安卓识别身份证，自动提取身份证信息功能实现（附源码）

源码下载地址：注：源码里没有腾讯优图的账号需要填写自己的下载地址

先讲几下.首先我们需要去腾讯优图申请一个账号，因为身份证识别需要用到第三方接口如图所示

我申请的是扫描身份证，当然还有其他的功能，比如扫描银行卡，营业执照，车牌等等，大家可以去研究一下

1.记得配权限，需要读写SD卡 ,还需要网络的权限记得引入第三方库，本人很懒，反正能少些代码的，绝对不手打，能用第三库解决的，绝不自己动手，哈哈

    //网络请求库compile 'org.xutils:xutils:3.3.36'//图片选择器库compile 'com.github.LuckSiege.PictureSelector:picture_library:v2.2.3'//解析库compile 'com.google.code.gson:gson:2.7'

还有,记得在allprojects添加下代码

allprojects {repositories {maven { url 'https://jitpack.io' }maven { url 'https://maven.google.com' }//图片选择器库maven {url "http://dl.bintray.com/nuptboyzhb/maven"}google()jcenter()}
}

下面配置好权限

    <!-- 读写 --><uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" /><!-- 用于申请调用照相机 --><uses-permission android:name="android.permission.CAMERA" />

然后新建一个Application配置下网络请求吧

public class MyApplication extends Application {@Overridepublic void onCreate() {super.onCreate();
//网络请求x.Ext.init(this);}
}

记得在Manifests中设置一下name=.MyApplication

 <applicationandroid:name=".MyApplication"android:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:roundIcon="@mipmap/ic_launcher_round"android:supportsRtl="true"android:theme="@style/AppTheme">

接下来是布局文件来，等会上代码了

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@color/white"android:orientation="vertical"><ScrollViewandroid:layout_width="match_parent"android:layout_height="match_parent"android:fillViewport="true"android:scrollbars="vertical"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="vertical"><ImageViewandroid:id="@+id/activity_autonym_certification_iv_positive"android:layout_width="match_parent"android:layout_height="180dp"android:layout_marginRight="30dp"android:layout_marginLeft="30dp"android:layout_marginTop="20dp"android:background="@drawable/autonym_certification_iv_line"android:padding="20dp"android:src="@mipmap/idcard_positive" /><ImageViewandroid:id="@+id/activity_autonym_certification_iv_reverse"android:layout_width="match_parent"android:layout_height="180dp"android:layout_marginTop="25dp"android:layout_marginRight="30dp"android:layout_marginLeft="30dp"android:background="@drawable/autonym_certification_iv_line"android:padding="20dp"android:src="@mipmap/idcard_reverse" /><LinearLayoutandroid:layout_marginRight="30dp"android:layout_marginLeft="30dp"android:layout_marginTop="20dp"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><TextViewandroid:layout_width="90dp"android:layout_height="wrap_content"android:text="姓名:"android:textColor="@color/black"/><EditTextandroid:enabled="false"android:id="@+id/activity_autonym_certification_et_name"android:layout_width="match_parent"android:layout_height="wrap_content"android:textColor="@color/black"android:gravity="center"android:background="@drawable/autonym_certification_iv_line"android:text=""/></LinearLayout><LinearLayoutandroid:layout_marginTop="10dp"android:layout_marginLeft="30dp"android:layout_marginRight="30dp"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><TextViewandroid:layout_width="90dp"android:layout_height="wrap_content"android:text="有效日期:"android:textColor="@color/black"/><EditTextandroid:enabled="false"android:id="@+id/activity_autonym_certification_et_effective_date"android:layout_width="match_parent"android:layout_height="wrap_content"android:textColor="@color/black"android:gravity="center"android:background="@drawable/autonym_certification_iv_line"android:text=""/></LinearLayout><LinearLayoutandroid:layout_marginLeft="30dp"android:layout_marginRight="30dp"android:layout_marginTop="10dp"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><TextViewandroid:layout_width="90dp"android:layout_height="wrap_content"android:text="身份证号码:"android:textColor="@color/black"/><EditTextandroid:id="@+id/activity_autonym_certification_et_id_card"android:layout_width="match_parent"android:layout_height="wrap_content"android:textColor="@color/black"android:gravity="center"android:enabled="false"android:background="@drawable/autonym_certification_iv_line"android:text=""/></LinearLayout></LinearLayout></ScrollView></LinearLayout>

然后是两个实体类用来存放身份证正反两面的数据，先是正面

}

然后需要几个工具类

第一个bitmap编解码工具类

第二个网络请求工具类请求腾讯的接口

package cn.vonce.doer.utils;import android.util.Log;import org.xutils.common.Callback;
import org.xutils.http.RequestParams;
import org.xutils.x;import java.io.File;import cn.vonce.doer.sign.Constant;
import cn.vonce.doer.sign.YoutuSign;/*** 网络请求工具类*/
public class TecentHttpUtil {public static void uploadIdCard(String bitmap, String card_type, final SimpleCallBack callback) {StringBuffer mySign = new StringBuffer("");YoutuSign.appSign(Constant.AppID, Constant.SecretID, Constant.SecretKey,System.currentTimeMillis() / 1000 + Constant.EXPIRED_SECONDS,Constant.QQNumber, mySign);RequestParams params = new RequestParams("http://api.youtu.qq.com/youtu/ocrapi/idcardocr");params.setAsJsonContent(true);params.addHeader("accept", "*/*");params.addHeader("Host", "api.youtu.qq.com");params.addHeader("user-agent", "youtu-java-sdk");params.addHeader("Authorization", mySign.toString());params.addHeader("Content-Type", "text/json");params.addParameter("card_type", Integer.valueOf(card_type));params.addBodyParameter("image", bitmap);params.addBodyParameter("app_id", Constant.AppID);x.http().post(params, new Callback.CommonCallback<String>() {@Overridepublic void onSuccess(String result) {Log.d("onSuccess",result);callback.Succ(result);}@Overridepublic void onError(Throwable ex, boolean isOnCallback) {Log.d("onError",ex.getMessage());}@Overridepublic void onCancelled(CancelledException cex) {Log.d("onCancelled", cex.getMessage());}@Overridepublic void onFinished() {}});}public interface SimpleCallBack {void Succ(String result);void error();}}

在网络请求工具类里面会用到你申请的id了需要几个类
