listviewonClickは間違った結果を返します

SQLiteデータベースのデータを使用したカスタムリストビューがあります。アイテムの追加と編集ができます。また、ツールバーにSearchVIewがあり、名前でアイテムを検索できます。

問題は、アイテムを編集し、SearchViewを使用してそれを見つけたいときに、onClickメソッドが間違ったID（リストの最初のアイテム）を返すことです。検索を使用しない場合は、すべて問題ありません。例えば：

私のクラスコード：

public class ProductCategoryActivity extends AppCompatActivity {

private ListView myProductsList;
private DataBaseHelper dataBaseHelper;
private SQLiteDatabase db;
private Cursor productCursor;
private ArrayList<Product> productList;
private int tableId;
private String dbName;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my_products);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    Intent idOfGroup = new Intent(getIntent());
    tableId = idOfGroup.getIntExtra("table_id", 0);

    myProductsList = (ListView) findViewById(R.id.lvMyProducts);

    switch (tableId) {
        case 1:
            dbName = DataBaseHelper.TABLE_MY_PRODUCTS;
            break;
    }

    //allow adding and editing products if tableId == 1
    if (tableId == 1) {
        myProductsList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                //get id by click on list view item
                String sql = "SELECT " + DataBaseHelper.COLUMN_ID + "  FROM " + dbName;
                productCursor = db.rawQuery(sql, null);
                ArrayList<Long> arrayList = new ArrayList<>();
                if (productCursor.moveToFirst()) {
                    do {
                        arrayList.add(Long.parseLong(productCursor.getString(0)));
                    } while (productCursor.moveToNext());
                } else {
                    throw new NullPointerException();
                }
                //sending id to another activity
                Intent intent = new Intent(ProductCategoryActivity.this, ProductAddEditActivity.class);
                intent.putExtra("id", arrayList.get(position));
                startActivity(intent);
            }
        });
    }
    dataBaseHelper = new DataBaseHelper(getApplicationContext());
    //creating db
    dataBaseHelper.create_db();

}

@Override

    switch (item.getItemId()) {
        case R.id.newProduct:

            startActivity(intent);
            return true;
