = new LinearLayoutManager(this);
        mRecyclerView.setLayoutManager(mLayoutManager);

        mAdapter = new CardAdapter() {
            @Override
            public Filter getFilter() {
                return null;
            }
        };
        mRecyclerView.setAdapter(mAdapter);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar …
