OK, this is part of my code, very simple: public boolean onTouchEvent(MotionEvent event) {
int count = event.getPointerCount(); ... int action = event.getAction(); int x = (int) event.getX(); int y = (int) event.getY() - absize; ... return true; } The absize is the current Action Bar height I am using. If without it, event.getY() will works fine in Android 1/2 devices, but on my HTC Jetstream (Honeycomb) and Galaxy Note, the Y value is offset by 56 pixels (which is my current absize). In both cases, I tested them with finger and stylus. Ideally it should be like what you say, event.getY() just works, but it does not. My minimum SDK level is 7 as I intend to support older devices but allows for Action Bar on Android 3/4 devices. I think this might be the issue (ie, getY() will works fine if my minimum Android version supports Action Bar by default). 在 2012年7月4日星期三UTC+8上午9时30分57秒,Dianne Hackborn写道: > > What you are claiming is happening is... well, you probably need to > explain more. > > If you have an action bar, then by default your content is placed below > it, and the coordinate space of events received by the view will be > relative to where it is placed.
