Android 支付宝，微信支付
https://docs.open.alipay.com/204
https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=8_1
1、配置
android { compileSdkVersion 27 defaultConfig { resValue("string", "wx_appid", "wxa----------------") //此处填入自己appid,必须 }}dependencies { implementation 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:5.1.4' //微信支付 implementation files('libs/alipaySdk-xxxx.jar') //支付宝}2、复制资源
1、支付宝jar包下载地址：https://docs.open.alipay.com/54/104509
（此资源较敏感，防止第三方修改，本文不提供，仅提供官网下载地址，下载后放入[project]/[model]/libs目录中，1中引用需要修改为jar包名称）。
2、在主包下面新建包wxapi,新建类WXPayEntryActivity.java
package com.xxx.wxapi;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.util.Log;import com.xxx.utils.PayUtils;import com.tencent.mm.opensdk.constants.ConstantsAPI;import com.tencent.mm.opensdk.modelbase.BaseReq;import com.tencent.mm.opensdk.modelbase.BaseResp;import com.tencent.mm.opensdk.openapi.IWXAPI;import com.tencent.mm.opensdk.openapi.IWXAPIEventHandler;import com.tencent.mm.opensdk.openapi.WXAPIFactory;/** * Created by 林少 on 2016/6/22. */public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler { public IWXAPI api; public static PayUtils.WxPayNotify notify; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); api = WXAPIFactory.createWXAPI(this, getString(getResources().getIdentifier("wx_appid", "string", getPackageName()))); 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) { if (resp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) { if (resp.errCode == 0) { notify.success(); } else { notify.failure(); } finish(); } }}AndroidManifest.xml添加
3、将下面工具类放入项目中,代码为kotlin编写，如需要转换为java，请留言

支付宝
//back.data为后台返回PayUtils.alipayPay(this@PayVipActivity, back.data, object : PayUtils.AlipayNotify { override fun success() { T("支付成功") finish() } override fun loadinging() { T("支付结果确认中，请勿返回") } override fun failure() { T("支付失败，请重试") } })微信
//back.data为后台返回签名过的对象PayUtils.wxPayMethod(this@PayVipActivity, back.data, object : PayUtils.WxPayNotify { override fun success() { T("支付成功") finish() } override fun failure() { T("支付失败，请重试") } })出现错误请检查配置先，微信支付错误如果返回失败，自己debug看log,如果是-1，先检查开放平台包名和签名，如果正确说明后台签名错误，请把次链接给他，zzzz,https://www.jianshu.com/p/332e2e968c2b
