Height of screen without status bar, actionBar and tabs

You can use this code:

public int getStatusBarHeight() { 
      int result = 0;
      int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
      if (resourceId > 0) {
          result = getResources().getDimensionPixelSize(resourceId);
      } 
      return result;
}

Please try using this solution and tell us if it worked. ;)

Based on @rasmeta 's answer I made this code and it does the trick. My rows are now exactly a third of the available screen. Here is how to get the height of the status bar:

int resource = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resource > 0) {
        statusBarHeight = context.getResources().getDimensionPixelSize(resource);
    }

And the calculation of the height of each row goes like this:

holder.imageView.getLayoutParams().height = (screenHeight - statusBarHeight - actionBarHeight*2) / 3;
// actionBarHeight * 2 because the tabs have the same height as the actionBar.
