使用react-native在post到服务器后清除文本框

import React, { useState } from 'react';
import { TextInput, Button, View } from 'react-native';

const App = () => {
  const [textValue, setTextValue] = useState('');

  const sendDataToServer = () => {
    // 发送数据到服务器的逻辑代码
    fetch('http://example.com/endpoint', {
      method: 'POST',
      body: JSON.stringify({ data: textValue }),
      headers: {
        'Content-Type': 'application/json',
      },
    })
      .then(response => response.json())
      .then(data => {
        // 发送成功后清空文本框内容
        setTextValue('');
      })
      .catch(error => {
        console.error('Error:', error);
      });
  };

  return (
    <View>
      <TextInput
        value={textValue}
        onChangeText={newValue => setTextValue(newValue)}
        placeholder="请输入内容"
      />
      <Button title="发送" onPress={sendDataToServer} />
    </View>
  );
};

export default App;
