我一起使用CollapsingToolbarLayout,RecyclerView和SwipeRefreshLayout:

XML:

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

        android:fitsSystemWindows="true"
        app:expandedTitleMarginStart="48dp"
        app:expandedTitleMarginEnd="64dp"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <ImageView
            android:id="@+id/toolbar_image"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scaleType="centerCrop"
            android:fitsSystemWindows="true"
            app:layout_collapseMode="parallax" />

        <include
            layout="@layout/activity_main_toolbar"/>

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

    <android.support.v4.widget.SwipeRefreshLayout

            android:layout_height="match_parent"
            android:scrollbars="vertical" />
    </android.support.v4.widget.SwipeRefreshLayout>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/floating_action_button"
