How can remove adapter from Listview, Android

I use SimpleAdapter with custom row layout for Listview

SimpleAdapter adapter = new SimpleAdapter(ListOrder.this, oslist,
                    R.layout.list_v, 
                    new String[] { "name","time","status" }, 
                    new int[] { R.id.tablename, R.id.timeorder, R.id.status});
            list.setAdapter(adapter);

After , i reload data of Listview and i want remove old data. I don't know how i can't remove old data before add new data to Listview.

I used 

adapter.remove(adapter.getItem(i));

but have error

The method remove(Object) is undefined for the type SimpleAdapter

Please help me ! Thank you!

Solution

  • Just modify the underlying List and inform the adapter about it. Like that:

    oslist.clear();
adapter.notifyDataSetChanged();

    if you only want to remove one or two:

    oslist.remove(index);
adapter.notifyDataSetChanged();
