獲取item on setOnItemClickListener listview通過編號

Question

我怎麼能得到項目的詳細信息點擊listview按id，而不是位置。我的代碼是：

listViewCatalog.setOnItemClickListener(new AdapterView.OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, 
           long id) { 
      //Category category = categoryAdapter.getItem(position); 

      Intent productDetailsIntent = new Intent(getBaseContext(), ProductDetailsActivity.class); 
      productDetailsIntent.putExtra(ShoppingCartHelper.PRODUCT_INDEX, position); 
      startActivity(productDetailsIntent); 
     } 
    }); 

代碼的工作，我可以在其他類（ShoppingCartHelper.java）查看詳細我的產品。但是我想在該產品上使用id獲取詳細信息產品。任何建議傢伙？

得到Category id像

listViewCatalog.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 

@Override 
public void onItemClick(AdapterView<?> parent, View view, int position,long id) { 

Category item=(Category)parent.getItemAtPosition(position); 

int categoryId=item.getCategoryId(); // get Category Id 

    } 
});
