For an ArrayAdapter , notifyDataSetChanged only works if you use the add , insert , remove , and clear on the Adapter. When an ArrayAdapter is constructed, it holds the reference for the List that was passed in. If you were to pass in a List that was a member of an Activity, and change that Activity member later, the ArrayAdapter is still holding a reference to the original List. The Adapter does not know you changed the List in the Activity. Your choices are: Use the functions of the ArrayAdapter to modify the underlying List add , insert , remove , clear , etc. Re-create the ArrayAdapter with the new List data.
