Does anyone know how to programatically add buttons to the layout from an array? I have an array of titles and icons that i have used for a list view and now i'm wanting to reuse the same arrays to create a layout as displayed here

so the layout adds a button for each item in the array and arranges them in 3's according to device width. is this possible to do? I have tried using a custom Array Adapter to generate the Grid but getting a null pointer error at the point

    menuGrid = (GridView) findViewById(R.id.gridView1);

      MenuItemsSetup menuData[] = new MenuItemsSetup[]
            {
                new MenuItemsSetup(R.drawable.ic_menu_icon1, "menuItem1"),
                new MenuItemsSetup(R.drawable.ic_menu_icon2, "menuItem2"),
                new MenuItemsSetup(R.drawable.ic_menu_icon3, "menuItem3"),
                new MenuItemsSetup(R.drawable.ic_menu_icon4, "menuItem4"),
                new MenuItemsSetup(R.drawable.ic_menu_icon5, "menuItem5"),
                new MenuItemsSetup(R.drawable.ic_menu_icon6, "menuItem6"),
                new MenuItemsSetup(R.drawable.ic_menu_icon7, "menuItem7"),
                new MenuItemsSetup(R.drawable.ic_menu_icon8, "menuItem8")
            };


   String[] menuBgColours = {"#FFFFFF","#FFFFFF",                           ,"#888888", "#FFFFBB", "#BBFFFF","#000000", "#666666"};

            CustomArrayAdapter adapter = new CustomArrayAdapter(this, 
                    R.layout.drawer_list_item, menuData, menuBgColours);


            menuList.setAdapter(adapter);
           menuGrid.setAdapter(adapter);
