react-native 身份证扫描（Android版）
IOS版本将在稍后补上
实现原理为Camera自动对焦成功后获取当前帧进行针对身份证的图像识别，识别后验证身份证，验证通过则返回，不通过则进行2次对焦并识别，直到通过为止
返回的字段包含【姓名】【身份证号】【性别】【年龄】
地址如需返回的，可修改源码的ScanView.class
npm install react-native-scanidcard在android目录下的settings.gradle中加入
include ':react-native-scanidcard' project(':react-native-scanidcard').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-scanidcard/android/app') include ':idcard-library' project(':idcard-library').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-scanidcard/android/idcard-library')在android/app中的build.gradle中加入
compile project(':react-native-scanidcard') compile project(':idcard-library')在android/app/src MainApplication中加入
import com.scanidcard.ScanPackage; 在android/app/src MainApplication的getPackages方法中加入
new ScanPackage() import React, { Component } from 'react'; import { AppRegistry, StyleSheet, Text, Vibration, View, TextInput, DeviceEventEmitter } from 'react-native'; import ScanView from 'react-native-scanidcard'; class ScanScreen extends Component { constructor(props) { super(props); this.state = { torchMode: 'off', cameraType: 'back' }; } componentDidMount() { this.listener = DeviceEventEmitter.addListener('scanCallBack', this.scanCallBack.bind(this)); //对应了原生端的名字 } componentWillUnmount() { this.listener && this.listener.remove(); //记得remove哦 this.listener = null; } scanCallBack(e) { console.info(e) } render() { return ( <ScanView style={{ flex: 1 }} torchMode={this.state.torchMode} cameraType={this.state.cameraType} /> ); } } export default ScanScreen;感谢dreamkid提供的library
