Description

private void initAdapter() {
linearLayoutManager = new LinearLayoutManager(getAttachActivity());
linearLayoutManager.setStackFromEnd(false);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.addItemDecoration(new VerticalItemDecoration(getResources().getDimensionPixelSize(R.dimen.dp_2), getColor(R.color.common_line_color)));
mDiscoverAdapter = new DiscoverAdapter();

    helper = new QuickAdapterHelper.Builder(mDiscoverAdapter)
            .setTrailingLoadStateAdapter(new TrailingLoadStateAdapter.OnTrailingListener() {
                @Override
                public void onLoad() {
                    request();
                }

                @Override
                public void onFailRetry() {
                    request();
                }

                @Override
                public boolean isAllowLoading() {
                    return !refreshLayout.isRefreshing();
                }
            }).build();
    recyclerView.setItemAnimator(null);
    recyclerView.setAdapter(helper.getAdapter());
}

public void onHttpSuccess(HttpData<List> result) {
if (refreshLayout.isRefreshing()) {
refreshLayout.setRefreshing(false);
}
if (result.isRequestSucceed()) {
List resultList = result.getContent();
if (resultList.isEmpty()) {
helper.setTrailingLoadState(new LoadState.NotLoading(true));
if (pageInfo.isFirstPage()) {
showEmpty();
} else {
showComplete();
}
return;
}
dynamicList.addAll(resultList);
mDiscoverAdapter.submitList(dynamicList);
helper.setTrailingLoadState(new LoadState.NotLoading(false));
showComplete();
pageInfo.nextPage();
}
}

implementation "io.github.cymchad:BaseRecyclerViewAdapterHelper4:4.1.4"

出现的问题是:
执行helper.setTrailingLoadState(new LoadState.NotLoading(false));之后会执行onLoad方法,而且会出现自动滑动到底部

Research direction

Start with the initAdapter and onHttpSuccess methods shown in the report, focusing on QuickAdapterHelper, TrailingLoadStateAdapter, and the 4.1.4 dependency. Reproduce the sequence after setTrailingLoadState(new LoadState.NotLoading(false)) and trace why onLoad runs and the RecyclerView scrolls to the bottom. Done means the state update no longer triggers unintended loading or automatic scrolling.
