You should check Lunar Lander from SDK samples.
The main idea is to get SurfaceHolder and pass it to separate thread.
This thread should update the screen in it's run() method.
The contents of the run method may look like this:
while (threadRun) {
Canvas c = null;
try {
synchronized (surfaceHolder) {
c = surfaceHolder.lockCanvas();
//Your drawing code goes here
}
} finally {
if (c != null) {
surfaceHolder.unlockCanvasAndPost(c);
}
}
}
