如何添加标签＆amp;片段动态？

我的代码：

    private void setupViewPager(ViewPager viewPager) {
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
    for (int i = 0; i < 4; i++) {
    adapter.addFrag(new TabFragment(), "Tab"+i);
     }
    viewPager.setAdapter(adapter);
     }

class ViewPagerAdapter extends FragmentPagerAdapter {
    private final List<Fragment> mFragmentList = new ArrayList<>();
    private final List<String> mFragmentTitleList = new ArrayList<>();

    public ViewPagerAdapter(FragmentManager manager) {
        super(manager);
    }

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

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

    public void addFrag(Fragment fragment, String title) {
        mFragmentList.add(fragment);
        mFragmentTitleList.add(title);
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return mFragmentTitleList.get(position);
    }
}

Tab Fragment

public class TabFragment extends ListFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.activty_listview,container, false);
    listView = (ListView) rootView.findViewById(android.R.id.list);
    return rootView;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

}

}

假设我的标签名称是“Tab1，Tab2，Tab3” 如果我上面的话，如何根据数组动态添加标签，以及如何选项卡片段知道选择了哪个标签。

欢迎任何建议。

提前致谢：）

Answer 1

 mTabLayout = (TabLayout)rootView.findViewById(R.id.tab_layout);
        mTabLayout.addTab(mTabLayout.newTab().setText(getResources().getString(R.string.tab1)));
        mTabLayout.addTab(mTabLayout.newTab().setText(getResources().getString(R.string.tab2)));
        mTabLayout.addTab(mTabLayout.newTab().setText(getResources().getString(R.string.tab3)));
        mTabLayout.addTab(mTabLayout.newTab().setText(getResources().getString(R.string.tab4)));
        mTabLayout.addTab(mTabLayout.newTab().setText(getResources().getString(R.string.tab5)));
        mTabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
        mTabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);

        mViewPager = (ViewPager)rootView.findViewById(R.id.pager);

        mPagerAdapter = new PagerAdapter
                (getActivity().getSupportFragmentManager(), mTabLayout.getTabCount());

        mViewPager.setAdapter(mPagerAdapter);
        mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(mTabLayout));
