listview数据源有数据，但是不显示数据

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View v = inflater.inflate(R.layout.fragment_first, container, false);
    ViewUtils.inject(this,v);
    initView();
    loadData();
    return v;
}
在fragment里调用的xutils第三方库，返回的view应该是这样
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
  //  View v = inflater.inflate(R.layout.fragment_first, container, false);
    ViewUtils.inject(this,inflater.inflate(R.layout.fragment_first, container, false));
    initView();
    loadData();
    return inflater.inflate(R.layout.fragment_first, container, false);
}
