推荐答案

是layoutlistener有创建您的滚动视图时，所有的方式滚动视图以正确的？如果是这样你应该然后删除您onGlobalLayout函数中的事件侦听器，否则一旦进入奠定了它会向右滚动。

is your layoutlistener there to scroll your view all the way to the right when your scrollview is created? If so you should then remove the event listener inside your onGlobalLayout function, otherwise it will scroll right whenever it gets laid out.
