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="sccs.android.com.userinformation.HomeScreen">

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fitsSystemWindows="true"

        app:layout_scrollFlags="scroll|exitUntilCollapsed">
        <ImageView
            android:id="@+id/header"
            android:layout_width="match_parent"
            android:layout_height="match_parent"

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:gravity="top"

            app:layout_collapseMode="pin"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>
    </android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>

<android.support.v7.widget.RecyclerView
    android:layout_below="@+id/appbar"
    android:padding="10dp"
    android:id="@+id/my_recycler_view"
    android:scrollbars="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>


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

推荐答案

如@shijil所示.

As @shijil showed.

您需要将此属性添加到R​​ecyclerView(或您要作为其内容父级的任何框架):

You need to add this attribute to the RecyclerView (or any frame you want to have as the parent in your content):

app:layout_behavior="@string/appbar_scrolling_view_behavior"

这将是您的RecyclerView的代码(除了app:layout_behavior属性之外，您无需添加其他任何内容):

This would be your RecyclerView's code (You don't need to add anything else besides the app:layout_behavior attribute):

<android.support.v7.widget.RecyclerView
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:layout_below="@+id/appbar"
    android:padding="10dp"
    android:id="@+id/my_recycler_view"
    android:scrollbars="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>
