Question

我正在尝试从我的代码访问listview和textview，我在互联网上阅读了很多帖子，但我找不到任何适合我的帖子。我有一个这样的空白片段：

public class MyFrag extends Fragment {

//My Code
List<String> Names = new ArrayList<String>();
List<Double> Prices = new ArrayList<Double>();
List<String> Dates =  new ArrayList<String>();
List<String> Hours =  new ArrayList<String>();
List<String> iDs =  new ArrayList<String>();
Double TotalMy = 0.00;
SimpleAdapter adapter;



public MyFrag() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    //RelativeLayout rootView = (RelativeLayout) inflater.inflate(R.layout.fragment_my_frag, container, false);
    //View view = inflater.inflate(R.layout.fragment_my_frag, container, false);

    LayoutInflater lf = getActivity().getLayoutInflater();

    View view = lf.inflate(R.layout.fragment_my_frag, container, false);


    ListView listview = (ListView) getView().findViewById(R.id.list);
    TextView textTotalMy = (TextView) getView().findViewById(R.id.textTotalMy1);


    return view;

}

但是当我打开片段时，应用程序崩溃了。

请帮帮我

Answer 1

我通过编程方式创建相同的相对布局来解决它

访问Java中的片段布局对象不起作用
