Answer 1

im not really sure if this is what you are looking for.. but you can check the screen size of the phone

 Display display = getWindowManager().getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        int width = size.x;
        int height = size.y;

and set it

if(width == 480 || height == 800){
            //get resource here
 } else if (width < 480 || height < 800) {
       //get resource here

this is just an example hope it helps.

Your problem tells me that you are using layouts incorrectly. The layout needs to be able to fit itself inside an approximate screen size. That is what the "normal", "large", etc. screen size buckets are for. Your layout should not take up exactly "5.1" inches, because there are so many different screen sizes, that you would have to make an overwhelming number of layouts if you took this approach.

You simply need to use RelativeLayout or LinearLayout with layout_weight on the contents, and you will be able to use the same layout with multiple slightly different screen sizes.
