Thank you for your answer.
I think my explanations were confuse so your answer is not why I expected : it's my fault
Each cells contains :
- one letter which doesn't change
- or one number (values : 0 to 9)
- in the middle a time counter
- images wich have the same size (except the two big on a tablet).
The lines between cells are not visible.
I try to explain in an other way :
On a tablet, I want to adjust each cell (Label or Imageview) with relative width of 10% / 10% / 10% / 10% / 20% / 10% / 10% / 10% / 10% and relative height of 18% / 18% / 18% / 18% / 10%. And after that, I want that the size of a letter or number in a Label is adjusted at the maximum size (idem with Imageview). The goal is to have this grid covering all the surface of the screen and the size of text and images at the maximum depending of the size and resolution of the device
I have designed two layouts for tablet with large screen and small screen. I'm looking for something more "automatic".
Thanks
