Answer 1

Had the same problem as Jiang:

I have to set the attributes to the layout-file, which is inflating the RecycleView.

My Main-Layout: (Don't add the properties here!)

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

<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="match_parent">


<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:scrollbars="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

</RelativeLayout>

My RecycleViewAdapter:

            View v = inflater.inflate(R.layout.list_center_item, parent, false);

My list_center_item.xml (Add the properties here!)

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


<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"


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

Answer 2

You have to add following lines in the layout that you are using under CardView

android:clickable="true"
android:focusable="true"
android:background="@drawable/my_ripple"

Example

<android.support.v7.widget.CardView android:layout_height="wrap_content"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
android:background="@drawable/my_ripple">

Answer 3

Assuming you are using Material/Appcompat theme and Lollipop,I got this to work by making the CardView have the following attributes:

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

Answer 4

None of the above answers worked for me or was either too complicated.

Then I realized I had to set the following properties in THE RECYCLERVIEW ADAPTER LAYOUT.

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

Then I got it to work.
