React Native使用Modal自定义分享界面的示例代码

React Native使用Modal自定义分享界面的示例代码

在很多App中都会涉及到分享，React Native提供了Modal组件用来实现一些模态弹窗，例如加载进度框，分享弹框等。使用Modal搭建分析的效果如下：

自定义的分析界面代码如下：

ShareAlertDialog.js

/**

* https://github.com/facebook/react-native

* @flow 分享弹窗

*/

import React, {Component} from 'react';

import {View, TouchableOpacity, Alert,StyleSheet, Dimensions, Modal, Text, Image} from 'react-native';

import Separator from "./Separator";

const {width, height}nnQKqKskJb = Dimensions.get('window');

const dialogH = 110;

export default class ShareAlertDialog extends Component {

constructor(props) {

super(props);

this.state = {

isVisible: this.props.show,

};

}

componentWillReceiveProps(nextProps) {

this.setState({isVisible: nextProps.show});

}

closeModal() {

this.setState({

isVisible: false

});

this.props.closeModal(false);

}

renderDialog() {

return (

选择分享方式

Alert.alert('分享到微信朋友圈')}>

source={require('../images/share_ic_friends.png')}/>

微信朋友圈

nnQKqKskJb source={require('../images/share_ic_weixin.png')}/>

微信好友

source={require('../images/share_ic_weibo.png')}/>

新浪微博

)

}

render() {

return (

transparent={true}

visible={this.state.isVisible}

animationType={'fade'}

onRequestClose={() => this.closeModal()}>

onPress={() => this.closeModal()}>

{this.renderDialog()}

);

}

}

const styles = StyleSheet.create({

container: {

flex: 1,

backgroundColor: 'rgba(0, 0, 0, 0.5)',

},

modalStyle: {

position: "absolute",

top: height - 170,

left: 0,

width: width,

height: dialogH,

backgroundColor: '#ffffff'

},

subView: {

width: width,

height: dialogH,

backgroundColor: '#ffffff'

},

text: {

flex: 1,

fontSize: 18,

margin: 10,

justifyContent: 'center',

alignItems: 'center',

alignSelf: 'center'

},

item: {

width: width / 3,

height: 100,

alignItems: 'center',

backgroundColor: '#ffffff'

},

image: {

width: 60,

height: 60,

marginBottom: 8

},

});

当点击某个按钮之后，就会弹出框，示例代码如下：

constructor(props) {

super(props);

this.state = {

showSharePop: false,//分享弹窗，默认不显示

}

}

//省略

onSharePress() {

this.setState({showSharePop: !this.state.showSharePop})

}

//增加点击

navigator={this.props.navigator}

popEnabled={false}

style={{backgroundColor: "transparent", position: "absolute", top: 0, width}}

leftButton={ViewUtils.getLeftButton(() => this.props.navigator.pop())}

rightButton={ViewUtils.getShareButton(() => this.onSharePress())}/>

//添加ShareAlertDialog自定义组件

{

this.setState({showSharePop: show})

}} {...this.props}/>

source={require('../images/share_ic_friends.png')}/>

微信朋友圈

nnQKqKskJb source={require('../images/share_ic_weixin.png')}/>

微信好友

source={require('../images/share_ic_weibo.png')}/>

新浪微博

)

}

render() {

return (

transparent={true}

animationType={'fade'}

onRequestClose={() => this.closeModal()}>

onPress={() => this.closeModal()}>

{this.renderDialog()}

);

}

}

const styles = StyleSheet.create({

modalStyle: {
