There are basically two type of animations:
View Animation:
With View Animation you can perform a series of simple transformations (position, size, rotation, and transparency) on the contents of a View object
Drawable Animation:
Drawable animation lets you load a series of Drawable resources one after another to create an animation. This is a traditional animation in the sense that it is created with a sequence of different images, played in order, like a roll of film
The above two links have enough examples to get you started.
