To add multiple tabs you have to create tabSpec objects than add each tabspec using .addTab() method of TabbHost.

Example

myTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
myTabHost.setup(this,getsupportFragmentManager(),android.R.id.tabcontent);
myTabHost.addTab(myTabHost.newTabSpec("tab1").setIndicator("Tab1",null), SomeFragmentClass.class,null);

myTabHost.addTab(myTabHost.newTabSpec("tab2").setIndicator("Tab2",null), AnotherFragmentClass.class,null); // just pass fragment classes with it

I hop it will help...

You don't need that second TabWidget in there.

If you're asking about adding more than 1 tab to a TabHost see this tutorial: http://developer.android.com/resources/tutorials/views/hello-tabwidget.html

Check Step 6 carefully where a newTabSpec() is created.
