導航抽屜不顯示，但仍然打開

Question

我正在使用Nutiteq SDK，它包含一個MapView，並且正在嘗試使用導航抽屜。我遇到的問題是每當我從左側滑動或單擊圖標打開抽屜時都不會打開，但我無法移動地圖，直到我將抽屜滑回或再次單擊圖標。這使我相信抽屜正在打開，但沒有顯示。這是我的MainActivity.java和activity_main.xml中：

MainActivity.java

public class MainActivity extends Activity { 

private MapView mapView; 
private LocationListener locationListener; 
private GeometryLayer locationLayer; 
private Timer locationTimer; 

private String[] drawerListViewItems;

private ActionBarDrawerToggle actionBarDrawerToggle; 

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

    setMap(); 

    // get list items from strings.xml 
    drawerListViewItems = getResources().getStringArray(R.array.items); 

    // get ListView defined in activity_main.xml 
    drawerListView = (ListView) findViewById(R.id.left_drawer); 

    // Set the adapter for the list view 
    drawerListView.setAdapter(new ArrayAdapter<String>(this, 
       R.layout.drawer_listview_item, drawerListViewItems)); 

    // App Icon 
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 

    actionBarDrawerToggle = new ActionBarDrawerToggle(
      this,     /* host Activity */ 
      drawerLayout,   /* DrawerLayout object */ 
      R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */ 
      R.string.drawer_open, /* "open drawer" description */ 
      R.string.drawer_close /* "close drawer" description */ 
      ); 

    // Set actionBarDrawerToggle as the DrawerListener 
    drawerLayout.setDrawerListener(actionBarDrawerToggle);

    // just styling option add shadow the right edge of the drawer 
    drawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);

我試圖用相同的Android抽屜示例應用程序，並與MapView的替代ImageView的。這對我來說很好，請看下面的截圖。也許問題是你把MapView直接放到主佈局上？請通過示例應用中的片段來嘗試。
