Ripple effect over a RecyclerView item containing ImageView

android, android-recyclerview, ripple

Solution

add below code to your parent layout

android:clickable="true"
android:focusable="true"
android:background="?attr/selectableItemBackground"

if you want custom ripple effect add this ripple_custom.xml in your drawable-v21

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

    <item
        android:id="@android:id/mask"
        android:drawable="@color/windowBackground" />
</ripple>

to support older version add ripple_custom.xml in drawable

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape android:shape="rectangle">
            <solid android:color="@color/colorHighlight" />
        </shape>
    </item>
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@android:color/transparent" />
        </shape>
    </item>
</selector>

Problem

I have a `RecyclerView` that expands the following grid item : ``` <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="@dimen/children_tile_border" android:layout_marginTop="@dimen/children_tile_border" android:clickable="true" android:focusable="true" android:background="?selectableItemBackground" tools:ignore="RtlHardcoded"> <com.example.app.ui.widget.SquareImageView android:id="@+id/child_picture" android:layout_width="match_parent" android:layout_height="wrap_content" android:visibility="visible" android:layout_alignParentBottom="true"/> <LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="68dp" android:background="@color/tile_text_background" android:gravity="center_vertical" android:layout_alignParentBottom="true"> .............. </LinearLayout> </RelativeLayout> ``` But the ripple effect doesn't appear unless I set the `SquareImageView's` visibility to invisible. It seems the ripple effect is drawn below the `SquareImageView`. How can I can I make it drawn over the `SquareImageView`?
