}span stylefont-family: Arial, Helvetica, sans-serif;前面的几个常量是需要去支付宝官网获取的获取后直接替换就ok /span
其他的代码基本都是从demo中copy出来的 现在我们就将支付功能封装到了一个类中那么如何使用呢Alipay alipay new Alipay(OrderConfirmActivity.this);
alipay.setListener(mAlipayListener);
alipay.pay(desc, mOrder.getShopName(), String.valueOf(orderAmount), orderSn, url);
/*** 支付宝支付回调*/
private Alipay.OnAlipayListener mAlipayListener new Alipay.OnAlipayListener() {Overridepublic void onSuccess() {onOrderSubmitSuccess();}Overridepublic void onCancel() {onUserOrderCanceled();Toast.makeText(OrderConfirmActivity.this, R.string.pay_failed, Toast.LENGTH_SHORT).show();}Overridepublic void onWait() {}
};
new出对象来只需要调用pay方法就ok啦 不过支付的回调我们还是必须的当然这个也不麻烦。这里说一下pay方法的几个参数 title 支付的标题
desc 支付的描述
price 支付的金额
sn 商品的唯一货号
url 服务器的回调url
这几个参数在做支付的时候服务器都会给到但是要注意一下这几个参数都不能为空或者空字符串否则会支付失败。
