有没有可能知道视图是否被包装 [英] is there any possibility to know if the View is wrapped

问题描述

我有一个 View 如下

<View style={{width: '60%', flexDirection: 'row', flexWrap: 'wrap'}}>
    { .....}
    { .....}
<View>

如果 View 中的项目能够在单行中呈现，否则 View 会相应地扩展到第二行.

if the items in the View are able to be rendered in the single line other wise View will be expanded to second line accordingly.

我的疑问是，有什么办法以编程方式知道 View 是否已包装?

Here my doubt is , Is there any way to know programatically that View is wrapped?

推荐答案

您可以创建对View的引用，并在其属性中检查其样式.在此处查看如何创建元素引用 https://reactjs.org/docs/refs-and-the-dom.html

You can create reference to View and check its styles in its properties. Check here for how to create element reference https://reactjs.org/docs/refs-and-the-dom.html
