    <p>A couple possibilities come to mind. </p> <p>If you're using a TabActivity (not a requirement, but makes things easier), the tabhost must have <code>android:id="@android:id/tabhost"</code> as the id. </p> <p>I've also seen it said that the tabhost must be the root node. I cannot confirm that using the android docs. I'd probably make this change after all other avenues have failed (or someone confirms that it is true). </p> <p>If you are using a TabActivity, you don't need to reference the tabhost by id, or use the setup() method. I see you are using the setup() method, but I can;t tell if your activity is a TabActivity. If it is, maybe that's causing your issue.</p> <p>Following is the method I use for a tab layout setup and it works for me. Note that this assumes the tabhost as the root node of the layout and it has <code>android:id/tabhost</code> as the id and it is a TabActivity.</p> <p><strong>tabhost code:</strong></p> <pre><code>public class Tabs extends TabActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.your_layout); TabHost tabHost = getTabHost(); TabHost.TabSpec spec; spec = tabHost.newTabSpec("tag1").setIndicator("All").setContent(R.id.tab1); tabHost.addTab(spec); spec = tabHost.newTabSpec("tag2").setIndicator("Personal").setContent(R.id.tab2); tabHost.addTab(spec); } } </code></pre> <p>Hope this helps!

    1. COThe getTabHost() isn't a method I have defined. Do I make this method return the TabHost Id or something?

    2. COIf you are extending TabActivity it is a method from there.

    3. COPlease keep in mind that TabActivity is deprecated. I would use ActionBarSherlock http://actionbarsherlock.com/ and use only the new ActionBar APIs to create Tabs. This makes everything a lot easier especially moving to Ice Cream Sandwich, that will get a lot of new devices in the next half year...

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.
