How do I scroll the background image on an ACTION_MOVE
event?
Here is my code used to draw the background image:
void drawFrame() {
final SurfaceHolder holder = getSurfaceHolder();
Canvas c = null;
try {
c = holder.lockCanvas();
if (c != null) {
c.drawBitmap(myBg, 0, 0, mPaint);
}
} finally {
if (c != null) holder.unlockCanvasAndPost(c);
}
// Reschedule the next redraw
mHandler.removeCallbacks(mDrawAnim);
if (mVisible && mAnime) {
mHandler.postDelayed(mDrawAnim, 50 );
}
}
