Android 实施谷歌游戏服务-如何让用户登录
这是我第一次使用谷歌API，因为我对android编程相当陌生。我一直在尝试在我的应用程序中实现google play游戏服务和显示排行榜（你可能已经猜到了，这是一个游戏），但在跟随google的文档时遇到了一些困难 我已经设置了一个按钮，我想让用户登录时，点击它，并留下用户登录，直到他们注销后。我已按照以下文件对此进行了编程：Android 实施谷歌游戏服务-如何让用户登录,android,google-api,google-play-games,google-api-client,Android,Google Api,Google Play Games,Google Api Client,这是我第一次使用谷歌API，因为我对android编程相当陌生。我一直在尝试在我的应用程序中实现google play游戏服务和显示排行榜（你可能已经猜到了，这是一个游戏），但在跟随google的文档时遇到了一些困难 我已经设置了一个按钮，我想让用户登录时，点击它，并留下用户登录，直到他们注销后。我已按照以下文件对此进行了编程： public class MainActivity extends AppCompatActivity implements View.OnClickListener,

非常感谢您的帮助，因为除了谷歌的文档之外，我还没有找到任何关于这方面的教程，正如我前面所说，我很难理解和理解这些文档。这对我来说是正确的
