    1. CO`Listview duplicates item every 6 times` - What does this mean? In the `for-loop` inside your `onCreateView()`, change `price=0;` to `price=i;`. Do the items still duplicate?

    2. COSeems like there is stuff missing from your code that makes it hard to diagnose the issue. From what you have included, there is nothing blatantly obvious. I would try changing `ListViewItem item = items.get(position);` to `ListViewItem item = getItem(position)` assuming that you mistakenly put `CustomListView.java` instead of `CustomListViewAdapter.java`

    3. COAnd why is the layout `android.R.layout.simple_list_item_1` in your adapter's constructor? You are inflating, changing, and returning a custom one in your getView().

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
