    <p>Following question has kept me puzzled for a while and I thought maybe asking about this does no harm. I have the following layout.xml and style.xml files;</p> <p>res/layout/layout.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" &gt; &lt;LinearLayout style="@style/headerContainer" /&gt; &lt;LinearLayout style="@style/footerContainer" /&gt; &lt;ScrollView style="@style/contentContainer" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>res/values/style.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;resources&gt; &lt;style name="container"&gt; &lt;item name="android:layout_width"&gt;fill_parent&lt;/item&gt; &lt;/style&gt; &lt;style name="headerContainer" parent="container"&gt; &lt;item name="android:layout_height"&gt;40dp&lt;/item&gt; &lt;item name="android:layout_alignParentTop"&gt;true&lt;/item&gt; &lt;item name="android:background"&gt;#80FF0000&lt;/item&gt; &lt;item name="android:id"&gt;@+id/header&lt;/item&gt; &lt;/style&gt; &lt;style name="footerContainer" parent="container"&gt; &lt;item name="android:layout_height"&gt;50dp&lt;/item&gt; &lt;item name="android:layout_alignParentBottom"&gt;true&lt;/item&gt; &lt;item name="android:background"&gt;#8000FF00&lt;/item&gt; &lt;item name="android:id"&gt;@+id/footer&lt;/item&gt; &lt;/style&gt; &lt;style name="contentContainer" parent="container"&gt; &lt;item name="android:layout_height"&gt;60dp&lt;/item&gt; &lt;item name="android:layout_below"&gt;@id/header&lt;/item&gt; &lt;item name="android:layout_above"&gt;@id/footer&lt;/item&gt; &lt;item name="android:background"&gt;#800000FF&lt;/item&gt; &lt;/style&gt; &lt;/resources&gt; </code></pre> <p>Now, the question is, is there a danger of overlapping IDs as I'm introducing them in style.xml? Funny thing is that this approach works, on the emulator I'm using at least, but the created IDs are not being added to the <code>R</code> class. And I'm a bit confused how they are defined once my layout is inflated.</p>

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.
