        public int getSpanSize(int position) {
            if (position == 0)
                return 5;

            else
                return 2;

        }
    });

Answer 1

You don't mention how many total spans you have across but I guess that it is 5.

The number of spans you define should be even divisible by the size of each item. So, divisible by 1 (of course), 5 and 2. 1*5*2=10, 10 spans will do. Create your GridLayoutManager with 10 spans.

Now, when you want just one item in a row, return 10 from setSpanSizeLookup(). If you want 2 items, then return 5. For 5 items return 2.

Your code will look something like this:

mLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
    @Override
    public int getSpanSize(int position) {
        if (position == 0)
            return 10;
        else if (position < 6)
            return 2;
        else
            return 5;

    }
});
