Question

我有一个recyclerView，并使用editText在recyclerview中搜索项目。我已经单击Click侦听器来获取每当单击某项时的位置。单击项目而不进行搜索时，它的工作原理非常好。但是，每当我从编辑文本中搜索并单击某个项目时，它都会为我提供该项目的错误位置。

另一个问题是，一旦从recyclerview中单击该项目，我就有了关闭片段的功能，但是该功能还是不起作用。：（

recyclerView的代码

    editText = rootView.findViewById(R.id.team_select_search);

    recyclerView = rootView.findViewById(R.id.team_select_recyclerView);
    recyclerView.setHasFixedSize(true);

    recyclerView.setLayoutManager(new LinearLayoutManager(this.getContext()));

    list_items = new ArrayList<>();
    teamSelectAdapter = new TeamSelectAdapter(list_items, getContext());

    recyclerView.setAdapter(teamSelectAdapter);

    loadRecyclerViewData();

    editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {
            filter(s.toString());
        }
    });

    teamSelectAdapter.setOnItemClickListener(new TeamSelectAdapter.ClickListener() {
        @Override
        public void onItemClick(int position, View v) {
            TeamSelectModelClass clickeditem = list_items.get(position);

            String team_id = clickeditem.getTeam_id();
            String team_name = clickeditem.getTeam_name();
            String team_logo_url = clickeditem.getTeam_logo_url();

            Toast.makeText(getContext(),team_name,Toast.LENGTH_SHORT).show();

            close_frag();
        }
    });

    return rootView;
}

private void close_frag(){

        getChildFragmentManager().beginTransaction().detach(this).commit();

}

private void filter(String text){
    ArrayList<TeamSelectModelClass> filteredList = new ArrayList<>();

    for (TeamSelectModelClass item : list_items){
        if(item.getTeam_name().toLowerCase().contains(text.toLowerCase())){
            filteredList.add(item);
        }
    }
    teamSelectAdapter.filterList(filteredList);
}

recyclerview适配器的代码：

public class TeamSelectAdapter extends RecyclerView.Adapter<TeamSelectAdapter.ViewHolder> {

private List<TeamSelectModelClass> list_items;
private Context context;

private static ClickListener clickListener;

public interface ClickListener {
    void onItemClick(int position, View v);
}

public void setOnItemClickListener(ClickListener clickListener) {
    TeamSelectAdapter.clickListener = clickListener;
}

public void filterList(ArrayList<TeamSelectModelClass> filteredList){
    list_items = filteredList;
    notifyDataSetChanged();
}

public TeamSelectAdapter(List<TeamSelectModelClass> list_items, Context context) {
    this.context=context;
    this.list_items=list_items;

}

@NonNull
@Override
public TeamSelectAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
    final View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.team_select_card_layout,viewGroup,false);

    final ViewHolder viewHolder = new ViewHolder(view);



    return viewHolder;
}

@Override
public void onBindViewHolder(@NonNull TeamSelectAdapter.ViewHolder viewHolder, int i) {
    TeamSelectModelClass teamSelectModelClass = list_items.get(i);

    viewHolder.textView_team_id.setText(teamSelectModelClass.getTeam_id());
    viewHolder.textView_team_name.setText(teamSelectModelClass.getTeam_name());
    if(teamSelectModelClass.getTeam_logo_url()!=null){
        Picasso.get().load(teamSelectModelClass.getTeam_logo_url()).into(viewHolder.imageView_team_logo);
    }else {
        Picasso.get().load(R.drawable.psa_logo).into(viewHolder.imageView_team_logo);
    }

}

public void clear(){
    list_items.clear();
    notifyDataSetChanged();
}



@Override
public int getItemCount() {
    return list_items.size();
}

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

    RelativeLayout relativeLayout_team_select_card_layout;
    TextView textView_team_id;
    TextView textView_team_name;
    ImageView imageView_team_logo;

    public ViewHolder(@NonNull View itemView) {
        super(itemView);

        itemView.setOnClickListener(this);
        relativeLayout_team_select_card_layout = itemView.findViewById(R.id.team_select_card_layout);
        textView_team_id = itemView.findViewById(R.id.team_select_team_id);
        textView_team_name = itemView.findViewById(R.id.team_select_team_name);
        imageView_team_logo = itemView.findViewById(R.id.team_select_team_logo);

    }

    @Override
    public void onClick(View v) {
        clickListener.onItemClick(getLayoutPosition(), v);
    }
}
}

Answer 1

尝试一下........

尝试在搜索时获取商品名称，然后从完整列表中进行检查，例如

Arraylist<String> names    //total names of items.
String serchItem           //name of item from search.

然后，....

if(names.contains(searchItem)){
    int position=names.indexOf(searchItem);
 }

如果您找到其他方法，请让我知道......谢谢

Answer 2

private void filter(String text){
    ArrayList<TeamSelectModelClass> filteredList = new ArrayList<>();

    for (TeamSelectModelClass item : list_items){
        if(item.getTeam_name().toLowerCase().contains(text.toLowerCase())){
            filteredList.add(item);
        }
    }
    teamSelectAdapter.filterList(filteredList);
    list_items.clear();
    list_items.addAll(filteredList);
}

在您的活动中尝试这个。您正在尝试根据旧的 list_items 列表敬酒物品。
