What happens if only fitwidth is set in imageview?

If only fitWidth is set, image's view width is scaled to match and height is unchanged; If only fitHeight is set, image's view height is scaled to match and height is unchanged; If both are set, the image view is scaled to match both.
Besides, what's the difference between Fit _ Center and imageview?
The result is the same as with fit_center. Because we use adjustViewBounds and we set the height, the ImageView has the same aspect ratio as the image and the image is perfectly aligned. In this case the difference with fit_center is the image is now being aligned to the right and bottom of the ImageView.
Also Know, why does adjustviewbounds not affect the image size? In this case having adjustViewBounds or not doesn’t make a difference. The reason is because the image is scaled uniformly so it maintains the aspect ratio but because the image will be equal or larger than the ImageView the width of the ImageView is going to be larger in both cases.
In fact, why do imageviews have a larger width than imageview?
The reason is because the image is scaled uniformly so it maintains the aspect ratio but because the image will be equal or larger than the ImageView the width of the ImageView is going to be larger in both cases. This result is also the same as using center without adjustViewBounds.
