By default getChildCount returns zero, and thus the ExpandedListView produces no children until it's overridden.

See that you haven't overidden this with a bad value, such as replacing the value there with another constant. You should put a function here that returns the correct number of children given position as a parameter.

override the method getChildView properly. It will resolve the issue and also make proper initialization of child arrays for each group item.
