Question

I have a layout with an imageview. This imageview should have a 4/3 ratio. In portrait mode i get the width of the screen then compute the height and set the imageView dimensions.

int[] tailles       = new int[2];
DisplayMetrics dm   = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int widthScreen     = dm.widthPixels;
tailles[0]          = widthScreen;
tailles[1]          = (tailles[0]*3)/4;

This part works great.

In landscape mode i need to set the imageView width according to the available height. So i need to get the height of the screen minus the status/notification bar.

I saw the value of 48px for the bar in this question. Is it a standard size ?

What the best solution to get the available height regardless of the used device ?

If you’re creating an Activity, than you have to have some sort of layout. Get it’s root component, and retrieve it’s size (getWidth, getHeight). That’ll be the available width and height without counting the status bar.
