Android searchView 在完全滚动之前不搜索列表

Question

我有一个带有自定义适配器的列表视图，我正在尝试将 SearchView 与 CustomFilter 一起使用。但是搜索 "fully" 无效。

当我在列表视图的可视区域搜索某些内容时，它能够搜索，并且所有非可视区域都未包含在搜索中。

这是一个关于发生了什么的视频：

主要

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_board_game_list, container, false);
        this.listView = (ListView) view.findViewById(R.id.listView);

        DatabaseAccess databaseAccess = DatabaseAccess.getInstance(this.getContext());
        databaseAccess.open();

        List<String> boardgamesNames = databaseAccess.getNames();
        List<String> urls = databaseAccess.getUrls();

        adapter = new bgAdapter(getContext(), R.layout.row_layout);
        adapterOriginal = new bgAdapter(getContext(), R.layout.row_layout);
        databaseAccess.close();
        listView.setAdapter(adapter);

        int i = 0;
        for(String name: boardgamesNames) {

            boardgameListRow data = new boardgameListRow(urls.get(i), boardgamesNames.get(i));
            i++;
            adapter.add(data);
            adapterOriginal.add(data);
        }

        listView.setDivider(null);
        listView.setDividerHeight(0);

        searchView = (SearchView)view.findViewById(R.id.searchId);
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {

                if (newText.length() > 0) {
                    adapter.getFilter().filter(newText);
                }

                return false;
            }
        });

        searchView.setOnCloseListener(new SearchView.OnCloseListener() {
            @Override
            public boolean onClose() {

                BoardGameListFragment fragment= new BoardGameListFragment();
                FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();
                fragmentTransaction.replace(R.id.fragment_container,fragment);
                fragmentTransaction.commit();
                //adapter = adapterOriginal;
                return true;
            }
        });
        // Inflate the layout for this fragment
        return view;
    }
}

这是适配器：

Answer 1

我认为你需要在 onQueryTextChange 中调用 notifyDataSetChanged()

Answer 2

我修复了它，我在 bgAdapter 中使用了错误的变量。如果可能，请删除此问题。

    ListView lstdetail;
