Android 获得手机屏幕真实的宽高

http://stackoverflow.com/questions/1016896/get-screen-dimensions-in-pixels

WindowManager w = activity.getWindowManager();Display d = w.getDefaultDisplay();DisplayMetrics metrics = new DisplayMetrics();d.getMetrics(metrics);// since SDK_INT = 1;widthPixels = metrics.widthPixels;heightPixels = metrics.heightPixels;try {    // used when 17 > SDK_INT >= 14; includes window decorations (statusbar bar/menu bar)    widthPixels = (Integer) Display.class.getMethod("getRawWidth").invoke(d);    heightPixels = (Integer) Display.class.getMethod("getRawHeight").invoke(d);} catch (Exception ignored) {}try {    // used when SDK_INT >= 17; includes window decorations (statusbar bar/menu bar)    Point realSize = new Point();    Display.class.getMethod("getRealSize", Point.class).invoke(d, realSize);    widthPixels = realSize.x;    heightPixels = realSize.y;} catch (Exception ignored) {}

EDIT: slightly improved version (avoid firing exceptions on non-supported OS version):

WindowManager w = activity.getWindowManager();Display d = w.getDefaultDisplay();DisplayMetrics metrics = new DisplayMetrics();d.getMetrics(metrics);// since SDK_INT = 1;widthPixels = metrics.widthPixels;heightPixels = metrics.heightPixels;// includes window decorations (statusbar bar/menu bar)if (Build.VERSION.SDK_INT >= 14 && Build.VERSION.SDK_INT < 17)try {    widthPixels = (Integer) Display.class.getMethod("getRawWidth").invoke(d);    heightPixels = (Integer) Display.class.getMethod("getRawHeight").invoke(d);} catch (Exception ignored) {}// includes window decorations (statusbar bar/menu bar)if (Build.VERSION.SDK_INT >= 17)try {    Point realSize = new Point();    Display.class.getMethod("getRealSize", Point.class).invoke(d, realSize);    widthPixels = realSize.x;    heightPixels = realSize.y;} catch (Exception ignored) {}
