navigation.setOptions 不改变

Question

我正在使用反应导航器创建屏幕，但当屏幕打开时我无法更改标题栏的选项

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 行中没有任何反应，默认 screenOptions Stack.Navigator 继续

Answer 1

在路线文件上

<Stack.Screen
    name="FuncName"
    component={FuncName}
    options={{
    headerTitle:''
}}/>

按下后转到 FuncName 屏幕

onPress={()=>{
    props.navigation.navigate("FuncName",{title:"title"})
  }}

然后通过道具标题更改标题

const FuncName = (props) => {
useEffect(()=>{
      props.navigation.setOptions({ headerTitle: props.route.params.title  })
  },[])
}

Answer 2

尝试改变这个

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>
})
