TabLayout滑动

XML:

<android.support.design.widget.TabLayout
    android:id="@+id/mytab"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
</android.support.design.widget.TabLayout>
<android.support.v4.view.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</android.support.v4.view.ViewPager>

Activity:

public class Fragment2 extends Fragment{

    private View view;
    private TabLayout mytab;
    private ViewPager vp;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.fragment2,null);
        mytab =(TabLayout) view.findViewById(R.id.mytab);
        vp = (ViewPager) view.findViewById(R.id.viewpager);
        initData();
        return view;
    }

    private void initData() {
        List<Fragment> list = new ArrayList<>();
        list.add(new OneFragment());
        list.add(new OneFragment());
        list.add(new OneFragment());
        list.add(new OneFragment());
        list.add(new OneFragment());
        list.add(new OneFragment());

        MyFragmentAdapter myFragmentAdapter = new MyFragmentAdapter(getFragmentManager());
        myFragmentAdapter.setFragment(list);
        vp.setAdapter(myFragmentAdapter);
        for (int i = 0;i<5;i++){
            mytab.addTab(mytab.newTab());
        }
        mytab.setupWithViewPager(vp);
        mytab.getTabAt(0).setText("本地");
        mytab.getTabAt(1).setText("生活");
        mytab.getTabAt(2).setText("新闻");
        mytab.getTabAt(3).setText("娱乐");
        mytab.getTabAt(4).setText("游戏");
        mytab.getTabAt(5).setText("北京");
        mytab.setTabMode(TabLayout.MODE_SCROLLABLE);

    }
}

创建一个FragmentAdapter类:

public class MyFragmentAdapter extends FragmentPagerAdapter{
    public MyFragmentAdapter(FragmentManager fm) {
        super(fm);
    }
    List<Fragment> lists;

    public void setFragment(List<Fragment> list){
        lists = list;
    }

    @Override
    public Fragment getItem(int position) {
        return lists.get(position);
    }

    @Override
    public int getCount() {
        return lists.size();
    }
}
