ImageView extends View

where as

ImageButton extends ImageView.

ImageView is used set icons from different sources where as ImageButton ,displays a button with an image (instead of text) that can be pressed or clicked by the user .

Memory allocation of both the views depends on the image src else there is not significance difference in terms of memory .

ImageButton is-a ImageView which essentially just supplies a default style for the image button, and the image button default style supplies a button background drawable.

With everything else held constant, changing an ImageView without a background to an ImageButton consumes more memory since the background takes up some. If you're concerned, use a memory analysis tool to find out whether the difference is significant.

Which one to use: Use ImageButton if you want an ImageView with button styling. If you just want to display an image, use ImageView.
