Answer 1

Your model classes of your gridItems for your adapter should have an attribute 'color' .

In your getView method - when the 'position' is 3,7,11...etc change the gridview layout color and use the setColor attribute of your item to set the color to that particular item.

Along with this at the start of your getView method you can check if item.getColor is set then change the gridview layout color else it should have the default color.

For getting the desired position you can use the formula if position = (4n-1) which will give you your desired color changing positions ie 3,7,11....
