Use the <a href="http://developer.android.com/training/improving-layouts/smooth-scrolling.html" rel="nofollow">ViewHolder</a> pattern. <a href="http://developer.android.com/training/improving-layouts/smooth-scrolling.html" rel="nofollow">http://developer.android.com/training/improving-layouts/smooth-scrolling.html</a> Hold View Objects in a View Holder Your code might call findViewById() frequently during the scrolling of ListView, which can slow down performance. Even when the Adapter returns an inflated view for recycling, you still need to look up the elements and update them. A way around repeated use of findViewById() is to use the "view holder" design pattern. <blockquote> A ViewHolder object stores each of the component views inside the tag field of the Layout, so you can immediately access them without the need to look them up repeatedly. First, you need to create a class to hold your exact set of views. For example: </blockquote> <pre><code>static class ViewHolder { TextView text; TextView timestamp; ImageView icon; ProgressBar progress; int position; } </code></pre> <blockquote> Then populate the ViewHolder and store it inside the layout. </blockquote> <pre><code>ViewHolder holder = new ViewHolder(); holder.icon = (ImageView) convertView.findViewById(R.id.listitem_image); holder.text = (TextView) convertView.findViewById(R.id.listitem_text); holder.timestamp = (TextView) convertView.findViewById(R.id.listitem_timestamp); holder.progress = (ProgressBar) convertView.findViewById(R.id.progress_spinner); convertView.setTag(holder); </code></pre> Some other examples : <a href="http://xjaphx.wordpress.com/2011/06/16/viewholder-pattern-caching-view-efficiently/" rel="nofollow">http://xjaphx.wordpress.com/2011/06/16/viewholder-pattern-caching-view-efficiently</a> <a href="http://www.jmanzano.es/blog/?p=166" rel="nofollow">http://www.jmanzano.es/blog/?p=166</a>

Guidance

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.
