Put an arrow in the viewPager indicating to pass the photo

I'm using this viewPager to make a sort of gallery

 <android.support.v4.view.ViewPager
    android:id="@+id/galeria"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="40dp"
    />

I'm wondering if there's any way I can put this arrow to indicate that you have more photos
