refresh listview created from an arraylist after delete operation

Question

I have seen too many questions about refreshin a listview and I have tried every solution on the topics but none worked for me.

have tried notifysetdatachange(), invalidateviews, refreshdrawablestate() but none worked.

I have an arraylist and after an longclick operation I am deleting an item from arraylist.and I want it to disappear from listview.but it does not.

but after deletion if I open another activity and turn back to the activity which contains my listview it disappears.

so my deletion operation is successful, I just want to know how to refresh listview.,

I did not post a code because there is nothing unique I am just using

I have an arraylist named al_6.I am filling it with objects.

then I send them to the my adapter like

adapter = new ContentSearchListAdapter(getActivity(), channels2,
                options);
        listview.setAdapter(adapter);

and when I want to delete an object from my arraylist.

al_6.remove(position)

and as I said before the deletion operation is successful

Answer 1

Your should use these syntax for achieving it

((YourAdaptor)Listview.getAdaptor()).notifyDataSetChange();
