当滚动<code>ListView</code>时，无法隐藏带动画的工具栏滚动ListView

Question

我想隐藏ToolBar。像this：

这是我的xml：

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:id="@+id/tabanim_maincontent" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <android.support.design.widget.AppBarLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> 

    <android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="?attr/actionBarSize" 
     android:background="@color/actionbar_bg" 
     app:popupTheme="@style/AppTheme.PopupOverlay" 
     app:layout_scrollFlags="scroll|enterAlways" > 

     <Spinner 
      android:id="@+id/spinner" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"/> 
    </android.support.v7.widget.Toolbar> 

    </android.support.design.widget.AppBarLayout> 

    <ListView 
     android:id="@+id/list_view" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior"/> 

</android.support.design.widget.CoordinatorLayout> 

而且这是我在Activity代码：

public class ToolBarTestActivity extends AppCompatActivity { 

private Toolbar toolbar; 
private ListView mListView; 

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

    toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
    getSupportActionBar().setDisplayShowTitleEnabled(false); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
    getSupportActionBar().setHomeButtonEnabled(true); 


    mListView = (ListView) findViewById(R.id.list_view); 

    final String[] catnames = new String[] { ... // 100 strings 
    }; 

    ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, catnames); 
    mListView.setAdapter(adapter); 

} 

}
