What you need to do is this:

1. Create a custom adapter for your GridView. In that adapter, provide a method for removing an item from the list of items it maintains, for example ‘void removeItem(int position)`

2. Call setOnItemLongClickListener to your grid. In this method, you get the position of the item that the long click occurred on. From this method, call the method to remove the item with the position you just received.

3. Notify the GridView that the data has changed using notifyDataSetchanged method. If you want the GridView UI to update immediately, you need to use Handler for this request to make sure it happens on the UI thread.
