我可以在react-native调用导航器分派方法时传递状态吗? [英] Can I pass state at the time of navigator dispatch method calling in react-native?

问题描述

我想在调度动作调用时在抽屉式菜单/导航器上传递一个状态.

I want to pass a state on drawer menu/navigator at the time of dispatch action calling.

<Button
title='Filter'
onPress={() => navigation.dispatch(DrawerActions.openDrawer())}
/>

推荐答案

您应该调用调度函数，并使用this.props.navigation.setParams设置何时安装组件.

You should call your dispatch function and set when your component is mounted using this.props.navigation.setParams

在组件中设置调度功能

this.props.navigation.setParams({
   dispatch: this.dispatch.bind(this)
})

dispatch(){
 //your code
}
