            // Signed in successfully, show authenticated UI.
            Log.e(TAG, "account--------------->>>" + account.getEmail() + " ," + account.getAccount() + " ," );
            String displayName = account.getDisplayName();
            String msg = "欢迎"+displayName+", 登录成功！";
            ToastUtil.successShortToast(msg);
        } catch (ApiException e) {
            // The ApiException status code indicates the detailed failure reason.
            // Please refer to the GoogleSignInStatusCodes class reference for more information.
            Log.e(TAG, "signInResult:failed code=" + e.getStatusCode() + "  " + GoogleSignInStatusCodes.getStatusCodeString(e.getStatusCode()));
