如何使用 Unity UI 滚动到 ScrollRect 中的特定元素? [英] How to scroll to a specific element in ScrollRect with Unity UI?

问题描述

我使用 Unity 5.1 为手机游戏构建了一个注册表单.为此，我使用 Unity UI 组件:ScrollRect + Autolayout(垂直布局)+ Text(标签)+ Input Field.这部分工作正常.

I built a registration form for a mobile game using Unity 5.1. To do that, I use Unity UI components: ScrollRect + Autolayout (Vertical layout) + Text (labels) + Input Field. This part works fine.

但是，当键盘打开时，选定的字段在键盘下.有没有办法以编程方式滚动表单以显示所选字段?

But, when keyboard is opened, the selected field is under keyboard. Is there a way to programmatically scroll the form to bring the selected field into view?

我尝试使用 ScrollRect.verticalNormalizedPosition 并且可以很好地滚动一些，但是我无法让选定的字段出现在我想要的位置.

I have tried using ScrollRect.verticalNormalizedPosition and it works fine to scroll some, however I am not able to make selected field appear where I want.

        contentPanel.anchoredPosition =
            (Vector2)scrollRect.transform.InverseTransformPoint(contentPanel.position)
            - (Vector2)scrollRect.transform.InverseTransformPoint(target.position);
    }
