Hi Rodrigo: I asked this same question ages ago and never got an answer. In the end, I concluded the built-in animation machinery cannot handle a case where the bitmap is longer than the view.
I wound up not using any of the built-in animation stuff and just blitted raw bitmaps in a custom view. (Except I did have my implementation take Interpolators and work in parametric [0, 1] time, so at least I got free ease-in and ease-out effects.) I'm doing all this in the regular view hierarchy (no surface view or anything) on the main thread. No performance problems to report at speeds up to 20 FPS. -- Ward >HI, > >What is the best way to implement scrolling text (with behavior >similar to that of HTML tag 'marquee')?? > >I've been trying to do this using TextViews + Animations but I'm >having troubles primarily because of sizing issues.
