折叠工具栏并在滚动条上隐藏TabLayout

Question

I want to collapse Toolbar using CollapsingToolbarLayout and then move TabLayout under the Toolbar. Here is my code

<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
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.support.design.widget.CollapsingToolbarLayout
        android:layout_width="match_parent"
        android:layout_height="122dp"
        android:id="@+id/collapsingToolbar"
        app:expandedTitleMarginStart="56dp"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <android.support.v7.widget.Toolbar
            android:layout_height="?attr/actionBarSize"
            android:layout_width="match_parent"
            android:id="@+id/toolbar"
            app:layout_collapseMode="pin"/>

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

    <android.support.design.widget.TabLayout
        android:layout_height="?attr/actionBarSize"
        android:layout_width="match_parent"
        android:layout_gravity="bottom"
        android:id="@+id/tabLayout"
        android:background="@color/default_green"
        app:layout_scrollFlags="scroll"/>

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

<android.support.v4.view.ViewPager
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/viewPager"
    app:layout_behavior="@string/appbar_scrolling_view_behavior/>
</android.support.design.widget.CoordinatorLayout>

Now I have collapsing Toolbar, but I don't know how to scroll off TabLayout under the collapsed Toolbar. I found this solution , but in such case Toolbar is not collapsing.

如果我能正确理解您的话，那么说“滚动折叠的工具栏下的TabLayout”是指将折叠的工具栏下的TabLayout隐藏起来，那么您应该将属性app:layout_scrollFlags更改为app:layout_scrollFlags ：

app:layout_scrollFlags="scroll|enterAlways"
