调用viewPager.setAdapter

Question

当我致电mViewPager.setAdapter时，我的应用停止响应。一旦发生这种情况，LOGCAT会多次输出以下消息：

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

        View inflatedView = inflater.inflate(R.layout.fragment_options, container, false);
        mViewPager = (ViewPager) inflatedView.findViewById(R.id.viewpager_options);
        mViewPager.setAdapter(new Adapter(getChildFragmentManager()));

        return inflatedView;
    }

    private class Adapter extends FragmentPagerAdapter {

        private static final int TABS = 3;

        public Adapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            switch (position){
                case 0: return new OptionsFragment();
                default: return new OptionsFragment();
            }
        }

        @Override
        public int getCount() {
            return TABS;
        }
    }

@Override
        public Fragment getItem(int position) {
            switch (position){
                case 0: return new OptionsFragment();
                default: return new OptionsFragment();
            }
        }

为什么OptionsFragment包含OptionsFragment。它的循环视图
