Multilevel listview on android with mysql data from different tables

I want to implement a multilevel listview app in android that populates data from a MySQL database. As it is, I have searched low and high through the Internet to find material to learn from, but to no avail. I am a tenderfoot in android programming; I would really appreciate it if anybody who has experience in doing a multilevel listview app using data from MySQL could share their knowledge with me. And if anybody could direct me to tutorials related to my problem, that is welcome too.

I see the sample from androidhive.info/2012/10/android-multilevel-listview-tutorial/, but i need that the json array no to be static, i must be a select from diferent tables. I know how to display on a list one json but i dont have any idea of the php code to make the other levels and how to conect them.
