Reading value from a field on another tab
<p>First day of Android development so forgive any ignorance.</p>

<p>My MainActivity class has the following code:</p>

<pre><code>    // Create the tabs
    intent = new Intent().setClass(this, DisplayActivity.class);
    spec = tabHost.newTabSpec("Display")
                .setIndicator("Display")
                .setContent(intent);
    tabHost.addTab(spec);

    intent = new Intent().setClass(this, SettingsActivity.class);
    spec = tabHost.newTabSpec("Settings")
                .setIndicator("Settings")
                .setContent(intent);
    tabHost.addTab(spec);
</code></pre>

<p>I want to retrieve the value of a field from settings in the display tab. How can I do this?</p>
