最近公司又又又接了一个新的需求，某银行和我们合作，银行的开发团队是外包性质，为了方便开发，需求方让我们提供一个微信，支付宝sdk，Native和hTMl的对接形式，顾写了如下：

本SDK不生成订单数据，完全模拟工作中正常交互

1.[SDK中build.gradle]引用微信支付宝JAR包

compile files('libs/wechat-sdk-android-with-mta-1.0.2.jar')//微信支付
    compile files('libs/alipaySdk-20180601.jar')//支付宝支付

2.在[SDK中]ANDROIDMAINFEST.XML中添加权限以及微信支持

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="SDK包名">
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <application
        android:allowBackup="true">
        <activity
            android:name="com.alipay.sdk.app.H5PayActivity"
            android:configChanges="orientation|keyboardHidden|navigation"
            android:exported="false"
            android:screenOrientation="behind"/>
        <activity
            android:name="com.alipay.sdk.auth.AuthActivity"
            android:configChanges="orientation|keyboardHidden|navigation"
            android:exported="false"
            android:screenOrientation="behind"/>
            <!-- 支付回调页面 -->
        <!--<activity
            android:name=".wxapi.WXPayEntryActivity"
            android:exported="true"
            android:launchMode="singleTop">
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:scheme="${WEATCH_APPID}" />
            </intent-filter>
        </activity>-->
        <!--<meta-data android:name="WEATCG_APPID" android:value="${WEATCH_APPID}"/>-->
    </application>
</manifest>

3.[SDK]创建一个枚举

 package 包名.bean;
/**
 * @author fuqinming
 *
 * 支付类型枚举
 */
public enum PayType {
    WEATCH_PAY ( "WEATCH_PAY" ), ALIAPY ( "ALIPAY" );
    private String name;

 // 构造方法
    private PayType(String name) {
        this.name = name;
    }

    public String getName() {
          return name;
  }
}

4.[SDK]微信支付宝支付公共返回Model

 package 包名.bean;

/**
 * @author fuqinming
 *
 * 支付返回处理
 */
public class PayResult {

    private int resultStatus;//支付返回状态
    private String msg;//信息
    private String sub_msg;//信息补充
    private PayType type;//类型

    public void setResultStatus(int resultStatus) {
        this.resultStatus = resultStatus;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public void setSub_msg(String sub_msg) {
        this.sub_msg = sub_msg;
    }

    public int getResultStatus() {
        return resultStatus;
    }

    public String getMsg() {
        return msg;
    }

    public void setType(PayType type) {
        this.type = type;
    }

    public String getSub_msg() {
        return sub_msg;
    }

    public PayType getType() {
        return type;
    }
}

5.[SDK]创建微信支付订单Model

 package 包名bean;

/*微信分享bean*/
public class WeachPayBeanVo{
    //微信开放平台审核通过的应用APPID
    private String appid;
    //随机字符串，不长于32位。推荐随机数生成算法
    private String noncestr;
    //扩展字段[package]
    private String packageValue;
    //签名
    private String sign;
    //商户号
    private String partnerid;
    //预支付交易会话ID
    private String prepayid;
    //时间戳
    private String timestamp;

   public String getAppid() {
        return appid;
    }

    public void setAppid(String appid) {
        this.appid = appid;
    }

    public String getNoncestr() {
        return noncestr;
    }

    public void setNoncestr(String noncestr) {
        this.noncestr = noncestr;
    }

    public String getPackageValue() {
        return packageValue;
    }

    public void setPackageValue(String packageValue) {
        this.packageValue = packageValue;
    }

   public String getSign() {
        return sign;
    }

   public void setSign(String sign) {
        this.sign = sign;
    }

    public String getPartnerid() {
        return partnerid;
    }

    public void setPartnerid(String partnerid) {
        this.partnerid = partnerid;
    }

    public String getPrepayid() {
        return prepayid;
    }

    public void setPrepayid(String prepayid) {
        this.prepayid = prepayid;
    }

    public String getTimestamp() {
        return timestamp;
    }

   public void setTimestamp(String timestamp) {
        this.timestamp = timestamp;
    }

    @Override
    public String toString() {
        return "{\"appid\":\""+appid+"\",\"noncestr\":\""+noncestr+"\",\"package\":\""+packageValue+"\",\"sign\":\""+sign+"\",\"partnerid\":\""+partnerid+"\",\"prepayid\":\""+prepayid+"\",\"timestamp\":\""+timestamp+"\"}";
    }
}

6.[SDK]支付帮助类

其实没多大用处，可能和自己刚开始的想法有关系，后面SDK导出的时候，忘记把他删除了，看各位需求吧，csdn排版一直是个心病，表示排版好难，有强迫症的我，还在研究如何好看

package 包名.utils;

import android.app.ActivityManager;
import android.content.ComponentName;
import android.content.Context;
import java.util.List;

