1. WxPayFace.getInstance().initWxpayface(LoginActivity.this, m1, new IWxPayfaceCallback() { @Override public void response(Map info) throws RemoteException { if (!Tools.isSuccessInfo(info)) { return; ToastUtil.show"初始化完成" }) 2. WxPayFace.getInstance().startCodeScanner(new IWxPayfaceCallback() { @Override public void response(Map info) throws RemoteException { Log.TAG, "response: ==" + info) if (Tools.isSuccessInfo(info)) { String code_msg = (String) info.get(Constants.CODE_MSG ToastUtil.show"获取到二维码信息" + code_msg) } else Log.TAG, "response: " + info) ToastUtil.show"扫码失败" } }) 在第二步后面的log没有任何打印

好的
