首先，通过react native引入PanResponder

import {PanResponder} from 'react-native';
    
    
    　　//这里是当移动了超过20，才会进行隐藏或是显示
        _panResponder = PanResponder.create({

onStartShouldSetPanResponder: () => true,
            onMoveShouldSetPanResponder: () => true,
            onPanResponderGrant: () => {
                console.log('开始移动：');
                this.setState({ moveBG: '#eeeeee' })
            },
            onPanResponderMove: (evt, gs) => {
                console.log('正在移动：X轴：' + gs.dx + '，Y轴：' + gs.dy);
            },
            onPanResponderRelease: (evt, gs) => {
                console.log('结束移动：X轴：' + gs.dx + '，Y轴：' + gs.dy);
                this.setState({
                    moveBG: '#FFF'
                });
                if (gs.dy > 20) {
                    this.setState({
                        IsShowOrderInfoFlag: true
                    })
                } else if (gs.dy < -20) {
                    this.setState({
                        IsShowOrderInfoFlag: false
                    })
                }
            }
        });

以上为声明手势响应，将手势响应方法放入至某一个View中

Render方法中
    <View style={styles.container}>
                    {
                        this.state.IsShowOrderInfoFlag ?
                            <View style={[styles.headerView, { backgroundColor: '#e0e0e0' }]}>
                                <Text style={styles.orderInfoLabel}>{I18n.t('Component.HandmadeCheck.ComponentValue.Order.zdCode_Text')}{
        this.props.bundleEntity.bundleInfo.zdCode}</Text>
                                <Text style={styles.orderInfoLabel}>{I18n.t('Component.HandmadeCheck.ComponentValue.Order.Customer_Text')}{
        this.props.bundleEntity.bundleInfo.custName}|{
        this.props.bundleEntity.bundleInfo.custCode}</Text>
                                <Text style={styles.orderInfoLabel}>{I18n.t('Component.HandmadeCheck.ComponentValue.Bundle.Bundle_Text')}{
        this.props.bundleEntity.bundleInfo.bundle.groupNo}</Text>
                            </View>
                            :
                            null
                    }
                    <View style={[styles.headerView, { backgroundColor: this.state.moveBG }]} {...this._panResponder.panHandlers}>
                        <Text style={styles.headerLabel}>{I18n.t('Component.HandmadeCheck.ComponentValue.QAComment_Text')}</Text>
                        <TextInput style={styles.qaCommentText}

                                this.setState({ HandmadeCheckData: oldHandmadeCheckData })
                            }}
