Remarks
A structure describing general information about a display, such as its size, density, and font scaling.
To access the DisplayMetrics members, retrieve display metrics like this:
context.getResources().getDisplayMetrics();
For UI layout, obtain android.view.WindowMetrics from WindowManager#getCurrentWindowMetrics(). DisplayMetrics should only be used for obtaining display related properties, such as #xdpi and #ydpi
See #density for more information about the differences between #xdpi, #ydpi and #density.
