Listview Does Not Refresh Dynamically And Causes Error

I am unable to remove an object in a ListView. I have been trying to remove an object from an adapter, and then call onDataSetChanged(); but it does not seem to ever remove the obj

Solution 1:

The problem was solved by removing the following lines of code in the swipeDismissViewListener and the OnActivityResult.

DatabaseHandler db = new DatabaseHandler(context); EventAdapter adapter = new EventAdapter(context, db.getAllContacts());
