在 fragmentpageradapter 中重用片段

我有一个 viewpager 可以浏览片段.我的 FragmentPagerAdapter 子类在 getItem 方法中创建了一个看起来很浪费的新片段.是否有与 listAdapter 中的 convertView 等效的 FragmentPagerAdapter 使我能够重用已创建的片段?我的代码如下.

I have a viewpager that pages through fragments. My FragmentPagerAdapter subclass creates a new fragment in the getItem method which seems wasteful. Is there a FragmentPagerAdapter equivalent to the convertView in the listAdapter that will enable me to reuse fragments that have already been created? My code is below.

public class ProfilePagerAdapter extends FragmentPagerAdapter {

    ArrayList<Profile> mProfiles = new ArrayList<Profile>();

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

    /**
     * Adding a new profile object created a new page in the pager this adapter is set to.
     * @param profile
     */
    public void addProfile(Profile profile){
        mProfiles.add(profile);
    }

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

    @Override
    public Fragment getItem(int position) {
        return new ProfileFragment(mProfiles.get(position));
    }
}
