Android:我如何进行一次升级调用，让它显示在不同的选项卡上，tablayout？

<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabMode="fixed"
    app:tabGravity="fill"/>

<android.support.v4.view.ViewPager
    android:id="@+id/view_pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

TabLayout tabLayout = findViewById(R.id.tab_layout);
ViewPager viewPager = findViewById(R.id.view_pager);

// 创建适配器
PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager());

// 添加选项卡和对应的Fragment
adapter.addFragment(new UpgradeFragment(), "升级");
adapter.addFragment(new CallFragment(), "调用");

// 设置适配器
viewPager.setAdapter(adapter);
tabLayout.setupWithViewPager(viewPager);

public class PagerAdapter extends FragmentPagerAdapter {
    private List<Fragment> fragments = new ArrayList<>();
    private List<String> titles = new ArrayList<>();

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

    public void addFragment(Fragment fragment, String title) {
        fragments.add(fragment);
        titles.add(title);
    }

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

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

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

public class UpgradeFragment extends Fragment {
    // 升级的内容
}

public class CallFragment extends Fragment {
    // 调用的内容
}
