Android中的Google Plus封面照片

Question

我正在尝试使用以下代码获取Google plus封面照片：

if (Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) != null) 
{
  Person currentPerson = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
  String personName = currentPerson.getDisplayName();
  String userId = currentPerson.getId();
  personPhotoUrl = currentPerson.getImage().getUrl();
  String personGooglePlusProfile = currentPerson.getUrl();

  boolean coverphoto = currentPerson.getCover().hasCoverPhoto();

  String urlBackgroud = currentPerson.getCover().getCoverPhoto().getUrl();

  String email = Plus.AccountApi.getAccountName(mGoogleApiClient);
   Log.e("url","Background"+photo);
   Log.e(TAG, "Name: " + personName + ", plusProfile: "
                    + personGooglePlusProfile + ", email: " + email
                    + ", Image: " + personPhotoUrl + ", userId: " + userId );

设置好封面照片后。 我得到URL的结果，但没有设置封面照片，然后出现以下错误

然后我尝试了：

boolean coverphoto = currentPerson.getCover().hasCoverPhoto();

我仍然收到上述错误。 如何解决用户未设置封面照片的问题？

谢谢！

当您的Google客户端连接时，您需要拨打额外的电话，如下所示：

if (mGoogleApiClient.isConnected()) {
Plus.PeopleApi.load(mGoogleApiClient, person.getId())
                            .setResultCallback(new ResultCallback<People.LoadPeopleResult>() {
                        @Override
                        public void onResult(People.LoadPeopleResult loadPeopleResult) {
                            if (loadPeopleResult.getStatus().isSuccess()) {
                                PersonBuffer personBuffer = loadPeopleResult.getPersonBuffer();
                                if (personBuffer != null && personBuffer.getCount() > 0) {
                                    Person currentUser = personBuffer.get(0);
                                    personBuffer.release();
                                    Person.Cover cover = currentUser.getCover();
                                    if (cover != null) {
                                        Person.Cover.CoverPhoto coverPhoto = cover.getCoverPhoto();
                                        if (coverPhoto != null) {
                                            String userCoverPhotoUrl = coverPhoto.getUrl();
                                            Log.i("Main TAG", "Cover photo Url :" + userCoverPhotoUrl);

                                        }
                                    } else {
                                        Log.i("TAG NO COVER", "Person has no cover");
                                    }
                                }
                            }
                        }
                    });

}
