Use collapsing Toolbar layout for your requirment.

<android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsingToolbarLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:contentScrim="?attr/colorPrimaryDark"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scaleType="centerCrop"
            android:src="@drawable/abcd"
            app:layout_collapseMode="parallax"
            app:layout_collapseParallaxMultiplier="0.7" />

        <android.support.v7.widget.Toolbar
            android:id="@+id/mtool"
            android:layout_width="match_parent"

You can do that with android material design and make the AppBar collapse on scroll.Also add this attribute to your listView

app:layout_behaviour="@string/appbar_scrolling_view_behavior"
