React native React本机Flatlist单选渲染错误只读

您好，我正在尝试创建一个单选平面列表。用户将从这里选择游戏联盟中的他/她，但我有一个错误。selectedID是只读的。我希望他们选择联盟，并将有一个保存按钮。我看不到我缺少的内容。我研究了它，但找不到任何帮助

import React , {useState} from 'react';
import {
  StyleSheet,
  Text,
  View,
  SectionList,
  SafeAreaView,
  Image,
  FlatList,
  StatusBar,
  TouchableOpacity
} from 'react-native';



export default () => {
  const [selectedID,setSelectedID] = useState(0);

  const ListItem = ({ item }) => {
    return (
      <TouchableOpacity onPress = {() => setSelectedID(item.id)}>
      <View style={[styles.item , selectedID = item.id ?
      styles.itemSelected:styles.itemUnselected]}>
        
        <Image
          source={{
            uri: item.uri,
          }}
          style={styles.itemPhoto}
          resizeMode="cover"
        />
        
        <Text style={styles.itemText}>{item.text}</Text>
      </View>
      </TouchableOpacity>
    );
  };

  return (
    <View style={styles.container}>
      <StatusBar style="light" />
      <SafeAreaView style={{ flex: 1 }}>
        <SectionList
          contentContainerStyle={{ paddingHorizontal: 10 }}

          renderSectionHeader={({ section }) => (
            <>

              {section.horizontal ? (
                <FlatList
                  horizontal
                  data={section.data}
                  renderItem={({ item }) => <ListItem item={item} />}
                  showsHorizontalScrollIndicator={false}
                />
              ) : null}
            </>
          )}
          renderItem={({ item, section }) => {
            if (section.horizontal) {
              return null;
            }
            return <ListItem item={item} />;
          }}
        />

您正在将值分配给状态变量

我该怎么办我是react native的新手您能更具体一些吗请从样式中删除状态变量赋值，而使用类似fontWeight:variableToCompare的语法？粗体：正常
