    public static int getStatusBarHeight(Context context)
    {
        int result = 0;
        int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0)
        {
            result = context.getResources().getDimensionPixelSize(resourceId);
        }
        return result;
    }
}

用法:

Activiy onCreate中添加：

StatusBarCompat.compat(this);

如果需要制定状态栏颜色,使用此方法：

StatusBarCompat.compat(this, 0xFFFF0000);
