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

Example:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

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