我正在做一个模块，我需要通过google plus登录用户。 我可以获得用户的姓名和电子邮件，但是在他/她的圈子中获得了人员列表。 有没有人知道如何获得人物圈子中的人员名单。??
这是我的代码。有些冗长..
public class SignIn extends Activity implements ResultCallback<People.LoadPeopleResult>,ConnectionCallbacks, OnConnectionFailedListener ,OnClickListener
{
//declaration of variables
static final String EMAIL_PATTERN =
"^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"

super.onCreate(savedInstanceState);
setContentView(R.layout.signin_layout);
//googleapiclient initialization..
mGoogleApiClient = new GoogleApiClient.Builder(this)

initializecontrols();
cancel.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
finish();
}
});
login.setOnClickListener(new OnClickListener() {

{
String em=email.getText().toString();
String ps=pswd.getText().toString();
if(em.length()==0||ps.length()==0)
{
Toast.makeText(getApplicationContext(), "Enter all the above", Toast.LENGTH_SHORT).show();

}
} finally {

根据教程onResult将在
时调用回调方法Plus.PeopleApi.loadVisible(mGoogleApiClient, null)
.setResultCallback(this);
此特定代码在OnConnected方法
中执行答案 0 :(得分：0)
您在提出请求后立即断开连接。
Google Play服务使用具有异步回调的客户端服务架构。断开连接实际上会关闭服务连接，从而阻止响应被传递给您。这类似于打电话给你的好友，说“嘿，怎么回事”，然后立即挂断你的手机。
顺便说一下，这里还有其他一些非标准的东西。一般来说，你应该在onStart（）中调用connect（你已经注释掉了）。如果用户已经授予了您的应用程序权限，那么您可以立即开始获取数据并使用它执行您想要的操作。如果用户未授予权限或存在其他问题（例如Kindle Fire，Google Play服务不可用），那么您将获得onConnectionFailed。然后，您可以保持该状态并在用户单击按钮时调用该分辨率。这将导致更快捷的UI，使您更容易匹配connect（）和disconnect（）调用。
通常应在onStop（）中调用disconnect（）。这样，在您的活动被拆除之前，您不会断开连接。
