如何在react native中更改listview中按钮的文本？

import React, { Component } from 'react';
import { View, Text, ListView, TouchableOpacity } from 'react-native';

class MyComponent extends Component {
  constructor(props) {
    super(props);

    // 初始化数据源
    const dataSource = new ListView.DataSource({ rowHasChanged: (r1, r2) => r1 !== r2 });
    this.state = {
      data: dataSource.cloneWithRows([
        { id: 1, text: 'Button 1' },
        { id: 2, text: 'Button 2' },
        { id: 3, text: 'Button 3' },
      ]),
    };
  }

  handleButtonPress(rowData) {
    // 根据按钮的文本值来修改数据源中对应项的文本
    const newData = this.state.data._dataBlob.s1.map((item) => {
      if (item.id === rowData.id) {
        return { ...item, text: 'New Text' };
      }
      return item;
    });

    // 更新state中的数据源
    this.setState({
      data: this.state.data.cloneWithRows(newData),
    });
  }

  renderRow(rowData) {
    return (
      <View>
        <TouchableOpacity onPress={() => this.handleButtonPress(rowData)}>
          <Text>{rowData.text}</Text>
        </TouchableOpacity>
      </View>
    );
  }

  render() {
    return (
      <ListView
        dataSource={this.state.data}
        renderRow={this.renderRow.bind(this)}
      />
    );
  }
}

export default MyComponent;
