推荐答案

您试图确定什么的电流的图像上的的ImageView ，以便将其切换到其他的形象呢？

Are you trying to determine what the current image is on the imageview, in order to change it to some other image?

如果这是如此，我建议做的一切使用code，而不是XML。

If that's so I suggest doing everything using code instead of xml.

即。使用 setImageResource（）初始化时设定的初始的图像和跟踪资源的id 正在使用某个地方在code。

i.e. Use setImageResource() to set the initial images during initialization and keep track of the resource ids being used somewhere in your code.

例如，你可以有 imageviews 阵列与 INT 的相应的数组包含资源ID 每个的ImageView

For example, you can have an array of imageviews with a corresponding array of int that contains the resource id for each imageview

然后，只要你想通过数组来改变形象，环路，看到了id是什么。

Then, whenever you want to change the image, loop through the array and see what the id is.
