Android 集成微信支付和支付宝

来源：互联网发布：linux 显示执行过程编辑：程序博客网时间：2024/05/21 20:26

最近比较闲，公司项目更换后台，于是自己来研究微信支付和支付宝支付，把自己学习的过程写下来，以备以后查看。

注：要集成微信支付和支付宝功能，必须要有以下几个配置信息，而这写信息需要公司去微信支付和支付宝开放平台申请并提供给开发者，当然自己也可以去申请，这里作者用的是公司提供的，这里不纠结这些过程。获得这些信息以后

将配置信息放到一个静态类中，以共统一使用，但是处于安全考虑，微信与支付宝推荐这些数据放到服务器，这里作者把他们都放在前端，整个过程都是前端处理，实际开发尽量预处理订单生成放到后端处理。

1.微信支付的集成前提条件

1.首先需要导入微信jar包，从开放平台可以下载到，加入到libs目录即可
2.配置manifest

?

a.用户权限

<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></uses-permission></uses-permission>

b.activity配置，这里com.gan.mypay改成自己的包名（如果自己包名与src下的package 名不一样，这里要的是在manifest中配置的名称，同样需要在src建立以自己包名为路劲的package,一定确保有这个activity）这个activity是微信支付结果要回调的activty

2.支付宝支付的集成前提条件

<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></uses-permission></uses-permission>

b.activity配置这里必须要这么配置

3.代码集成

1.首先要有个商品页面MainActivity，用来手机收集商品信息，这里需要后台交互生成订单，我偷懒就直接在页面生成了假订单

MainActivity.java(这里用了xutils的注入)

Android 集成微信支付和支付宝

1.微信支付的集成前提条件

1.首先需要导入微信jar包，从开放平台可以下载到，加入到libs目录即可2.配置manifest

2.支付宝支付的集成前提条件

1.首先需要导入微信jar包，从开放平台可以下载到，加入到libs目录即可2.配置manifest

3.代码集成

1.首先要有个商品页面MainActivity，用来手机收集商品信息，这里需要后台交互生成订单，我偷懒就直接在页面生成了假订单

2.在mainactivty中点击确认按钮调用支付方式选择页面SelectPayTypeActivity，用来发起支付选择

3.根据支付方式调用对应工具类微信（WXpayUtil），支付宝（AlipayUtil）

1.首先需要导入微信jar包，从开放平台可以下载到，加入到libs目录即可
2.配置manifest
