TabLayout使用

public class AFragment extends Fragment  {    private View view;    private TabLayout tabLayout;    private ViewPager viewPager;    private List fragmentList;    private List list;    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container,                             Bundle savedInstanceState) {        //加载布局 及资源id        view = inflater.inflate(R.layout.fragment_a, container, false);        tabLayout = (TabLayout) view.findViewById(R.id.tab_layout);        viewPager = (ViewPager) view.findViewById(R.id.vp);                        return view;    }    @Override    public void onActivityCreated(@Nullable Bundle savedInstanceState) {        super.onActivityCreated(savedInstanceState);        //viewPage 添加数据        fragmentList = new ArrayList<>();        fragmentList.add(new BFragment());        fragmentList.add(new CFragment());        //tabLayout 添加数据        list = new ArrayList<>();        list.add("中信人报");        list.add("专门");                tabLayout.addTab(tabLayout.newTab().setText(list.get(0)));        tabLayout.addTab(tabLayout.newTab().setText(list.get(1)));        tabLayout.setTabMode(TabLayout.MODE_FIXED);        Adapter_ViewPage adapter = new Adapter_ViewPage(getFragmentManager());        viewPager.setAdapter(adapter);        tabLayout.setTabsFromPagerAdapter(adapter);        tabLayout.setupWithViewPager(viewPager);    }      class Adapter_ViewPage extends FragmentPagerAdapter {        public Adapter_ViewPage(FragmentManager fm) {            super(fm);        }           @Override        public CharSequence getPageTitle(int position) {            return list.get(position);        }        @Override        public int getCount() {            return fragmentList.size();        }        @Override        public boolean isViewFromObject(View view, Object object) {            return true;        }        @Override        public Fragment getItem(int position) {            return fragmentList.get(position);        }/*      使用PagerAdapter适配器 会移动这两个方法        @Override        public Object instantiateItem(ViewGroup container, int position) {            TextView textView = new TextView(getActivity());            return textView;        }        @Override        public void destroyItem(ViewGroup container, int position, Object object) {            container.removeView((View) object);        }*/    }}
