3. 发起支付

3.1 微信支付

   /**
     * 微信支付
     * @param pay_param 支付服务生成的支付参数
     */
    private void doWXPay(String pay_param) {
        String wx_appid = "wx6b69bdbf2adca4f8";     //替换为自己的appid
        WXPay.init(getApplicationContext(), wx_appid);      //要在支付前调用
        WXPay.getInstance().doPay(pay_param, new WXPay.WXPayResultCallBack() {
            @Override
            public void onSuccess() {
                Toast.makeText(getApplication(), "支付成功", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onError(int error_code) {
                switch (error_code) {
                    case WXPay.NO_OR_LOW_WX:
                        Toast.makeText(getApplication(), "未安装微信或微信版本过低", Toast.LENGTH_SHORT).show();
                        break;

                    case WXPay.ERROR_PAY_PARAM:
                        Toast.makeText(getApplication(), "参数错误", Toast.LENGTH_SHORT).show();
                        break;

                    case WXPay.ERROR_PAY:
                        Toast.makeText(getApplication(), "支付失败", Toast.LENGTH_SHORT).show();
                        break;
                }
            }

            @Override
            public void onCancel() {
                Toast.makeText(getApplication(), "支付取消", Toast.LENGTH_SHORT).show();
            }
        });
    }

3.2 支付宝支付

   /**
     * 支付宝支付
     * @param pay_param 支付服务生成的支付参数
     */
    private void doAlipay(String pay_param) {
        new Alipay(this, pay_param, new Alipay.AlipayResultCallBack() {
            @Override
            public void onSuccess() {
                Toast.makeText(getApplication(), "支付成功", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onDealing() {
                Toast.makeText(getApplication(), "支付处理中...", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onError(int error_code) {
                switch (error_code) {
                    case Alipay.ERROR_RESULT:
                        Toast.makeText(getApplication(), "支付失败:支付结果解析错误", Toast.LENGTH_SHORT).show();
                        break;

                    case Alipay.ERROR_NETWORK:
                        Toast.makeText(getApplication(), "支付失败:网络连接错误", Toast.LENGTH_SHORT).show();
                        break;

                    case Alipay.ERROR_PAY:
                        Toast.makeText(getApplication(), "支付错误:支付码支付失败", Toast.LENGTH_SHORT).show();
                        break;

                    default:
                        Toast.makeText(getApplication(), "支付错误", Toast.LENGTH_SHORT).show();
                        break;
                }

            }

            @Override
            public void onCancel() {
                Toast.makeText(getApplication(), "支付取消", Toast.LENGTH_SHORT).show();
            }
        }).doPay();
    }
