onclicklistener不在片段内工作

Question

我用按钮创建了一个片段，但单击按钮时没有调用onclicklistener。

这是我的片段类代码

public class UserEntryFragment extends Fragment implements OnClickListener {

    EditText member_num,password;
    Button submit;
    ProgressBar progressBar;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    View view = inflater.inflate(R.layout.main,container, false);
    member_num = (EditText) view.findViewById(R.id.member_num);
    password = (EditText) view.findViewById(R.id.password);
    submit = (Button) view.findViewById(R.id.submit);
    progressBar = (ProgressBar) view.findViewById(R.id.progressBar1);
    submit.setOnClickListener(this);
    return view;
}
   @Override
   public void onClick(View view) {
    // TODO Auto-generated method stub
    if (view == submit) {
        System.out.println("Button Clicked");
    }
}

我错过了什么或者做错了吗？

提前谢谢。
