How To Properly Set Elevation Value To Recyclerview?

I am working on grid layout using recyclerview in android. The grid occupies a portion of the screen and has a shadow. To get the desired shadow effect I am using an elevation valu

Solution 1:

I found the answer after a little bit of searching from here. The problem was the transparent background. Elevation works with only non-transparent backgrounds on views. To fix it we should set android:outlineProvider="bounds" on the view and android:clipToPadding="false" on the view's parent.

Hope it helps someone.

Solution 2:

For Lollipop and you can use the android:elevation property but below lollipop versions you have to give custom shadow so refer the below code for shadow

card_background.xml

<?xml version="1.0" encoding="utf-8"?><layer-listxmlns:android="http://schemas.android.com/apk/res/android"><item><shapeandroid:shape="rectangle"><solidandroid:color="#CABBBBBB"/><cornersandroid:radius="2dp" /></shape></item><itemandroid:left="0dp"android:right="0dp"android:top="0dp"android:bottom="2dp"><shapeandroid:shape="rectangle"><solidandroid:color="@android:color/white"/><cornersandroid:radius="2dp" /></shape></item></layer-list>

Give this file as a background to your recyclerview inflater file it will work fine.

Solution 3:

Just set below three property in your recyclerview

android:outlineProvider="bounds"android:background="@null"android:elevation="2dp"

Solution 4:

The android:elevation does only apply shadows on devices which are running Lollipop or later. If you want to suppot older devices, you have to create a shadow yourself.
