The DisplayMetrics constructor does not need to pass any parameters. After getWindowManager () is called, Handle of the existing Activity is obtained. At this time, the getdefadisplay display () method stores the obtained width and height dimensions in the DisplayMetrics object, the obtained width and height dimensions are measured in pixels. "pixels" refer to "absolute pixels" rather than "relative pixels ".
