reusing fragments in a fragmentpageradapter
android, android-compatibility, android-fragments, fragment
Solution
The `FragmentPagerAdapter` already caches the `Fragments` for you. Each fragment is assigned a tag, and then the `FragmentPagerAdapter` tries to call `findFragmentByTag`. It only calls `getItem` if the result from `findFragmentByTag` is `null`. So you shouldn't have to cache the fragments yourself.
Problem
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)); } } ```
