问题
Say, for an ImageButton on screen A (240X320: ldpi) and screen B (720X1280: xhdpi), is it recommended to manually change the dp (layout-width and height) size of it in each unique layout resource file for various screens? Or, create scaled nine-patch bitmaps for each dpi size of the image, call it on the drawable resource file, and then set it as the src for the ImageButton?
To justify, here's what I mean: https://www.youtube.com/watch?v=OtsZbdbC370 ... Most likely, the video is outdated, correct?

It is entirely up to you if you want to change the layout width and height (in dp) of an imageButton. There is certainly nothing wrong with setting width and height of an imageButton or any UI element for that matter, in each unique layout resource file for various screens. Did you have specific code you wanted to get feedback about?
