TabLayout加载多个Fragment

首先我先说一下这个布局就是TabLayout加ViewPager然后我们TabLayout的第一个是 Fragment跟其余7个Fragment

加载的数据不一样，看代码把，代码有注释。

public class FragmentHd extends Fragment{

public TabLayout hd_tl;
public ViewPager hd_vp;
List<String> listStr; //用于存放添加Fragment的结合
List<Fragment> listTv;//用于存放Fragment的集合
public TextView quanguo;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = View.inflate(getActivity(), R.layout.fragm_hd,null);
//找控件
hd_tl = view.findViewById(R.id.hd_tl);
hd_vp = view.findViewById(R.id.hd_vp);
quanguo = view.findViewById(R.id.quanguo);
//TabLayout的横向布局 添加数据
listStr = new ArrayList();
listStr.add("全部");
listStr.add("综艺娱乐");
listStr.add("财经访谈");
listStr.add("文化旅游");
listStr.add("时尚体育");
listStr.add("青少科技");
listStr.add("养生保健");
listStr.add("公益");
listTv = new ArrayList<>();
//第一个Fragment界面
listTv.add(new FragmentQuan());
listStr.get(0);
//剩下的7个Fragment
for (int i = 0; i < 7; i++) {
listTv.add(new Fragments(listStr.get(i)));
}
//拿到适配器
MyPagerAdapter adapter = new MyPagerAdapter(getChildFragmentManager());
hd_vp.setAdapter(adapter);
//ViewpAge的预加载解决方法
hd_vp.setOffscreenPageLimit(listTv.size());
//TabLayout和ViewPage进行联动
hd_tl.setupWithViewPager(hd_vp);
return view;
}

//ViewPage的适配器
class MyPagerAdapter extends FragmentPagerAdapter {

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

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

@Override
public int getCount() {
return listTv.size();
}
@Override
public CharSequence getPageTitle(int position) {
return listStr.get(position);
}
}
}
