在android中加载google plus中特定的可见人

我已经成功实施了google plus

列出人员活动

@Override

在上面的代码中mPlusClient.loadVisiblePeople(this, null);加载所有可见（圈内）人员..我想加载我圈子中的一个特定人员。和mPlusClient.loadPeople(this, "103193341800315457743");这可以加载特定的人，但我怎么知道它是否在我的圈子中......因为它每次都会返回，无论它是否在我的圈子中。

其实我想知道特定的人是否在我的圈子里。

try, mPlusClient.loadPerson(这, "103193341800315457743");
