关于android:Android笔记ViewPager嵌套fragment

ViewPager嵌套Fragment

新建4个Fragment；

新建ViewPagerAdapter继承FragmentPagerAdapter;

public class ViewpagerAdapter extends FragmentPagerAdapter {    private ArrayList<Fragment> arrayList;    public ViewpagerAdapter(@NonNull FragmentManager fm,ArrayList<Fragment> arrayList) {        super(fm);        this.arrayList=arrayList;    }    @NonNull    @Override    public Fragment getItem(int position) {        return arrayList.get(position);    }    @Override    public int getCount() {        return arrayList.size();    }}

在MainActivity中为ViewPager绑定适配器；

   arrayList=new ArrayList<>();       arrayList.add(new Fragment1());       arrayList.add(new Fragment2());       arrayList.add(new Fragment3());       arrayList.add(new Fragment4());       viewpagerAdapter= new ViewpagerAdapter(getSupportFragmentManager(),arrayList);       viewpager.setAdapter(viewpagerAdapter);
