i have a viewflipper like below

   <ViewFlipper
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/ViewFlipper">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/aatrox"/>

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ahri"/>

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/akali"/>

    <ImageView
