resized parameters I can't use them to position my progress bar. Is there a
method in the main UI thread or inside my ImageView subclass that I can use
for that purpose?

Hi,
I am running an animation of a spinning star and I would like to add
some fade-in/fade-out effects. I am loading the animation in Java by
making the AnimationDrawable objects, and adding the bitmaps as frames
and then setting it to an ImageView using setBackgroundDrawable. I

I am sorry but I don't get this one. Dpi is screen density as far as I
understood... DPI- dots per inch... so the number of pixels on a inch
area on the screen. So isn't it screen density?

That in deed is a nice approach. I wasn't aware that android has such

but I guess a ring is also acceptable. But can you give me a hint how

Hmm actually I didn't though about using canvas and arcs - seems like
a good idea. I was thinking about using image animations but was

per second and I assume 15s so the animation would need 60 images. And
