    1. COWouldn't this remove all the benefits of using a `ViewHolder` in the first place though?

    2. COJust to complete my previous comment; the documentation encourages the `null` check. Have a look at the documentation of the `getView()`method.

    3. COYes, it will remove all benefits of ViewHolder. However I have also faced lot of problems with Listview though strange one. This approach solved my problem. Only use this approach if your list is small for large list items this is not recomended.

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.
