Is there any particular reason you are using a frame-based animation? I haven't done any frame-based animations, but I know you could accomplish the same (or very similar) thing using an AnimationSet defined in XML.
You could then specify a rotation to the image as well as a fade in/out with alpha... As a simple example, this could go in res/anim and be called something like spin_fade_in.xml: <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android";> <alpha adroid:fromAlpha="0.0" android:toAlpha="1.0" android:duration="500" android:startOffset="0" /> <scale android:fromXScale="1" android:toXScale=".85" android:fromYScale="1" android:toYScale=".85" android:duration="100" android:startOffset="0" android:pivotX="50%" android:pivotY="50%" /> <rotate android:fromDegrees="0" android:toDegrees="360" android:pivotX="50%" android:pivotY="50%" android:duration="500" android:startOffset="0" /> <scale android:fromXScale=".85" android:toXScale="1" android:fromYScale=".85" android:toYScale="1" android:duration="100" android:startOffset="400" android:pivotX="50%" android:pivotY="50%" /> </set> Thanks, Justin Anderson MagouyaWare Developer http://sites.google.com/site/magouyaware On Tue, Mar 20, 2012 at 10:24 AM, Serdel <[email protected]>wrote: > Hi, > > I am running an animation of a spinning star and I would like to add > some fade-in/fade-out effects.
