        getMenuInflater().inflate(R.menu.menu_main, menu);

        MenuItem item = menu.findItem(R.id.action_search);
        searchView.setMenuItem(item);

        return super.onCreateOptionsMenu(menu);;
    }

5.监听

MaterialSearchView searchView = (MaterialSearchView) findViewById(R.id.search_view);
    searchView.setOnQueryTextListener(new MaterialSearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                //Do some magic
                //点击搜索按钮提交搜索的内容
                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                //Do some magic
                //搜索框中内容发生改变
                return false;
            }
        });

        searchView.setOnSearchViewListener(new MaterialSearchView.SearchViewListener() {
            @Override
            public void onSearchViewShown() {
                //Do some magic
                //搜索框展开
            }

            @Override
            public void onSearchViewClosed() {
                //Do some magic
                //搜索框折叠
            }
        });
