Android Hierarchical Navigation

I'm trying to get an example or a starting reference on how to develop a drill down structure. The best example I can give is, how Android navigates through it's own folder structure. Here is a screenshot to illustrate my point:

enter image description here

Some things I would like to point out:

Could someone please point me in the right direction. Many thank in advance!!

To those you are wondering how I managed this, I basically call the same activity, just with the parent ID (which will be located within the bundle). This way I can fill the ListView with the parent ID provided and let my BaseAdapter sort out which UI to display.

I don't know if the was the best way of doing it, but it worked for me.

Kind regards,

IMO, technically there is no limit on the structure depth. But for the sake of design, good user interaction with the app as well as for codes maintenance, I suggest 3 to 5 level deep is enough. If you must go further than that perhaps you should re-design the app.

And you may also use breadcrumb to improve structure visibility. http://developer.android.com/reference/android/app/FragmentBreadCrumbs.html
