Q:

Tree List View In Android

I am trying to do a tree list in android using this project library.
First: I cannot import it in Eclipse. I am getting the following error:
[2014-01-15 14:58:18 - tree-view-list-android] Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties.

even if I try go to the project properties I am getting the same error and I cannot open it.
Second: I found different version on the project HERE but there is no documentation at all.
I was wondering if there is another approach to complete the task. I checked that I can accomplish it using so called ExpandableListView but they can handle only up to two levels and I want more. 
Any suggestions???
Thank you in advance!!!

A:

I've implemented it with Custom ListView, here's a link where I've posted example of my implementation:
