在react-native中通过TextInput的PanResponder

import React, { Component } from 'react';
import { TextInput, PanResponder } from 'react-native';

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

    this.panResponder = PanResponder.create({
      onStartShouldSetPanResponder: () => true,
      onPanResponderMove: this.handlePanResponderMove,
      onPanResponderRelease: this.handlePanResponderRelease,
    });
  }

  handlePanResponderMove = (e, gestureState) => {
    // 处理手势移动事件
    // 可以根据gestureState中的dx和dy来实现拖动效果
  }

  handlePanResponderRelease = (e, gestureState) => {
    // 处理手势释放事件
    // 可以根据gestureState中的dx和dy来实现拖动结束后的操作
  }

  render() {
    return (
      <TextInput
        {...this.props}
        {...this.panResponder.panHandlers}
      />
    );
  }
}

class App extends Component {
  render() {
    return (
      <MyTextInput
        style={{ width: 200, height: 40, borderWidth: 1 }}
      />
    );
  }
}
