Ripple effect weird behavior in ListView

I have implemented the ripple effect for each item inside the ListView by using <ripple> element. I got the desired ripple effect when I touch (select) on each item in the ListView. But when I scroll the ListView and then select any item again the ripple disappears very fast (almost unnoticeable). I don't know why the ripple appears nicely on some ListView items and very weird on some.

My customized ripple layout is shown below (ripple_background.xml)

<ripple
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="@color/light_black_overlay">
    <item>
        <shape
            android:shape="rectangle">
            <solid android:color="@android:color/background_light" />
        </shape>
    </item>
</ripple>

Layout for the item inside ListView

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="48dp"
    android:minHeight="?android:listPreferredItemHeight"
    android:orientation="horizontal"
    android:background="@drawable/ripple_background"> <!--My ripple layout-->

    <TextView
        android:id="@+id/someText
        android... />

    <ImageView
        android:id="@+id/someImage
        android... />

</RelativeLayout>

Has anyone faced this kind of weird ripple effect inside your ListView? Any idea if the ListView's recycling mechanism has to do something with this? Thank you.

Instead of passing ripple effect to each item of your list try this:

<ListView
        android:id="@+id/yourListView"
        ...
        android:listSelector="@drawable/ripple_background" />
