我有一个带有自定义适配器的listview，我试图将SearchView与CustomFilter一起使用。但搜索并不完全＆＃34;工作
当我搜索列表视图的可查看区域中的某些内容时，它可以搜索，并且搜索中不包含所有不可查看的区域。
以下是有关最新情况的视频：
主
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：

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

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。
