/**
 * Perform animation and selection on the current ItemView.
 * <br/><br/>
 * <b>IMPORTANT NOTE!</b> <i>setActivated</i> changes the selection color of the item
 * background if you added<i>android:background="?attr/selectableItemBackground"</i>
 * on the row layout AND in the style.xml.
 * <br/><br/>
 * This must be called after the listener consumed the event in order to add the
 * item number in the selection list.<br/>
 * Adapter must have a reference to its instance to check selection state.
 * <br/><br/>
 * If you do this, it's not necessary to invalidate the row (with notifyItemChanged): In this way
 * <i>onBindViewHolder</i> is NOT called on selection and custom animations on objects are NOT interrupted,
 * so you can SEE the animation in the Item and have the selection smooth with ripple.
