Android : Android - Creating a dynamic GridLayout with addView

How can I make my GridLayout dynamic (Adapting to different size views when I do layout.addView(newView, lp)) when I click a button, that button adds a view. But the view's size is chosen by the user. I just need to know how to dynamically add views of different sizes without having to set the layoutparams for each one.

My GridLayout is currently set out like this:

╔===============╗ ╔=======╗
║               ║ ║       ║
║               ║ ║   2   ║
║               ║ ║       ║
║               ║ ╚=======╝
║               ║ ╔=======╗
║       1       ║ ║       ║
║               ║ ║       ║
║               ║ ║   3   ║
║               ║ ║       ║
║               ║ ║       ║
║               ║ ║       ║
╚===============╝ ╚=======╝
╔=========================╗
║                         ║
║            4            ║
║                         ║
╚=========================╝

And add more views like this in order (1,2,3,4).

Any help is appreciated.

Thanks
