本文實例講述了Android編程實現獲得手機屏幕真實寬高的方法。分享給大家供大家參考，具體如下：
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) {}補:改進版 (彌補了原先非支持版本的一些異常):
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) {}希望本文所述對大家Android程序設計有所幫助。
