Android-如何将意图意图的额外数据传递给ListFragment？

Question

当我想使用“ intenet put extra”传输字符串时出现错误，似乎第二个活动传递失败

主要活动

公共无效AbrirLista（）{

    Conversation conversationForUserList = pagerAdapter.getItem(pager.getCurrentItem()); 


    if (conversationForUserList.getType() == Conversation.TYPE_CHANNEL) {                   
        Intent intent = new Intent(this, SecondActivity.class);
        intent.putExtra(
                Extra.USERS,
                binder.getService().getConnection(server.getId()).getUsersAsStringArray(conversationForUserList.getName()));
        startActivityForResult(intent, REQUEST_CODE_USERS);
    } else {
        Toast.makeText(this, getResources().getString(R.string.only_usable_from_channel), Toast.LENGTH_SHORT).show();

}

    drawerLayout.openDrawer(drawerView);
} 

第二活动

public class SecondActivity extends ListFragment {


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final String[] users = getActivity().getIntent().getExtras().getStringArray(Extra.USERS);
        ListAdapter myListAdapter = new ArrayAdapter<String>(getActivity(),
                android.R.layout.simple_list_item_1, users);
        setListAdapter(myListAdapter);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        return inflater.inflate(R.layout.list, container, false);
    }


}

   Conversation conversationForUserList = pagerAdapter.getItem(pager.getCurrentItem()); 
  Intent intent = new Intent(this, SecondActivity.class);
   intent.putExtra("name_id",conversationForUserList);
    startActivity(intent);

    // get data to SecondActivity.class
    private Context context;
    private Conversation userList;
    private ArrayList<Conversation> users;
    userList = (Conversation) getActivity().getIntent().getSerializableExtra("name_id");
    users=conversationForUserList.getName(context);

     ListAdapter myListAdapter = new ArrayAdapter<String>(getActivity(),
            android.R.layout.simple_list_item_1, users);
      setListAdapter(myListAdapter);
