I have a listview with tickboxes, which uses an Adapter and which works well.
And I know how to make a whole list expandable.
But, it it possible to have just a single item expandable, or does it have to be the whole list?? If so, how is it done?
A:
You would need to use Lists of one item each. Unfortunately there is no SDK widget that handles the special case you need.

You can insert (or remove) the 'child' items in the right place within your adapter's data set when the 'parent' is clicked using a normal ListView.

I don't think you can use a child view with an ArrayAdapter, or am I wrong?

Is it possible to have 2 ListViews, with one ListView 'stuck' to the bottom of the other, so they scroll together and look as if they are one?

@andy_spoo To create a 'child' view you could insert/remove an adapter item at position N+1 when the parent is clicked where position N is your parent. ArrayAdapter assumes a single item type and may not be appropriate for this depending on your data.To the second question: you could probably hack something together but the cleanest way to accomplish the effect would be to create a composite adapter that aggregates items from two or more adapters using a single ListView. Make sure item types are unique across the aggregated adapters.
