持续更新数组并在搜索过滤器栏中获取其值React Native应用程序？

import React, { useState } from 'react';

const App = () => {
  const [data, setData] = useState([]);

  // 更新数组的函数
  const updateArray = () => {
    // 更新数组的逻辑
    setData([...data, newValue]);
  };

  return (
    // 渲染界面的代码
  );
};

export default App;

import React, { useState } from 'react';

const App = () => {
  const [data, setData] = useState([]);
  const [filter, setFilter] = useState('');

  // 更新数组的函数
  const updateArray = () => {
    // 更新数组的逻辑
    setData([...data, newValue]);
  };

  // 更新搜索过滤器的函数
  const updateFilter = (value) => {
    setFilter(value);
  };

  return (
    <View>
      <TextInput
        value={filter}
        onChangeText={updateFilter}
        placeholder="Search"
      />
      // 渲染界面的代码
    </View>
  );
};

export default App;

import React, { useState } from 'react';

  // 更新数组的函数

    setData([...data, newValue]);
  };

  // 更新搜索过滤器的函数
  const updateFilter = (value) => {
    setFilter(value);
  };

  // 根据搜索过滤器的值对数组进行过滤
  const filteredData = data.filter((item) =>
    item.toLowerCase().includes(filter.toLowerCase())
  );

  return (
    <View>
      <TextInput

        onChangeText={updateFilter}
        placeholder="Search"
      />
      {filteredData.map((item, index) => (
        <Text key={index}>{item}</Text>
      ))}
    </View>
  );
