    <p>I have a ListActivity displaying a bunch of objects from a list. I want to change the background &amp; text color of the row based on the state of the two booleans in the MonitorObject.</p> <p>Do I need to extend ArrayAdapter? If so, a code sample would be greatly appreciated as I have been trying to figure it out for a few days with no success. </p> <pre><code>public class Lwm extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.list); setListAdapter(new ArrayAdapter&lt;MonitorObject&gt;(this, R.layout.row, getMonitorObjects())); } private List&lt;MonitorObject&gt; getMonitorObjects() { List&lt;MonitorObject&gt; mos = new ArrayList&lt;MonitorObject&gt;(); mos.add(new MonitorObject(15000, 20000, 25000)); mos.add(new MonitorObject(15000, 14000, 18000)); mos.add(new MonitorObject(15000, 12000, 14000)); mos.add(new MonitorObject(100, 200, 250)); mos.add(new MonitorObject(3000, 2500, 3500)); return mos; } } </code></pre> <hr> <pre><code>public class MonitorObject { private int mTimeTotal; private int mWarningThreshold; private int mAlarmThreshold;`enter code here` private boolean mWarning; private boolean mAlarm; public MonitorObject(int timeTotal, int warningThreshold, int alarmThreshold) { this.mTimeTotal = timeTotal; this.mWarningThreshold = warningThreshold; this.mAlarmThreshold = alarmThreshold; mWarning = (mTimeTotal &gt; mWarningThreshold) ? true : false; mAlarm = (mTimeTotal &gt; mAlarmThreshold) ? true : false; } /*getters, setters, tostring goes here*/ } </code></pre>

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.
