navigation.setOptions不改变

Posted 2021-03-19

我在用react-navigator创建屏幕，但当屏幕打开时，我不能改变标题栏的选项。

我的代码（App.js）。

function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator screenOptions={{
        headerTitleAlign: 'center',
        headerTitle: props => <LogoTitle {...props} />,
        headerRight: props => <HeaderRight {...props} />,
        headerStyle: {
          backgroundColor: '#F46A0D'
        },
        headerTintColor: '#fff',
      }}>
        <Stack.Screen name="Search" component={SearchScreen}/>
      </Stack.Navigator>
    </NavigationContainer>
  );
}

export default App;

我的SearchScreen. js:

import React from 'react'
import { Text, View } from 'react-native'
import { Button } from 'react-native-paper'

const SearchScreen = ({ navigation }) => {
    navigation.setOptions = {
        headerTitle: props => <TextInput {...props} placeholder="Search" placeholderTextColor="#FFFF" style={{
            fontSize: 24
        }}></TextInput>,
        headerRight: props => <FontAwesome5 {...props} name={'search'} size={22} color="white" style={{ marginRight: 15 }}></FontAwesome5>
    }
    return (
        <View>
        </View>
    )
}

export default SearchScreen;

在navigation.setOptions一行什么都没有发生，默认的screenOptions Stack.Navigator继续运行。

答案

试着改变这个

    navigation.setOptions = {
        headerTitle: props => <TextInput {...props} placeholder="Search" placeholderTextColor="#FFFF" style={{
            fontSize: 24
        }}></TextInput>,
        headerRight: props => <FontAwesome5 {...props} name={'search'} size={22} color="white" style={{ marginRight: 15 }}></FontAwesome5>
    }

对此。

    navigation.setOptions({
      headerTitle: props => <TextInput {...props} placeholder="Search" placeholderTextColor="#FFFF" style={{
          fontSize: 24
      }} />,
      headerRight: props => <FontAwesome5 {...props} name={'search'} size={22} color="white" style={{ marginRight: 15 }}></FontAwesome5>
    })
