我是安卓新手。我正在尝试FriendsList从Facebook. 我没有得到好友列表，因为我从 json 数组获得的数据始终为空。我已阅读有关设置权限以检索好友列表的信息，但我不明白在哪里以及如何设置它。谁能帮我解决这个问题。由于我是初学者，请逐步指导我。我的代码如下：
我添加了缺少的权限，如下所示：
mFacebook.authorize(MainActivity.this, new String[] { "user_friends" },
new LoginDialogListener());
但结果仍然为空。
MainActivity.java
public Facebook mFacebook = new Facebook(mAPP_ID);
public void getme()
{
// TODO Auto-generated method stub
Session activeSession = mFacebook.getSession();
if(activeSession.getState().isOpened())
{
final AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(mFacebook);
mAsyncRunner.request("me/friends", new FriendListRequestListener());
}
}
FriendsListRequestListener.java
public class FriendListRequestListener implements RequestListener {
@Override
public void onComplete(String response, Object state) {
// TODO Auto-generated method stub
try
{
JSONObject json = Util.parseJson(response);
final JSONArray friends = json.getJSONArray("data");
Log.i("jjj",""+friends);
}
catch(JSONException exception)
{
Log.e("err", ""+exception.toString());
}
}
@Override
public void onIOException(IOException e, Object state) {
// TODO Auto-generated method stub
}
@Override
public void onFileNotFoundException(FileNotFoundException e, Object state) {
// TODO Auto-generated method stub
}
@Override
public void onMalformedURLException(MalformedURLException e, Object state) {
// TODO Auto-generated method stub
}
@Override
public void onFacebookError(FacebookError e, Object state) {
// TODO Auto-generated method stub
}
}
