If datashop is the data structure your FavShopAdapter is using, you don't have to re-instatiate a new FavShopAdapter each time. Just remove the item from the list, and instead of adapter = new FavShopAdapter(data_shop,getApplicationContext()); listview.setAdapter(adapter);} you can call adapter.notifyDataSetChanged(); which will update the list for you.
