The objects aren't equal and no comparator is available to handle it. Second, it isn't that easy because the image the button uses has lost the meta data, so it doesn't know where it came from. You could load the image from resource and compare the images. Some links are included. But I guess you want to simply check some state and act accordingly. In that case it would be best to keep track of state using an enum or numeric value. You can use that to show the image accordingly or handle whatever needs to be done at a certain state.

Good luck!
