    <p>I'm trying to implement the ViewHolder pattern with convertView. Two questions:</p> <p>1) When I comment lines #1 and #2 (which are required for the pattern) everything works fine. When the if is in place everything gets scrambled, the first element of the list gets shown twice (in the beginning and in the end of the list) and after some orientation changes and list scrolling everything gets jumbled. Why is this happenning?</p> <p>2) I'm using a ListActivity and providing the TextView and array of Strings for the ArrayAdapter (#3) but for some reason I still need line (#4) otherwise the list items are blank. Is this because i'm not using super.getView()?</p> <pre><code>class SushiAdapter extends ArrayAdapter&lt;String&gt; { private final Activity context; SushiAdapter(Activity context) { super(context, R.layout.row, R.id.label, MenuItems); // #3 this.context = context; } public View getView(int position, View convertView, ViewGroup parent) { View row = convertView; if (row == null) { //#1 LayoutInflater inflater = context.getLayoutInflater(); row = inflater.inflate(R.layout.row, parent, false); ViewHolder holder = new ViewHolder(); holder.icon = (ImageView) row.findViewById(R.id.icon); holder.position = position; holder.item = (TextView) row.findViewById(R.id.label); row.setTag(holder); } // #2 ViewHolder newHolder = (ViewHolder) row.getTag(); newHolder.item.setText(MenuItems[newHolder.position]); // #4 newHolder.icon.setImageResource(R.drawable.sushi); return row; } } </code></pre>

    1. COI think I've figured out the answer to 1) it's because I'm saving position to the ViewHolder, which is something I probably shouldn't do.

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.
