hanfengzqh 2015-12-24 11:51:16

在WeChatFragment 类中点击退款
case R.id.button:
wechatRefundUtils = new WechatRefundUtils(mContext);
new Thread(){
@Override
public void run() {
try {
wechatRefundUtils.refundMoney(1);
} catch (Exception e) {
e.printStackTrace();
}
super.run();
}
}.start();
break;

在下面这个类里面具体执行退款操作：

但是运行过之后就会出现