/*支付帮助类*/
public class PayUtils {

    /*获取当前运行的activity名称*/
    public static String getRunningActivityName(Context context) {
        ActivityManager activityManager = (ActivityManager) context.getSystemService ( Context.ACTIVITY_SERVICE );
        String runningActivity = activityManager.getRunningTasks ( 1 ).get ( 0 ).topActivity.getClassName ();
        String contextActivity = runningActivity.substring ( runningActivity.lastIndexOf ( "." ) + 1 );
        return contextActivity;
    }

    /*获取当前运行的报名*/
    public static String getAppPackageName(Context context) {
        ActivityManager activityManager = (ActivityManager) context.getSystemService ( Context.ACTIVITY_SERVICE );
        List <ActivityManager.RunningTaskInfo> taskInfo = activityManager.getRunningTasks ( 1 );
        ComponentName componentInfo = taskInfo.get ( 0 ).topActivity;
        return componentInfo.getPackageName ();
    }

    /*判空*/
    public static boolean isEmpty(String str) {
        return null == str || "".equals(str.trim()) || "null".equals(str.trim());
    }
}

2.[DEMO]拷贝微信需要信息到DEMO，SDK可以不遗留相关信息

使用支付sdk

在setting.gradle

include ‘:app’,’:SDK名字’

1)class类

package DEMO包名.wxapi;

import android.app.Activity;
import android.content.Intent;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageManager;

 * 微信要求必须有该类
 */
public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler {

    private IWXAPI api;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate ( savedInstanceState );
        requestWindowFeature ( Window.FEATURE_NO_TITLE );
        String APP_ID = "";
        try {
            ApplicationInfo activityInfo = this.getPackageManager ().getApplicationInfo ( this.getPackageName (), PackageManager.GET_META_DATA );
            APP_ID = activityInfo.metaData.getString ( "WEATCG_APPID" );
        } catch (Exception e) {
        }
        if (null == APP_ID || "".equals ( APP_ID.trim () ) || "null".equals ( APP_ID.trim () )) {
            NullPointerException nullError = new NullPointerException ( "WEACH_APPID Value is not set, params is null" );
            throw nullError;
        }
        api = WXAPIFactory.createWXAPI ( this, APP_ID );
        api.handleIntent ( getIntent (), this );
    }

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent ( intent );
        setIntent ( intent );
        api.handleIntent ( intent, this );
    }

    @Override
    public void onReq(BaseReq req) {
    }

    @Override
    public void onResp(BaseResp resp) {
        //支付
        if (resp.getType () == ConstantsAPI.COMMAND_PAY_BY_WX) {
            int errCode = resp.errCode;
            Intent intent = new Intent ();
            intent.setAction ( "WEACHATPAY" );
            intent.putExtra ( "errCode", errCode + "" );
            sendBroadcast ( intent );
            WXPayEntryActivity.this.finish ();
        }
    }
}

2)androidMainFest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="DEMO包名">
    <uses-permission android:name="android.permission.INTERNET"/>

        <meta-data android:name="WEATCG_APPID" android:value="${WEATCH_APPID}"/>
    </application>
</manifest>

3)build.gradle

apply plugin: 'com.android.application'

android {
    signingConfigs {
        debug {
        }
    }
    compileSdkVersion 18
    buildToolsVersion '27.0.2'
    defaultConfig {
        applicationId "demo包名"
        minSdkVersion 20
        targetSdkVersion 18
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        manifestPlaceholders = [
                "WEATCH_APPID": "xxxxxxxxxxx",//加入自己的微信支付appid
        ]
    }
    buildTypes {
        debug {
            signingConfig signingConfigs.debug
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation 'com.android.support:appcompat-v7:18.0.0'
    implementation project(':sdk名称')
}

一切搞定，下面只需要调用即可

3.[DEMO]微信支付宝支付调用

1)PayTestActivity

package DEMO包名;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

/**
 *@author fuqinming
 *
 * 支付测试
 */
public class PayTestActivity extends Activity implements View.OnClickListener{
    private Button nativePay;
    private Button htmlPay;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate ( savedInstanceState );
        setContentView ( R.layout.layout_main );
        initView ();
        initActive ();
    }

    private void initView(){
        nativePay=(Button)findViewById ( R.id.native_pay );
        htmlPay=(Button)findViewById ( R.id.html_pay );
    }

    private void initActive(){
        nativePay.setOnClickListener ( this );
        htmlPay.setOnClickListener ( this );
    }

    @Override
    public void onClick(View v) {
        switch (v.getId ()){
            case R.id.native_pay://
                startActivity (new Intent ( PayTestActivity.this, PayNativeTestActivity.class ) );
                break;
            case R.id.html_pay:
                startActivity (new Intent ( PayTestActivity.this, PayWebActivity.class ) );
                break;
        }
    }
}

