My question is, can I prevent the bogus onScroll? Here's the code: @Override public boolean onTouchEvent(MotionEvent event) { // Log every event. Log.d(TAG, Here.at() + String.format(

问题 I have a very simple test app with a custom component MyView.java - which displays a scrollable and scalable image (representing a board in a Scrabble-like word game): 1) In my scale listener I adjust the scale factor: public boolean onScale(ScaleGestureDetector detector) { mScale *= detector.getScaleFactor(); // XXX how to adjust mOffsetX and mOffsetY ? XXX constrainZoom(); constrainOffsets(); invalidate(); return true; } 2) And then in the drawing method of my custom component I apply the
