擷取螢幕資訊：狀態列高度、content大小

public void getScreenInfo(final Activity activity){        final View v = activity.getWindow().findViewById(Window.ID_ANDROID_CONTENT);        v.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {            @Override            public boolean onPreDraw() {                Rect frame = new Rect();                activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);                int statusBarHeight = frame.top;                v.getViewTreeObserver().removeOnPreDrawListener(this);                Log.e("", "ScreenInfo===ContentVIew===Height:" + v.getHeight() + "  Width:" + v.getWidth() + " Top:" + v.getTop() + "  Left:" + v.getLeft()+"   Bottom:"+v.getBottom()+"   狀態列高度:"+statusBarHeight);                return true;            }        });    }

其他的一些工具類：擷取螢幕大小、密度、橫屏豎屏

private static int widthPixels = 0;    private static int heightPixels = 0;    private static float density = 0;    public static DisplayMetrics getMetrics(Context context) {        DisplayMetrics metrics = new DisplayMetrics();        getWindowManager(context).getDefaultDisplay().getMetrics(metrics);        return metrics;    }    public static String getOrientation(Context context) {        switch (getWindowManager(context).getDefaultDisplay().getRotation()) {            case Surface.ROTATION_0:                return "portrait";            case Surface.ROTATION_90:                return "landscape";            case Surface.ROTATION_180:                return "reverse portrait";            default:                return "reverse landscape";        }    }    public static WindowManager getWindowManager(Context context) {        return (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);    }    public static int getWidth(Context context) {        if (widthPixels == 0) {            widthPixels = getMetrics(context).widthPixels;        }        return widthPixels;    }    public static int getHeight(Context context) {        if (heightPixels == 0) {            ViewConfiguration.get(context).hasPermanentMenuKey();            heightPixels = getMetrics(context).heightPixels;        }        return heightPixels;    }    public static float getDensity(Context context) {        if (density == 0) {            density = getMetrics(context).density;        }        return density;    }
