1、获取状态栏高度

private int getStatusBarHeight() {        Rect rectangle = new Rect();        Window window = getWindow();        window.getDecorView().getWindowVisibleDisplayFrame(rectangle);        int statusBarHeight = rectangle.top;        if (statusBarHeight == 0) {            int resourceId = getResources().getIdentifier(                    "status_bar_height", "dimen", "android");            if (resourceId > 0) {                statusBarHeight = getResources()                        .getDimensionPixelSize(resourceId);            }        }        return statusBarHeight;    }
