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
import React, {Component} from 'react';
import {View, TouchableOpacity, alert,StyleSheet, Dimensions, Modal, Text, Image} from 'react-native';
import Separator from "./Separator";
const {width, height} = 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')}>
微信朋友圈
微信好友
新浪微博
)
}
render() {
return (
this.closeModal()}>
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
this.props.navigator.pop())}
rightButton={ViewUtils.getShareButton(() => this.onSharePress())}/>
//添加SharealertDialog自定义组件
{
this.setState({showSharePop: show})
}} {...this.props}/>
