Android Refresh Adapter With Baseadapter

in this code after insterting new items to adapert my list could not refresh and update with notifyDataSetChanged() for example for this line my adapter could set without any probl

Solution 1:

Instead of creating a new items each time and setting it to adapter.. try to add and remove from the adapter directly.

First initialize the adapter with initial values you need or an empty list.

1. Next when you want to add.. call adapter.add(obj)
2. When you want to remove call adapter.remove(obj)
3. When you want to empty the adapter call adapter.clear()

Finally call the adapter.notifyDatasetChanged() whenever you need the changes to be reflected

Solution 2:

Try this way,hope this will help you to solve your problem.
