looking for tutorial to design nice GUI in android studio (Eclipse)

hi , i start to use Eclipse and android sdk to create an company info app

i search and find some nice cool tutorial about basic instruction of create app in android studio and explain options and menus

but on all of them use default buttons , list styles , menus and only talk about basic of layout design

so i can only create a very basic app with default android GUI

i really need some tutorial about Create advance and responsive GUI layout and graphics for my app , work with both portrait and landscape mode and graphic not lose quality on Tablets or big size phone

lynda , udemy , video2brain and all other video tutorials about create android app doesn't have something like this and its really strange !
