In this application, I noticed that if you click on an element and hold it, the element is painted in a grayish color, making it clear to the user that he clicked on it. As in ListView. How to do also? And then I press / hold on the element, but somehow it is not clear. In ListView, too, was painted in a grayish color.

enter image description here

Markup

LinearLayout in which you have view elements set the background:

 android:background="?android:selectableItemBackground" 
 <android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/cardView" android:layout_width="match_parent" android:layout_height="wrap_content" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:background="?android:selectableItemBackground" >
  • I did this, but by clicking on the item on the list it is not noticeable that the background somehow changes - Scorpion
  • Show the markup code, I just write the application, also implemented, it works great for me. - McDaggen
  • In question added - Scorpion
  • It worked. It turns out that LinerLayout added the attribute - Scorpion

If you have your own adapter for ListView, then handler will tell it via setOnItemLongClickListener, within which you can tint, animate or something else to do with your views.