2）PayNativeTestActivity[自己调用自己]

package DEMO包名;

import android.os.Bundle;
import android.view.View;
import android.widget.Toast;
import com.google.gson.Gson;
import SDK包名.bean.PayResult;
import SDK包名.bean.PayType;
import SDK包名.bean.WeachPayBeanVo;
import SDK包名.utils.WeatchPayBaseActivity;

/**
 * @author fuqinming
 *         <p>
 *         原生调用自己支付
 */
public class PayNativeTestActivity extends WeatchPayBaseActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate ( savedInstanceState );
        setContentView ( R.layout.pay_native_layout );
    }

    /*微信支付[来源view onclick]*/
    public void weatchPay(View view) {
        String str = "{\"appid\":\"wx166312d102c5d680\",\"noncestr\":\"ade55409d1224074754035a5a937d2e0\",\"packageValue\":\"Sign=WXPay\",\"partnerid\":\"1489993422\",\"prepayid\":\"wx1516414346268735be1104e93980871271\",\"sign\":\"81BE92ED61E2E221BE5D3028E4E15AD3\",\"timestamp\":\"1529052103\"}";
        WeachPayBeanVo data = new Gson ().fromJson ( str, WeachPayBeanVo.class );
        wechatPay ( data );//微信支付
    }

    /*阿里支付[来源view onclick]*/
    public void aliPay(View view) {
        String order_str = "biz_content=%7B%22timeout_express%22%3A%2230m%22%2C%22product_code%22%3A%22QUICK_MSECURITY_PAY%22%2C%22total_amount%22%3A%220.01%22%2C%22subject%22%3A%221%22%2C%22body%22%3A%22%E6%88%91%E6%98%AF%E6%B5%8B%E8%AF%95%E6%95%B0%E6%8D%AE%22%2C%22out_trade_no%22%3A%220621105451-1654%22%7D&method=alipay.trade.app.pay&charset=utf-8&version=1.0&app_id=2017062807585767&timestamp=2016-07-29+16%3A55%3A53&sign_type=RSA&sign=LDfqg4VYEMxz0dtqy8SxNglfVDEync%2FeKSNByxxzpWU6e8w0cu7E6h4A%2B0uXQs31gAK%2Bp0KdwWwX7PYix%2BINPWujuMiQehsZQlS5L1t0QwhNp4vu8PYMYIdt6IVqTHxR3NxK3kp%2FZspJ0om3fAjV5hFvHgR%2BBcjQywqWBjmkeDiLJLhQDoujREq27veIqyCBGQ16a81FBDS2Hv1EiO4INjnE%2Ff3vBxXrUfYx2vBxQv9wwiqDg%2FOrxlG1a9SoFjC%2BnxnCFVkFQdSw4Z5ftMy7lDQFh2VyuzxTN2D%2FYgH%2B3cTIMzCiF7vTkfbBVIPmXarb6o8%2BJhVNGnxcjb0t9N2C9g%3D%3D";
        aliPay ( order_str );//阿里支付
    }

    /*支付回调*/
    public void payCallBackFunction(PayResult payResult) {
        super.payCallBackFunction ( payResult );
        PayType payType=payResult.getType ();
        String type=payType.getName ();
        if (payResult.getResultStatus () == 0) {
            Toast.makeText ( this, type+"支付成功", Toast.LENGTH_LONG ).show ();
        } else if (payResult.getResultStatus () == -1) {
            Toast.makeText ( this, type+"支付失败", Toast.LENGTH_LONG ).show ();
        } else if (payResult.getResultStatus () == -2) {
            Toast.makeText ( this, type+"用户取消", Toast.LENGTH_LONG ).show ();
        } else {
            Toast.makeText ( this, type+"未知错误，请检查环境配置", Toast.LENGTH_LONG ).show ();
        }
    }

    public void goback(View view){
        this.finish ();
    }
}

3)PayWebActivity[webview中html调用原生支付]

package DEMO包名

import android.os.Bundle;
import android.view.View;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import SDK包名.utils.WeatchPayBaseActivity;

/**
 * @author fuqinming
 *
 * html调用native支付
 */
public class PayWebActivity extends WeatchPayBaseActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate ( savedInstanceState );
        setContentView ( R.layout.pay_web_layout );
        WebView viewView=(WebView)findViewById ( R.id.view_webview );
        viewView.getSettings ().setJavaScriptEnabled ( true );
        addPayJavaScript(this,viewView);//添加webview支付支持
        String url="file:///android_asset/index.html";
        viewView.setWebChromeClient(new WebChromeClient ());//必须有这句话，否则html弹框无效
        viewView.loadUrl ( url );
    }

    public void goback(View view){
        this.finish ();
    }

}

这个需求就完成了，自己累记下，也方便后期自己开发
