From: http://www.r-base.net/archives/442 In Android UI development, if you use XML to configure layout, we can easily implement compatibility issues with different resolutions (using dip units ). however, if you cannot use XML to configure layout in a game, it will be a lot of trouble if we are compatible with different resolutions. some coordinate calculations can also change the units of dip to pixels. when I was developing a hamster game, I found that the text was hard to calculate the width.
