協調器佈局，摺疊工具欄不折疊

工具欄在滾動時不折疊。我甚至使用了嵌套滾動視圖。雖然它崩潰時，我不使用 應用程序：layout_behavior =「@字符串/ appbar_scrolling_view_behavior」。但後來LinearLayout的內容不可見。這裏是我的代碼協調器佈局，摺疊工具欄不折疊

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:fitsSystemWindows="true" 
tools:context="aman.com.quickcars.activities.CarInfoActivity"> 

<FrameLayout 
    android:id="@+id/main_container" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    > 
    <android.support.v4.widget.NestedScrollView 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:fillViewport="true"> 

     <LinearLayout 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      > 

      <TextView 
       android:id="@+id/text" 
       style="@style/TextAppearance.AppCompat.Large" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:layout_gravity="center" 
       android:gravity="center" 
       android:text="this is a text view" /> 



     </LinearLayout> 

    </android.support.v4.widget.NestedScrollView> 

</FrameLayout> 


<android.support.design.widget.AppBarLayout

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

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_car_info); 

    toolbar= (Toolbar) findViewById(R.id.image_toolbar); 
    setSupportActionBar(toolbar); 
    collapsingToolbarLayout= (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar); 
    collapsingToolbarLayout.setTitle(retrievedList.get(pos).getName()); 
    collapsingToolbarLayout.setExpandedTitleColor(getResources().getColor(android.R.color.transparent)); 
}

您必須刪除FrameLayout並保持NestedScrollView爲CoordinatorLayout
