由 偶尔善良 提交于 2019-12-04 08:27:57
In my application, i am moving image around the screen by using onTouchListener . I have another two images in the same view. My problem is that, when the moving image, touches any of the other images, i need to perform a certain action (that means if images are intersected, then do something).
