Android NavigationView抽屉不关闭

Question

实现NavigationView抽屉 - 我能够生成抽屉并看到它，但不能用滑动关闭它。此外，NavigationItemSelectedListener似乎没有正确设置，因为我无法检测项目上的点击事件。

MainActivity.java

private NavigationView navigationView; 
private DrawerLayout navDrawerLayout; 
private ListView navDrawerList; 
private ArrayList<NavDrawerItem> navDrawerItemList; 
private ActionBarDrawerToggle navDrawerToggle; 

    private void setupNavDrawer() { 
    this.navigationView = (NavigationView) findViewById(R.id.navigation_view); 
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() { 
     @Override 
     public boolean onNavigationItemSelected(MenuItem item) { 
      Utility.showDebugToast(String.valueOf(item.getItemId())); 
      if(item.isChecked()) { 
       item.setChecked(false); 
      } else { 
       item.setChecked(true); 
      } 
      navDrawerLayout.closeDrawers(); 
      return true; 
     } 
    }); 
    this.navDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
    this.navDrawerList = (ListView) findViewById(R.id.left_drawer); 
    this.navDrawerItemList = new ArrayList<>(); 
    this.navDrawerItemList.add(new NavDrawerItem("NAME", NavDrawerItemType.NAME)); 
    this.navDrawerItemList.add(new NavDrawerItem("Create Mesh", NavDrawerItemType.CREATE_MESH)); 
    this.navDrawerList.setAdapter(new NavDrawerAdapter(this, R.layout.drawer_item, R.id.drawer_tab_text, this.navDrawerItemList)); 

    this.navDrawerToggle = new ActionBarDrawerToggle(this, navDrawerLayout, R.string.accept, R.string.accept) { 

     @Override 
     public void onDrawerClosed(View view) { 
      super.onDrawerClosed(view); 
     } 
     @Override 
     public void onDrawerOpened(View view) { 
      super.onDrawerOpened(view); 
     } 
    }; 

    this.navDrawerLayout.addDrawerListener(navDrawerToggle); 
    navDrawerToggle.syncState(); 
}

为什么我不能滑动抽屉进出？

Answer 1

关于抽屉关闭行为，我预计这是关于你的activity.xml的结构。

作为每the guidance here：

要使用DrawerLayout，您的主要内容视图定位为与match_parent的宽度和高度的第一个孩子。在主内容视图之后添加抽屉作为子视图，并适当地设置layout_gravity。

所以这就是说，在你的情况下，你有一个内容部分和一个抽屉，DrawerLayout应该有两个孩子;首先是内容，然后是抽屉。在你的xml目前，DrawerLayout只有一个孩子，一切都在CoordinatorLayout。

请尝试移动NavigationView外CoordinatorLayout的让你的活动看起来是这样的：

<DrawerLayout> 
    <CoordinatorLayout> 
     content 
    </CoordinatorLayout> 

    <NavigationView> 
     drawer stuff 
    </NavigationView> 
</DrawerLayout>
