java - 退出android中的活动后重新加载片段

Question

我一直在开发一个应用程序，其中我有一个与活动通信的片段。在该通信中，我已经应用了共享元素转换，到目前为止它可以工作，但是当我退出活动并在两秒钟后返回片段时出现问题，片段开始重新加载我尝试搜索可能的解决方案但找不到原因所以我希望有人可以在这里帮助我。

更新：因为我已经为动画使用了共享元素过渡，并且我注意到没有后按时的过渡，片段不会重新创建并且它工作正常但是使用动画它会在几秒钟后再次重新创建。 这是我的片段代码

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        view = inflater.inflate(R.layout.fragment_feed, container, false);
        getActivity().getWindow().setExitTransition(null);
        setRetainInstance(true);
        toolbar = (Toolbar)view.findViewById(R.id.toolbar);
        // ((MainActivity)getActivity()).setSupportActionBar(toolbar);
        feed_recycler_view = (RecyclerView)view.findViewById(R.id.feed_recycler_view);
        //ViewCompat.setNestedScrollingEnabled(feed_recycler_view, false  );
        CustomTextView customTextView = (CustomTextView)toolbar.findViewById(R.id.toolbar_title);


        feed_layout_manager = new LinearLayoutManager(getActivity(),LinearLayoutManager.VERTICAL,false);
        feed_recycler_view.setLayoutManager(feed_layout_manager);
        //feed_recycler_view.setNestedScrollingEnabled(false);
        feed_recycler_view.setHasFixedSize(true);
        feed_adapter = new FeedAdapter(FeedUtils.generateFeeds(getContext()),this);
        feed_recycler_view.setAdapter(feed_adapter);
        return view;
    }

    public static FeedFragment newInstance() {
        FeedFragment fragment = new FeedFragment();
        return fragment;
    }

    public static void applyFont(CustomTextView tv, Activity context) {
        tv.setTypeface(Typeface.createFromAsset(context.getAssets(), "fonts/Quicksand-Medium.ttf"));
    }
    @Override
    public boolean onBackPressed() {
        return false;
    }

    @Override
    public void onFeedItemClick(int pos, Feed_Data_Provider feedDataProvider, AppCompatImageView shareImageView) {
        Intent intent = new Intent(getContext(), ChatActivity.class);
        intent.putExtra(EXTRA_FEED_ITEM, feedDataProvider);
        intent.putExtra(EXTRA_FEED_IMAGE_TRANSITION_NAME, ViewCompat.getTransitionName(shareImageView));

        ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(
                getActivity(),
                shareImageView,
                ViewCompat.getTransitionName(shareImageView));

        startActivity(intent, options.toBundle());
    }
}

这是活动课

public class ChatActivity extends AppCompatActivity {
        AppCompatImageView chat_image;
    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_chat);
        getWindow().setEnterTransition(null);
        Bundle extras = getIntent().getExtras();
        Feed_Data_Provider feedItem = extras.getParcelable(FeedFragment.EXTRA_FEED_ITEM);
        chat_image = (AppCompatImageView)findViewById(R.id.chat_image);
        postponeEnterTransition();
        int imageUrl =feedItem.getClub_image();
        supportPostponeEnterTransition();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            String imageTransitionName = extras.getString(FeedFragment.EXTRA_FEED_IMAGE_TRANSITION_NAME);
            if (imageTransitionName != null) {
                chat_image.setTransitionName(imageTransitionName);
            }
        }
        Glide.with(this)
                .load(imageUrl)
                .listener(new RequestListener<Drawable>() {
                    @Override
                    public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
                        supportStartPostponedEnterTransition();
                        return false;

                    }

                    @Override
                    public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
                        supportStartPostponedEnterTransition();
                        return false;
                    }
                })
                .into(chat_image);

    }


}
