Hello guysngirls! :) Lately I've started to implement my first livewallpaper.
Basically it just fades one bitmap into another by reducing alpha of one image and increasing alpha of another (while drawing). Bitmaps are not very small, 800x480 in size. Currently the drawing is done by continuously posting a Runnable with a call to a drawFrame() function, once in a 1000/25 msecs - just as suggested by a livewallpaper sample from SDK samples. But I notice that the transitions are somewhat "step-like" - not very smooth. I think it can be smoother. The question is this: can this be due to a posting overhead? Would It get smoother if I would implement drawing in a separate thread? Then it would run on its own, all the time, and call drawFrame(). Also, is this acceptable for a live wallpapers? I have a game in which I use the paint thread to draw on a SurfaceView, just as I described above, and i have got a good performance :) Thanks in advance, Dmitry. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
