1、首先到微信.开放平台创建账号，登录
微信开放平台：https://open.weixin.qq.com/
2、创建应用，申请微信支付权限
申请通过，填写 资料审核——审核通过如下：
3、微信支付 入驻申请通过会受到邮件如下：两个支付要用到的参数，商户号和APPID
这是点击前往操作，进入微信支付。商户平台
点击设置密钥，完成设置密钥并保持密钥，这个密钥是微信支付的第三个参数，也是最后一个参数。
只需APPID 、商户号、密钥；三个参数即可完成微信支付
4、微信支付六个工具类：

5、配置微信activity
<activityandroid:name=".wxapi.WXEntryActivity"android:configChanges="keyboardHidden|orientation|screenSize"android:exported="true"android:screenOrientation="portrait"android:theme="@android:style/Theme.Translucent.NoTitleBar" /><activityandroid:name=".wxapi.WXPayEntryActivity"android:exported="true"android:launchMode="singleTop" />
