Believe that when you see this article, most people have seen a lot of things to get screen pixels, from other articles we know that the pixel of the screen is based on the Displaymetrics class to get
The concrete calculation method is width = widthpixels * density; Height = heightpixels * Density (ps:widthpixels and heightpixels, density are all obtained from displaymetrics).
Copy Code code as follows:
Displaymetrics dm = new Displaymetrics ();
Getwindowmanager (). Getdefaultdisplay (). Getmetrics (DM);
int widthpixels= dm.widthpixels;
int heightpixels= dm.heightpixels;
float density = dm.density;
int screenwidth = widthpixels * density;
int screenheight = heightpixels * density;
The Widthpixels value on 320*480 's phone is heightpixels, and the density value is 1.0.
The Idthpixels value on 480*800 's phone is heightpixels, and the density value is 1.5.
Note: displaymetrics do not use Context.getapplicationcontext (). Getresources (). Getdisplaymetrics ();
The density value I got when I tested this method in Nexus One was 1.0, so that I didn't get the right 480 * 800 pixels.
