    <p>In my <code>Android Application</code> whose server side App is also getting developed by me. In this app android app request some <code>XML</code> from server and parse it. The <code>XML</code> contains the information that describes how much tab should be in the app and each tab have a <code>ListView</code> while each list item can navigate to another <code>Activity</code> which may also result in another sub <code>ListView</code> this level is infinite. <code>XML</code> that I am generating from server is of this type.</p> <pre><code>&lt;Application&gt; &lt;Tabs&gt; &lt;Tab id="1" tabtitle="Info"&gt; &lt;ListItems&gt; &lt;ListItem id="1" itemtype="list" itemtitle="1.1" itemdata="Issue1,Issue2,Issue3,Issue4,Issue 5"&gt; &lt;/ListItem&gt; &lt;ListItem id="3" itemtype="list" itemtitle="1.2" itemdata="News Links"&gt; &lt;/ListItem&gt; &lt;ListItem id="5" itemtype="list" itemtitle="1.3" itemdata="sampleDataURL type"&gt; &lt;ListItems&gt; &lt;ListItem id="1" itemtype="list" itemtitle="1.3.1" itemdata="some data"&gt; &lt;/ListItem&gt; &lt;ListItem id="3" itemtype="list" itemtitle="1.3.2" itemdata="some data"&gt; &lt;ListItems&gt; &lt;ListItem id="1" itemtype="list" itemtitle="1.3.2.1" itemdata="Issue1,Issue2,Issue3,Issue4,Issue 5"&gt; &lt;/ListItem&gt; &lt;ListItem id="3" itemtype="list" itemtitle="1.3.2.2" itemdata="News Links"&gt; &lt;/ListItem&gt; &lt;/ListItems&gt; &lt;/ListItem&gt; &lt;/ListItems&gt; &lt;/ListItem&gt; &lt;/ListItems&gt; &lt;/Tab&gt; &lt;Tab id="2" tabtitle="More"&gt; &lt;ListItems&gt; &lt;/ListItems&gt; &lt;/Tab&gt; &lt;Tab id="3" tabtitle="Share"&gt; &lt;ListItems&gt; &lt;/ListItems&gt; &lt;/Tab&gt; &lt;/Tabs&gt; &lt;/Application&gt; </code></pre> <p>As a result my my android can generate 3 tabs at runtime but please guide what type of code/logic should I compose to write it's <code>SAXParser</code> and what type of Model data should i populate in android App through parser.Should i go for <code>HashMap</code> rather than <code>ArrayList&lt;CustomClass&gt;</code>. </p> <p>This is challenging for me to implement it efficiently and robustly.</p>

    2. COhey man list will never go beyond 4-5 level practically , but at the time of writing the code we cannot know how longer the list may be

    3. COYou can use "ViewAnimator + tab view" to control your tab based design. this way, you will have to create 3 different activities which will work as the content of 3 tabs. In each activity, use ViewAnimator as outermost layout and add listviews to it as per your requirement. For data structure, you can use either of hashmap OR arrayList.. but in the end it finally depends on how efficiently you use them. may be this helps..

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.
