关于在fragment中加入viewpager的问题，请指教。。

Question

public class FragmentCategory extends Fragment{

//声明viewpager
private ViewPager viewPager;
//声明数据源
private List<Fragment> list;
//声明适配器
private FragmentStatePagerAdapter adapter;
//声明view
private View view;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view=inflater.inflate(R.layout.fragment_category, container, false);
    init();
    return view;
}

//初始化控件的方法
private void init() {
    // TODO Auto-generated method stub

    //得到viewpager
    viewPager=(ViewPager) view.findViewById(R.id.viewpager_tab);
    //得到列表
    list=new ArrayList<Fragment>();
    //往列表里添加fragment
    Information information=new Information();
    Market market=new Market();
    Circle circle=new Circle();
    list.add(information);
    list.add(market);
    list.add(circle);
    //声明适配器
    adapter=new FragmentStatePagerAdapter(getChildFragmentManager()) {

        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return list.size();
        }

        @Override
        public Fragment getItem(int arg0) {
            // TODO Auto-generated method stub
            return list.get(arg0);
        }

        @Override
        public Object instantiateItem(ViewGroup arg0, int arg1) {
            // TODO Auto-generated method stub
            return super.instantiateItem(arg0, arg1);
        }

        @Override
        public void destroyItem(ViewGroup container, int position,
                Object object) {
            // TODO Auto-generated method stub
            super.destroyItem(container, position, object);
        }
    };

    viewPager.setAdapter(adapter);
}

}

log日志报的错
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.yanis.yc_ui_fragment_menu/com.yanis.yc_ui_fragment_menu.MainActivity}: android.view.InflateException: Binary XML file line #13: Error inflating class fragment

仔细检查了XML文件，没有发现问题。。。求大神指教下。。

MainActivity 布局 第 13行有错误 。fragment tag 可能不对；
