react native 手势响应

官方翻译地址：https://reactnative.cn/docs/0.50/panresponder.html

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>

                        :
                        null
                }
