Answer 1

接下来，您必须使用Intent开始登录流程。

public void startSignIn(){
    Intent signInIntent =     Auth.GoogleSignInApi.getSignInIntent(.   mGoogleApiClient);
            startActivityForResult(signInIntent,     GOOGLE_SIGN_IN);
}

现在实现onActivityResult（）以获得结果。

public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // Result returned from launching the Intent.
        if (requestCode == GOOGLE_SIGN_IN && resultCode == RESULT_OK) {
            GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
            handleSignInResult(result);
        }
    }

现在您可以从结果对象中获取帐户详细信息。

private void     handleSignInResult(GoogleSignInResult result) {
    //Check if signin result is successful
    if (result.isSuccess()) {
        // Signed in successfully.
        GoogleSignInAccount acct =     result.getSignInAccount();
                testView.setText(acct.getDisplayName());
Uri profilePictureUri = acct.getPhotoUrl();
//You can get other details like email,Id etc.
      
    } else {
        // Signed out.
       
    }
}
