It is a real problem I noticed even for quality developers. The way designers design the apps sometimes they require the eye of an designer too who can code. As Stanley mentioned it not possible for any tool convert PSD to XML flawlessly as each design differs their gestures structures are different for different apps. To learn Refer to the Tutorialspoint or Android Dev s . They have some good resources to start with. To get work done with Professionals There are some Professional designers like people at Redelegant Design studio who design beautiful App UI and also help you to convert App XML from PSD or AI files (App design files).
