public static Point getDisplaySize(Context context) {    WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);    Display display = wm.getDefaultDisplay();    Point size = new Point();    display.getSize(size);    return size;}Point size = getDisplaySize(this);int width = size.x; int height = size.y;

2、获取屏幕宽/高(二)

 DisplayMetrics metric = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metric); int mScreenWidth = metric.widthPixels; int mScreenHeight = metric.heightPixels; float mDensity = metric.density;
