使用viewpager从一个片段移动到另一个片段

<androidx.viewpager.widget.ViewPager
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

public class MyPagerAdapter extends FragmentPagerAdapter {
    private List<Fragment> fragments;

    public MyPagerAdapter(FragmentManager fm, List<Fragment> fragments) {
        super(fm);
        this.fragments = fragments;
    }

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

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

ViewPager viewPager = findViewById(R.id.viewPager);
List<Fragment> fragments = new ArrayList<>();
fragments.add(new Fragment1());
fragments.add(new Fragment2());
MyPagerAdapter pagerAdapter = new MyPagerAdapter(getSupportFragmentManager(), fragments);
viewPager.setAdapter(pagerAdapter);

TabLayout tabLayout = findViewById(R.id.tabLayout);
tabLayout.setupWithViewPager(viewPager);

viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        // 页面滚动时的回调
    }

    @Override
    public void onPageSelected(int position) {
        // 页面选中时的回调
    }

    @Override
    public void onPageScrollStateChanged(int state) {
        // 页面滚动状态改变时的回调
    }
});
