如何实现Play商店折叠工具栏布局？

Question

*它不是collapsing toolbar layout like google play store 的重复

我想在recyclelerView向下滚动时向下滚动collapsingToolbarLayout，反之亦然如下.gif图像。

任何帮助将不胜感激。

我使用了不同的layout_scroll标志但它根本不起作用。

并且有xml布局：

    <?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"
      xmlns:tools="http://schemas.android.com/apk/res-auto"
      android:id="@+id/profileCoordinatorLayout"
      android:layout_width="match_parent"
      android:layout_height="match_parent">


     <LinearLayout
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:orientation="vertical"
       app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:background="@color/colorPrimaryDark" />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/list1"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    </LinearLayout>


     <android.support.design.widget.AppBarLayout
       android:id="@+id/appBarLayout1"
       android:layout_width="match_parent"
       android:layout_height="250dp"
       android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/profileactivity_collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:contentScrim="@color/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed"
        app:statusBarScrim="@color/colorPrimaryDark"
        app:titleEnabled="false">

        <android.support.v7.widget.Toolbar
            app:navigationIcon="@drawable/ic_menu_white"

            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

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

    </ir.unary.zhin.CAppBar>


    <android.support.design.widget.FloatingActionButton

Answer 2

使用此

<RelativeLayout 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:id="@+id/id_toolbar_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark">

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

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/main_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/id_toolbar_container">

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

            <android.support.design.widget.CollapsingToolbarLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:layout_scrollFlags="scroll|enterAlways">

                <android.support.design.widget.TabLayout
                    android:id="@+id/tab_layout"
                    android:layout_width="match_parent"
                    android:layout_height="?attr/actionBarSize" />
            </android.support.design.widget.CollapsingToolbarLayout>

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

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

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