Question

I have asked this before however I am still having issues with this problem!

Basically, I am hardcoding pixel values when using a canvas to draw images for a game.

How would I go about the process of making this game suitable for any screen size as obviously the pixel values for one screen wont run properly on a different screen!

Thanks in advance

Answer 1

Why do you need pixel values? Use dp not px values!!

final float scale = getContext().getResources().getDisplayMetrics().density;
int px = (int) (dp * scale + 0.5f);

dp Density-independent Pixels – an abstract unit that is based on the
physical density of the screen. These units are relative to a 160 dpi
(dots per inch) screen, so 160dp is always one inch regardless of the
screen density. The ratio of dp-to-pixel will change with the screen
density, but not necessarily in direct proportion. You should use
these units when specifying view dimensions in your layout, so the UI
properly scales to render at the same actual size on different
screens. (The compiler accepts both “dip” and “dp”, though “dp” is
more consistent with “sp”.)
