在 React Native 的标签中传递道具 [英] pass props in tabs in react native

问题描述

我想知道如何将状态从我的主页传递到选项卡?目前我正在使用导航将道具从一个页面转移到另一个页面，但从选项卡看来我不能这样做，你有关于如何将道具传递给选项卡的函数或示例代码吗?

I would like to know how to pass a state from my main page to the Tabs? Currently I'm using navigate to transfer props from one page to another page but from Tabs it seems I cannot do that, do you have a function or sample code on how to pass props to the Tabs?

推荐答案

像这样简单地将 state 作为 props 传递:

Simply Pass the state as props like this:

<SampleComponent 
   sampleProps={this.state.MyMainPageState} 
/>

从那里你可以在你的 SampleComponent 作为道具访问它;)

from there you can access it at your SampleComponent as props ;)

在 SampleComponent 中，您可以尝试记录它:

inside SampleComponent you can try logging it:

//this is the state from your mainPage
const {sampleProps} = this.props; 
 console.log(sampleProps); 

应该这样做
