Hi all,

I Have drawn a set of images(balls) on a SurfaceView. Now am trying to make the image(ball) i touch to disappear. Am having those images in a collection. Am not understanding how to generate touch event on individual image. Can any one provide
some help on this?

Thank You

推荐答案

-找出触摸事件的位置(Clickedy [ ^ ])
-检查该位置是否有物体-如果是这样，请识别它.
-杀死它.

能够识别ID上的图形对象将很有帮助-字符串可能很好，UUID也可以解决问题，甚至还可以简单地计算对象(如果缺少1个对象之间的情况，会发生什么情况?)

- figure out the position of the touch event (Clickedy[^])
- check whether there is an object located at that position - if so identify it.
- kill it.

It would be helpful to be able to identify the graphical object on a ID - a String could be fine, an UUID would do the trick too and it might even be able to simply count the objects (what happens when 1 object in between is missing?)
