如何在两个react-native-swiper组件之间进行拖动? [英] How to enable dragging between two react-native-swiper components?
问题描述
我正在尝试在两个react-native-swiper组件之间启用拖放。
我使用Animated.Text和PanResponder在底部一个react-native-swiper中拖动文本,并且它的工作方式正确,直到将拖动移到上方一个react-native-swiper组件上为止。
I am trying to enable drag-and-drop between two react-native-swiper components. I used Animated.Text and PanResponder to drag the text in bottom one react-native-swiper and it is working corretly until when the dragging is moved over the above one react-native-swiper componenent. The dragged text is unvisible when dragging over the other react-native-swiper.
有人可以解释正在发生的事情以及如何解决该行为吗?
Could anyone explain what is happening and how to fix the behaviour?
以下是重现行为的简化代码:
Here is the simplefied code to reproduce the behaviour:
import React from 'react';
import {
StyleSheet,
Text,
View,
PanResponder,
Animated,
Dimensions } from 'react-native';
import Swiper from 'react-native-swiper';
const SCREEN_WIDTH = Dimensions.get('window').width;
export default class App extends React.Component {
constructor(props) {
super(props);
const position = new Animated.ValueXY();
const panResponder = PanResponder.create({
onStartShouldSetPanResponder: () => true,
onPanResponderMove: (event, gesture) => {
position.setValue({ x: gesture.dx, y: gesture.dy });
},
onPanResponderRelease: () => {}
});
this.state = { panResponder, position };
}
renderAnimatedText(text) {
return (
<Animated.Text
style={[this.state.position.getLayout(), styles.text]}
{...this.state.panResponder.panHandlers}
>
{text}
</Animated.Text>
);
}
render() {
return (
<View style={styles.container}>
<View style={styles.swiperContainer}>
<Swiper style={styles.wrapper}>
<View style={styles.slide3}>
<Text style={styles.text}>Hello Stephen</Text>
</View>
<View style={styles.slide2}>
<Text style={styles.text}>Hello Helpers</Text>
</View>
<View style={styles.slide1}>
<Text style={styles.text}>Hello World</Text>
</View>
</Swiper>
</View>
<View style={styles.swiperContainer}>
<Swiper style={styles.wrapper}>
<View style={styles.slide1}>
{this.renderAnimatedText('You are The Best')}
</View>
<View style={styles.slide2}>
<Text style={styles.text}>and Greatest</Text>
</View>
<View style={styles.slide3}>
<Text style={styles.text}>Thank you</Text>
</View>
</Swiper>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
swiperContainer: {
height: 250,
width: SCREEN_WIDTH
},
wrapper: {
},
slide1: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#9DD6EB',
},
slide2: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#97CAE5',
},
slide3: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#92BBD9',
},
text: {
color: '#ff0',
fontSize: 30,
fontWeight: 'bold',
}
});

推荐答案
我设法通过设置对刷卡器可见的溢出来解决该问题:
I managed to solve the issue by setting overflow visible for the swiper:
<Swiper style={{ overflow: 'visible' }}>
但不幸的是,这仅适用于iOS。在Android上,这似乎是一个相当大的问题:

But unfortunately this works only on iOS. It seems to be quite major issue on Android: https://github.com/facebook/react-native/issues/6802
任何解决方法或更新使其在Android上都能正常使用。
Any workaround or update to get this to work on Android would be really appreciated.
