This is a screenshot of the output on the android emulator. You can see that only the foodTasks are being shown on all categories. I can't seem to figure out why...

From what I can tell the Lists are all populated properly I added code to make sure at one point and they all have the appropriate data in them. They just aren't being added into the HashMap for some reason. In Fact for the Construction and Casino categories the app crashes and says they are null.

Edit: ExpandableListAdapter Class for more error checking.

Answer 1

I had a typographical error in file ExpandableListAdapter.java at line 80.
I accidentally put

final String childText = (String)getChild(1,i1);

instead of

final String childText = (String)getChild(i,i1);

Thanks for all of your help guys. This is solved.
