    <p>If anyone is interested, I started playing around with creating a standard object to run on an activities UI thread. Seems to work ok. Comments welcome. I'd love this to be available on the layout designer as a component to drag onto an Activity. Can't believe something like that doesn't already exist.</p> <pre><code>package com.example.util.timer; import java.util.Timer; import java.util.TimerTask; import android.app.Activity; public class ActivityTimer { private Activity m_Activity; private boolean m_Enabled; private Timer m_Timer; private long m_Delay; private long m_Period; private ActivityTimerListener m_Listener; private ActivityTimer _self; private boolean m_FireOnce; public ActivityTimer() { m_Delay = 0; m_Period = 100; m_Listener = null; m_FireOnce = false; _self = this; } public boolean isEnabled() { return m_Enabled; } public void setEnabled(boolean enabled) { if (m_Enabled == enabled) return; // Disable any existing timer before we enable a new one Disable(); if (enabled) { Enable(); } } private void Enable() { if (m_Enabled) return; m_Enabled = true; m_Timer = new Timer(); if (m_FireOnce) { m_Timer.schedule(new TimerTask() { @Override public void run() { OnTick(); } }, m_Delay); } else { m_Timer.schedule(new TimerTask() { @Override public void run() { OnTick(); } }, m_Delay, m_Period); } } private void Disable() { if (!m_Enabled) return; m_Enabled = false; if (m_Timer == null) return; m_Timer.cancel(); m_Timer.purge(); m_Timer = null; } private void OnTick() { if (m_Activity != null &amp;&amp; m_Listener != null) { m_Activity.runOnUiThread(new Runnable() { @Override public void run() { m_Listener.OnTimerTick(m_Activity, _self); } }); } if (m_FireOnce) Disable(); } public long getDelay() { return m_Delay; } public void setDelay(long delay) { m_Delay = delay; } public long getPeriod() { return m_Period; } public void setPeriod(long period) { if (m_Period == period) return; m_Period = period; } public Activity getActivity() { return m_Activity; } public void setActivity(Activity activity) { if (m_Activity == activity) return; m_Activity = activity; } public ActivityTimerListener getActionListener() { return m_Listener; } public void setActionListener(ActivityTimerListener listener) { m_Listener = listener; } public void start() { if (m_Enabled) return; Enable(); } public boolean isFireOnlyOnce() { return m_FireOnce; } public void setFireOnlyOnce(boolean fireOnce) { m_FireOnce = fireOnce; } } </code></pre> <p>In the activity, I have this onStart:</p> <pre><code>@Override protected void onStart() { super.onStart(); m_Timer = new ActivityTimer(); m_Timer.setFireOnlyOnce(true); m_Timer.setActivity(this); m_Timer.setActionListener(this); m_Timer.setDelay(3000); m_Timer.start(); } </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
