Or addGestureFrameLayout: 

<com.alexvasilkov.gestures.views.GestureFrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- GestureFrameLayout can contain only one child -->

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
