Ripple effect is not going above the ImageView

I have a CustomListView where I'm showing some text and getting an image displayed using Picasso's library. I created a xml file inside the drawable folder and for drawable-21 folder for the Ripple Effect but for some reason the effect is not going above the ImageView.

Here's my files:

drawable: listview_item_background.xml

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

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle" >
            <solid
                android:color="#ffdadada"/>
        </shape>
    </item>
    <item>
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle" >
            <solid
                android:color="#ffffff"/>
        </shape>
    </item>
</selector>

drawable-v21: listview_item_background.xml

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="#ffdadada">
    <item android:drawable="@android:color/white"/>

          }
      });

      return rowView;

  }
}

That's how I display the ImageView.

Could you help me please?

What is ripple effect in Android?

The touch feedback in Android is a must whenever the user clicks on the item or button ripple effect when clicking on the same, gives confidence to the user that the button has been clicked so that they can wait for the next interaction of the app.

What is ripple color Android?

As you've noticed, ripples are used subtle indications of touch feedback, hence why they do not use colorPrimary or colorAccent by default. This is consistent with the changes made in Android 4.4 (Kitkat) which made the default selector colors neutral by default.

I managed to fix the issue without an extra layout in my case.:

    <CardView ...>
       <RelativeLayout
           ...
           android:clickable="true"
           android:focusable="true"
           android:foreground="?attr/selectableItemBackground">

           <ImageView .../>
        </RelativeLayout>
     </CardView>

Few days back I was also facing same issue. I solved my issue by wrapping ImageView inside FrameLayout and applying android:foreground property on FrameLayout. You also have to set android:clickable property of FrameLayout to true or should set onClickListener to FrameLayout.

Please check my answer in following thread in following link.

Let me know if it helps.
