推荐答案

根据此:

要检查用户是否已登录，请调用isConnected().

To check if the user is signed-in, call isConnected().

if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
   // signed in. Show the "sign out" button and explanation.
   // ...
} else {
   // not signed in. Show the "sign in" button and explanation.
   // ...
}
