导航视图，列表视图和所选项目存在问题

Question

我的android示例应用程序有问题。我有一个带有ListView菜单的NavigationView。我无法将选中的项目标记为选中。我尝试了setItemChecked但什么都没有：（

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemClickListener {

 private DrawerLayout dl;
 private ActionBarDrawerToggle t;
 private NavigationView nv;
 private ListView listview;
 private List < String > markets;

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

  dl = (DrawerLayout) findViewById(R.id.activity_main);
  listview = (ListView) findViewById(R.id.listview);
  t = new ActionBarDrawerToggle(this, dl, R.string.Open, R.string.Close);

  dl.addDrawerListener(t);
  t.syncState();

  getSupportActionBar().setDisplayHomeAsUpEnabled(true);

  getSupportActionBar().setElevation(0);
  markets = new ArrayList < String > ();
  markets.add("Sample");

  ArrayAdapter < String > adapter = new ArrayAdapter < String > (this, android.R.layout.simple_list_item_1, markets);
  listview.setAdapter(adapter);
  listview.setOnItemClickListener(this);
  nv = (NavigationView) findViewById(R.id.nv);
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
  if (t.onOptionsItemSelected(item)) return true;
  return super.onOptionsItemSelected(item);
 }

 @Override
 public void onItemClick(AdapterView << ? > adapterView, View view, final int position, long l) {

  Fragment fragment = null;
  Class fragmentClass = null;
  if (position == 0) fragmentClass = FirstFragment.class;
  else fragmentClass = SecondFragment.class;
  try {
   fragment = (Fragment) fragmentClass.newInstance();
  } catch (Exception e) {
   e.printStackTrace();
  }

  FragmentManager fragmentManager = getSupportFragmentManager();
  fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();

  // Highlight the selected item has been done by NavigationView
  setTitle(adapterView.getItemAtPosition(position).toString());
  dl.closeDrawers();
 }
}
