如何解决类型“Readonly

Question

我有以下两段代码：

自定义标题。tsx

import { View, StyleSheet, Button } from 'react-native';
import { NavigationScreenProps } from 'react-navigation';
import Icon from 'react-native-vector-icons/Ionicons';


export  const CustomHeader = ({ navigation }: NavigationScreenProps) => (
    <View style={[styles.container]}>
      <Icon
        name="md-menu"
        size={32}
        color="black"
        style={{ marginLeft: 10 }}
        onPress={() => navigation.openDrawer()}
      />
    </View>
  );

  const styles = StyleSheet.create({
    container: {
      borderBottomWidth: 2,
      height: 70,
      paddingTop: 20,
    },
  });

详细信息屏幕。tsx

import React from 'react';
import { Text, View, Button, Alert } from 'react-native';
import { NavigationScreenProps } from "react-navigation";
import { CustomHeader } from '../components/Header';

export class ChangeAccountDetailScreen extends React.Component {
  render() {
    return (
      <View style={{ flex: 1 }}>
        <CustomHeader navigation={this.props.navigation} />
        <Text style={{ fontSize: 20 }}>Profile Screen</Text>
      </View>
    );
  }
}

在detailscreen中，我得到以下错误：

属性“导航”在“只读”类型上不存在

我搜索了这个问题，我知道它有一个问题，即我没有在CustomHeader中声明类型。然而，我不知道如何解决这个问题。我对打字有点陌生。有人能给我解释一下如何解决这类问题吗？

Answer 1

更现代的答案是使用useNaviation，如https://reactnavigation.org/docs/connecting-navigation-prop/中所述

import * as React from 'react';
import { Button } from 'react-native';
import { useNavigation } from '@react-navigation/native';

function GoToButton({ screenName }) {
  const navigation = useNavigation();

  return (
    <Button
      title={`Go to ${screenName}`}
      onPress={() => navigation.navigate(screenName)}
    />
  );
}

这是另一个解决方案，我在接口定义中添加了更多细节

js prettyprint-override">import React from 'react';
import { Text, View, Button, Alert } from 'react-native';
import {
  NavigationParams,
  NavigationScreenProp,
  NavigationState
} from 'react-navigation';
import { CustomHeader } from '../components/Header';

interface Props {
  navigation: NavigationScreenProp<NavigationState, NavigationParams>
}

export class ChangeAccountDetailScreen extends React.Component<Props> {
  render() {
    return (
      <View style={{ flex: 1 }}>
        <CustomHeader navigation={this.props.navigation} />
        <Text style={{ fontSize: 20 }}>Profile Screen</Text>
      </View>
    );
  }
}

我可能是错的，但您是否尝试过添加导航类型以达到预期

import React from 'react';
import { Text, View, Button, Alert } from 'react-native';
import { NavigationScreenProps } from "react-navigation";
import { CustomHeader } from '../components/Header';

interface Props {
  navigation: any
}

export class ChangeAccountDetailScreen extends React.Component<Props> {
  render() {
    return (
      <View style={{ flex: 1 }}>
        <CustomHeader navigation={this.props.navigation} />
        <Text style={{ fontSize: 20 }}>Profile Screen</Text>
      </View>
    );
  }
}
