Activity中回调 (写在点击事件中)

PayPurchaDialog dialog = new PayPurchaDialog(mContext);//支付密码弹出框
                dialog.setOnOkClick(new PayPurchaDialog.OnOkClick() {
                    @Override
                    public void onOkClick(String payPwd) {
                        //TODO:点击确定, 密码回调在这里  先判断密码，然后调用接口
                         dialog.dismiss(); //关闭窗口
                      //带着密码payPwd调用你的方法
                    
                    }
                });
                dialog.show();
