有一个ImageView的一个onImageChangedListener（）？

Is there an onImageChangedListener() on a ImageView?

我所需要的事件时，图像被从ImageView的改变。

I need the event when the image is changed from the ImageView.

推荐答案

检查ImageView的code中的grep code。你不知道它被更改或重绘时。这是因为你setImageDrawable（）后，ImageView的将无效。这时，图像不正常改变，直到OnDraw中被调用。

Check the imageview code in grepcode. You don't know when it is changed or redrawn. It is because after you setImageDrawable(), imageview will invalidate. At this time, the image IS NOT CHANGED correctly until ondraw is called.

总之，你为什么想知道onimagechangedlistener？

Anyway, why do you want to know the onimagechangedlistener?
