Android - animated views

I started learning Android for 6 months more or less, so I already know the important part of layouts, but animations still be the dark part for me. I never learned how they work, because in my mind there is lot of ways of animating a view. Actually, I know that you can use ScaleAnimation class, but it still very basic, or use xml properties that I don't know.

Can anybody explain to me how to animate a view and the differents ways to do it?

Thanks in advance
