However, in many apps the image only changes after some user event, so redrawing the same image over and over again seems a big waste of CPU power. How could we implement some Invalidate() / OnDraw() scheme, where drawing only takes places after a user event? (But still use a second thread to keep the load from the main GUI thread...)Hermannhttps://www.blogger.com/profile/02763520358960121672noreply@blogger.comtag:blogger.com,1999:blog-2865777313825124004.post-28793202881070472092012-04-21T18:20:58.091-07:002012-04-21T18:20:58.091-07:00what about drawing on top of a surfaceview backgro...what about drawing on top of a surfaceview background image, like with drawRect.Firebreatherhttps://www.blogger.com/profile/08672880457083843230noreply@blogger.comtag:blogger.com,1999:blog-2865777313825124004.post-62747153014797685512012-03-04T15:43:03.105-08:002012-03-04T15:43:03.105-08:00hello,,
