问题
I want to have more than one expandable list within a layout. It appears that an expandable list in a custom layout must have an id of "@id/android:list". So, how could I have more than one if they would need to have the same id? Thanks...

They don't have to have the @id/android:list ID - they only have to have that ID if you are using a ListActivity or ExpandableListActivity. Just use a normal Activity and give them unique IDs.
