I need to do an effect similar to that of ZenUI in call, that the photo with circle emits waves (zoon from below) as can be seen in the video http://youtu.be/niWK2U71t28?t=1m38s

Does that help a lot because I don’t even know where to start the research!

I’m using Android Studio with the image already with border and in Circle:

<br.CircularImageView
        android:layout_width="150dp"
        android:layout_height="150dp"
        android:id="@+id/ivFotoEncontre"
        android:src="@drawable/photo_defalt"
        android:layout_margin="10dp" />

You can create several ImageView's, each with a different radius from the other and with shades alpha also different. That way, when receiving a call, you can make an animation that plays with visibility creating a "wave effect".

    Only complementing, which can also be used Framelayout to overwrite the Imageviews.

    The idea is not bad! I would also do so if it were the case, centralizing Imageview’s alpha’s in the main.
