我开始从事 Java/Android 开发。我正在制作一个带有多个选项卡和滑动导航的调查类型应用程序。（基于 SDK/eclipse 示例）。

我有一个片段（选项卡）用一些微调器为视图充气，我需要在另一个片段中创建一个重置按钮，将所有微调器重置到位置 0。

带有微调器的片段。

public class Viagem extends Fragment
{


 public Spinner spinLinhaO;


    public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    }

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState)
{
    View view2 = inflater.inflate(R.layout.activity_viagem, container, false);

     final Spinner spinLinhaO = (Spinner) view2.findViewById(R.id.spinnerO1);

        // with the adapter to populate it 

 }

带有按钮的片段。

    public class Inicio extends Fragment
{ 

    @Override
        public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState)
    { 

        View view3 = inflater.inflate(R.layout.activity_menu, container, false);


        final Button button = (Button) view3.findViewById(R.id.buttonInq);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view3) { 
         Viagem.spinLinhaO.setSelection(0); //this does not work
 }

你能帮我解决这个问题吗？
