获取所有用户圈子，然后将人员加入Google Plus android

Question

您好我正在努力获得Google plus帐户的所有圈子。我使用Google Plus登录按钮验证了我的应用。

现在我想访问登录用户拥有的所有圈子 Circle Information Link

如何获取Google plus api for android的圈子列表

Answer 1

To get list of circles：

import java.util.List;
import com.google.api.services.plusDomains.model.Circle;
import com.google.api.services.plusDomains.model.CircleFeed;

PlusDomains.Circles.List listCircles = plusDomains.circles().list("me");
listCircles.setMaxResults(5L);
CircleFeed circleFeed = listCircles.execute();
List<Circle> circles = circleFeed.getItems();

// Loop until no additional pages of results are available.
while (circles != null) {
  for (Circle circle : circles) {
    System.out.println(circle.getDisplayName());
  }

  // When the next page token is null, there are no additional pages of
  // results. If this is the case, break.
  if (circleFeed.getNextPageToken() != null) {
    // Prepare the next page of results
    listCircles.setPageToken(circleFeed.getNextPageToken());

    // Execute and process the next page request
    circleFeed = listCircles.execute();
    circles = circleFeed.getItems();
  } else {
    circles = null;
  }
}

To get people inside circles：

import com.google.api.services.plusDomains.model.PeopleFeed;

String circleId = "a1234b";

PlusDomains.People.ListByCircle listPeople = plusDomains.people().listByCircle(circleId);
listPeople.setMaxResults(100L);

PeopleFeed peopleFeed = listPeople.execute();
System.out.println("Google+ users circled:");

// This example only displays one page of results.
if(peopleFeed.getItems() != null && peopleFeed.getItems().size() > 0 ) {
  for(Person person : peopleFeed.getItems()) {
    System.out.println("\t" + person.getDisplayName());
  }
}
