在左侧侧拉栏目中对控件添加事件监听，但点击后没有反应，什么原因？

public class LeftMenuFragment extends BaseFragment {
private ImageView headimage;
private String id;

@Override
public View initView(LayoutInflater inflater) {


    View view = inflater.inflate(R.layout.left_menu, null);
    ViewUtils.inject(this, view); // 把当前view对象注入到xUtils框架中.
    Button exit=(Button) view.findViewById(R.id.back_application);
    ImageView head_view = (ImageView) view.findViewById(R.id.head_view);

    exit.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            System.exit(0);

        }
    });

    return view;

}


@Override
 public void initData() {

}

public void setdata(String id) {
 this.id=id;
 System.out.println("w我就像看看可能传过来"+id);
 }
 }
