拿起FB朋友的生日

Question

我遇到了一些问题。这是从我的FB配置文件中获取数据的主要活动。在执行此操作后，将启动另一个活动，并且listview和我的fb朋友列表之间存在联接。当我试图获得他们的生日日期时，活动仅选择一个生日。你可以说＆＃34;老兄，生日并不总是公开的＃34;没错，但是如果我有一个朋友，我可以访问他/她的所有数据，看起来很奇怪，只有600多个朋友中的一个人有公开生日。所以我开始认为问题可能是权限问题。你有什么建议？

public class MainActivity extends FragmentActivity {
SharedPreferences sp;
AccessToken token;
private Button connect;
private String id, name, surname, date, access_token, expires;

@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    connect=(Button)findViewById(R.id.authButton);

    connect.setOnClickListener(new OnClickListener() 
    {
        @Override
        public void onClick(View arg0) 
        {
                openFacebook();
        }
    });

    sp=getPreferences(MODE_PRIVATE);
    access_token=sp.getString("access_token", null);
    expires=sp.getString("access_expires",null);

    if (access_token!=null  && expires!=null)
    {
        token = AccessToken.createFromExistingAccessToken(access_token,null, null, AccessTokenSource.TEST_USER, null);
        if (token!=null)
        {
            connect.setVisibility(View.INVISIBLE);
            Session.openActiveSessionWithAccessToken(this,token,new Session.StatusCallback() 
            {
                // callback when session changes state
                @Override
                public void call(final Session session, SessionState state, Exception exception) 
                {
                    if (session.isOpened()) 
                        doRequest(session);
                }
            });
        }  
    }    
}



@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

private void openFacebook()
{
    Session.openActiveSession(this, true, new Session.StatusCallback()
    {   
        // callback when session changes state
        @Override
        public void call(final Session session, SessionState state, Exception exception) 
        {
            if (session.isOpened()) 
            {
                Editor editor = sp.edit();
                editor.putString("access_token",session.getAccessToken());
                editor.putString("access_expires",session.getExpirationDate().toString());
                editor.commit();

                doRequest(session);
            }

        }
    }); 
}

public void doRequest(Session session)
{
    Request request =  Request.newMeRequest(session, new GraphUserCallback() 
    {       
        public void onCompleted(GraphUser user, Response response) 
        {                                
            if (user != null) 
            {
                Intent myIntent = new Intent(MainActivity.this, LoggedActivity.class);
                /*user stuff saved in intent*/
                startActivity(myIntent);
            }                
        }
    });

    Request.executeBatchAsync(request);
}

}
