Question

我的Listview可以正常工作，但是我正在使用SearchView进行搜索以在listview中查找项目。当我在列表视图中过滤没有问题，但是当我在列表视图中单击时，那会给出错误的位置。我不明白为什么这样做。你有什么想法吗？

above writed rulman is my object in my database. I searched that and I onclicked that. But my textbox readed other is my object in my database. You can look at this

ArrayList<String> StokIDFromParse;
    ArrayList<String> StokKoduFromParse;
    ArrayList<String> StokAdiFromParse;
    ArrayList<String> StokFiyatiFromParse;
    ArrayList<String> UrunArama;
    ArrayList<Boolean> KullanimYeriFromParse;
    StokDatas stokDatas;
    ArrayAdapter adapter;
final Context context = this;
EditText stokID,stokKodu,stokAdi,fiyati;
SearchView urunArama;
RadioButton petrolCihazlari,yikamaEkipmanlari;
ListView listView;
@Override

    super.onCreate(savedInstanceState);

    adapter=new ArrayAdapter(this,android.R.layout.simple_list_item_1,StokAdiFromParse);
    listView.setAdapter(stokDatas);

    VeriGetir();


urunArama.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
    @Override

        return false;
}

@Override

    if(!urunArama.toString().equals("")){
        listView.setAdapter(adapter);
        adapter.getFilter().filter(s);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

                stokAdi.setText(StokAdiFromParse.get(i));
                fiyati.setText(StokFiyatiFromParse.get(i));
                if (KullanimYeriFromParse.set(i,true)){

        listView.setAdapter(stokDatas);
        stokDatas.notifyDataSetChanged();
    }
    return false;
}
});

// ListView Onclick侦听器

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

            }

                yikamaEkipmanlari.setChecked(true);
            }
        }
    });
}

//接收数据

 public void VeriGetir(){
        ParseQuery<ParseObject> query = ParseQuery.getQuery("tableParcalar");
        query.findInBackground(new FindCallback<ParseObject>() {
            @Override
            public void done(List<ParseObject> objects, ParseException e) {
                if (e!=null){
                    Toast.makeText(getApplicationContext(),e.getLocalizedMessage(),Toast.LENGTH_LONG).show();
                }
                else {
                    if (objects.size()>0)
                    {
                        for(final ParseObject object : objects){
                            StokIDFromParse.add(object.getObjectId());
                            StokAdiFromParse.add(object.getString("StokAdi"));
                            StokKoduFromParse.add(object.getString("StokKodu"));
                            StokFiyatiFromParse.add(object.getString("Fiyati"));
                            KullanimYeriFromParse.add(object.getBoolean("KullanimAlani"));

我已经尝试过了，但是我不能帮忙我的代码吗？

This is new Screenshot on my try

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                textlenght=urunArama.toString().indexOf(textlenght);
                for (int j =0; j < StokAdiFromParse.size(); j++){
                    if (textlenght==StokAdiFromParse.get(j).length()){
                        if(urunArama.toString().equalsIgnoreCase((String)StokAdiFromParse.get(i).subSequence(0,textlenght))){
                            int z = j;
                            StokID_SUB.add(StokIDFromParse.get(j));
                            StokName_SUB.add(StokAdiFromParse.get(j));
                            StokKodu_SUB.add(StokKoduFromParse.get(j));
                            StokFiyati_SUB.add(StokFiyatiFromParse.get(j));
                            KullanimYeri_SUB.add(KullanimYeriFromParse.get(j));
                        }
                    }
                }
                stokKodu.setEnabled(false);
                stokID.setText(String.valueOf(StokID_SUB));
                stokKodu.setText(String.valueOf(StokKodu_SUB));
                stokAdi.setText(String.valueOf(StokName_SUB));
                fiyati.setText(String.valueOf(StokFiyati_SUB));

            }
        });



    }

Answer 1

我遇到了同样的问题，解决方案here很有帮助。

主要问题是点击监听器正在与原始列表进行交互，但与已过滤的列表进行交互。因此，问题在于，如果已过滤元素位于第三位置，但位于过滤列表的第一位置，则单击将与原始（未过滤）列表中第一位置的元素进行交互。

希望这种解释足以理解这个想法。
