There is a way to intercept touch events sent to a view: http://developer.android.com/reference/android/view/View.html#setOnTouchListener(android.view.View.OnTouchListener)
... and it should work with an ImageView and such. I'd also consider writing your own view subclass and handling the UI interaction completely within that view: http://developer.android.com/reference/android/view/View.html#onTouchEvent(android.view.MotionEvent) You could also subclass ViewGroup - or probably one of the layout classes, such as FrameLayout, and then use this: http://developer.android.com/reference/android/view/ViewGroup.html#onInterceptTouchEvent(android.view.MotionEvent) ... to direct events to this view or to enclosed views, if you wanted to do it that way. -- Kostya 25 января 2012 г. 22:08 пользователь darrinps <[email protected]> написал: > OK, so this is a good one. > > I need the ability to allow an image to be re-sizable (pinch zoom for > example) and scrollable (finger drag) yet still allow parts of that > image to be pressed and depending on which part is pressed, have a > different action take place. > > For example, suppose my image had four areas where each area (denoted > by []) can be selected like this: > > [][] > [][] > > If the user pinch zooms the thing it might look like this: > > [ ][ ] > [ ][ ] > > I thought about breaking the image up into areas and using image view > buttons but I am not so sure about scrolling the thing or zooming. > > So, is there any way to specify coordinates on an image and based on > where the user presses know what area they touched?
