How add item transparency inside RecyclerView when it's out of list border?

Question

How make RecyclerView item disappear smoothly when it is going out of list border? See image below. All possible solutions highly appreciated!

Note: Solution with View above RecyclerView which has gradient background (shadow imitation) does not work well because I have gradient background on screen and it is difficult to match that "shadow" view background to screen background and it look like that:

So, works like shadow not like disappearance.

UPDATED: Got the second screen with following background:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
    <gradient
        android:type="linear"
        android:startColor="#FF14141d"
        android:endColor="#0014141d"
        android:angle="270"/>
</shape>

Here is original screen background

if you want to fade edges, you can use:

 <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:requiresFadingEdge="vertical" <-- this line
        android:fadingEdgeLength="150dp" <-- this line, the height of fade
