Question

我正在尝试为我的2个数组列表创建过滤器。在下面将所有内容汇总在一起会更容易：

这是我的数组列表的样子：

[1] Names:

1: McDonals
2: KFC
3: H&M
4: Harrods
5: Test
etc...

和另一个数组列表：

[2] Icons: 

1: url1
2: url2
3: url3
4: url4
5: url5

我将这两个列表都放在oder的recyclerview中（在Android Studio中），以显示具有名称的[1] arraylist的第一个位置和带有图标的[2] arraylist的第一个位置，看起来像：

[1]: Name: McDonals, Icon: url1
[2]: Name: KFC, Icon: url2
[3]: Name: H&M, Icon: url3
[4]: Name: Harrods, Icon: url4
[5]: Name: Test, Icon: url5

知道什么是问题... 我正在尝试使用名称从[1] arraylist创建字符串过滤器

目前我有类似的东西，它工作得很好，但现在足够了：D

@Override
    public boolean onQueryTextChange(String s) {
    PartnersModel partnersModel = new PartnersModel();
    if (s == null || s.trim().isEmpty()) {
        initRecyclerView();
    }
    filteredValues = new ArrayList<String>(partnersModel.getmPartners_Name());
    for (String value : partnersModel.getmPartners_Name()) {
        if (!value.toLowerCase().contains(s.toLowerCase())) {
            filteredValues.remove(value);
        }
        initRecyclerView(filteredValues);
    }
    return false;
}

例如，当我在编辑文本“ Harr”中放入它时，它会从arraylist中删除所有字符串，这些字符串的标题中没有它，但是我仍然带有图标的arraylist。键入“ Harr”会删除“ McDonals”，“ KFC”，“ H＆M”，“ Test”，但是我仍然有5个位置的arraylist，并且自动在我的基本arraylist中的位置“ 4”的我的“ Harr”自动获取图标从带有图标的arraylist中的第一个位置开始，它看起来像：

[1]: Name: Harrods, Icon: url1

我希望它看起来像这样

[1]: Name: Harrods, Icon: url4

这是我的代码：

private void initRecyclerView() {
    PartnersModel partnersModel = new PartnersModel();
    adapter_partnerzy = new RecyclerViewAdapter_partners(getContext(), partnersModel.mPartners_Id, partnersModel.mPartners_Wid, partnersModel.mPartners_Name, partnersModel.mPartners_Longitude, partnersModel.mPartners_Latitude, partnersModel.mPartners_Desc, partnersModel.mPartners_Picture, partnersModel.mPartners_City, partnersModel.mPartners_Multiplier, partnersModel.mPartners_OwnedPoints);
    recyclerView.setAdapter(adapter_partnerzy);
    recyclerView.setHasFixedSize(true);
    recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
}

private void initRecyclerView(ArrayList<String> filteredName) {
    PartnersModel partnersModel = new PartnersModel();
    adapter_partnerzy = new RecyclerViewAdapter_partners(getContext(), partnersModel.mPartners_Id, partnersModel.mPartners_Wid, filteredName, partnersModel.mPartners_Longitude, partnersModel.mPartners_Latitude, partnersModel.mPartners_Desc, partnersModel.mPartners_Picture, partnersModel.mPartners_City, partnersModel.mPartners_Multiplier, partnersModel.mPartners_OwnedPoints);
    recyclerView.setAdapter(adapter_partnerzy);
    recyclerView.setHasFixedSize(true);
    recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
}

和适配器：

public class ViewHolder extends RecyclerView.ViewHolder implements SearchView.OnQueryTextListener{
    ImageView image;
    TextView imageName, textViewPokazNagrody, textViewSchowajNagrody, textView_ownedPoints, opisPromocji, textViewDistanceFromPartner;
    RelativeLayout kafelekPartneraLayoutNagrod, layoutSchowajNagrody, layoutPokazNagrody, relativeLayoutPartnera;
    LinearLayout wariantNagrody;

    public ViewHolder(View itemView) {
        super(itemView);
        layoutSchowajNagrody = itemView.findViewById(R.id.layout_tekstu_schowaj_nagrode);
        layoutPokazNagrody = itemView.findViewById(R.id.layout_tekstu_pokaz_nagrode);
        relativeLayoutPartnera = itemView.findViewById(R.id.relativeLayoutPartnera);
        wariantNagrody = itemView.findViewById(R.id.wariantNagrody);
        textView_ownedPoints = itemView.findViewById(R.id.textView_layoutPartner_ownedPoints);
        opisPromocji = itemView.findViewById(R.id.opisPromcji);
        image = itemView.findViewById(R.id.zdjecie);
        imageName = itemView.findViewById(R.id.zdjecieTextView);
        textViewPokazNagrody = itemView.findViewById(R.id.textViewPokazNagrody);
        textViewSchowajNagrody = itemView.findViewById(R.id.textViewSchowajNagrody);
        kafelekPartneraLayoutNagrod = itemView.findViewById(R.id.kafelekPartneraLayoutNagrod);
        textViewDistanceFromPartner = itemView.findViewById(R.id.textView_partnerLayout_distanceFromPartner);
    }

    @Override
    public boolean onQueryTextSubmit(String s) {
        return false;
    }

    @Override
    public boolean onQueryTextChange(String s) {
        return false;
    }
}

public RecyclerViewAdapter_partners(Context mContext, ArrayList<String> mPartners_Id, ArrayList<String> mPartners_Wid, ArrayList<String> mPartners_Name, ArrayList<String> mPartners_Longitude, ArrayList<String> mPartners_Latitude, ArrayList<String> mPartners_Desc, ArrayList<String> mPartners_Picture, ArrayList<String> mPartners_City, ArrayList<String> mPartners_Multiplier, ArrayList<String> mPartners_OwnedPoints ) {

            holder.textViewPokazNagrody.setOnClickListener(new View.OnClickListener() {

            Location partnerLocation = new Location("partner");
            partnerLocation.setLatitude(Double.parseDouble(mLatitude.get(position)));

            float distanceInKilometers = mineLocation.distanceTo(partnerLocation)/1000;

            holder.textViewDistanceFromPartner.setText(String.valueOf(f.format(distanceInKilometers)) + " km");

            holder.textViewSchowajNagrody.setOnClickListener(new View.OnClickListener() {
                @Override

        } else {
            Log.v("sorting", "Ilosc punktow w pozycji: " + position + " < 0");
        }
    }
}

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

有什么主意吗？非常感谢：）

如何在onQueryTextChange中修改两个arraylist？
