Represent Graphically a Tree

 What would be the best way to represent a data tree graphically?

I've thinked to use a multi level TextView, but these levels are
implemented into ListView or I must implement them into my code?

Like a File Manager, wich the filesystem is the tree structure and the
directory and files are the items. I want to navigate inside my tree
pressing the items to go to the next level and back button to go back
to the previous tree level.

Is there something to use out of the box for doing this?

Thanks

 Expandable ListView can only have 2 levels I think.

 Yes. But it's built on top of ListView, which is very well documented. Since
the OP already has a tree data structure, it should be quite easy to build
something similar, but with an arbitrary number of levels (if needed).

Extend it and add your own functionality.

You probably don't want to nest too deeply anyway considering the screen
limitations on mobile devices.
