You will not be able to increase number of items to 4. There always needs to be odd number of items on the screen, because we want to have one item in center. But you can increase number of items to 5, 7, ...

To do that you can ether pass xml parameter app:sideItems="2" or set it by code picker.setSideItems(2). This parameter will set number of items that are visible on each side of currently selected item. So if you would set it to 2 total of 5 items will be visible on screen.
