伙计们我需要一些帮助.我一直在尝试在我的项目中实现SearchView.但是我的项目包含一个列表视图,附带了一个自定义适配器.我搜索了很多站点,但都有使用arrayadapter实现的示例. .假设我有一个Employee类,它包含名称和年龄字段.如何使用他们的名称来过滤员工..

public class MainActivity extends Activity implements SearchView.OnQueryTextListener
{
SearchView mSearchView;
ListView mListView;
//String mStrings[]= {"abc","def","efg","ghi","ijk","apple","agxhsdgc","abbbcc"};
ArrayList<Employee> emp_list=null;
EmployeeAdapter emp_adapter=null;

    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mSearchView=(SearchView) findViewById(R.id.searchView1);
        mListView=(ListView) findViewById(R.id.listView1);

        emp_list=new ArrayList<Employee>();
        emp_list.add(new Employee("ABC", 24));
        emp_list.add(new Employee("ACB", 24));
        emp_list.add(new Employee("BVF", 28));
        emp_list.add(new Employee("BRT", 28));
        emp_list.add(new Employee("ANM", 23));

        emp_adapter=new EmployeeAdapter(MainActivity.this, emp_list);
        mListView.setAdapter(emp_adapter);

//      mListView.setAdapter(new ArrayAdapter<String>(this,
//                android.R.layout.simple_list_item_1,
//                mStrings));
        mListView.setTextFilterEnabled(true);
        setupSearchView();


    }
     private void setupSearchView() 
     {
            mSearchView.setIconifiedByDefault(false);
            mSearchView.setOnQueryTextListener(this);
            mSearchView.setSubmitButtonEnabled(true); 
            mSearchView.setQueryHint("Search Here");
        }

        @Override
