Tab host autoscroll – Programmatically - android-tabhost

Question

I want to develop an application simulating the tab browsing like Dolphin HD. Below is the XML file I have used to create the UI.
My queries are,
I am not able to get the fixed size tab like dolphin HD.
When I have created around 4-5 tabs, now I want to programmatically set the focus to new tab and scroll it to the current view.
Similar query was posted in the below link, but its not working still…
Android - Programmatic scrolling of TabWidget
In add new tab method, I tried inserting the below lines as mentioned in the above link…. but it didn’t work…
tabHost.setFocusableInTouchMode(true);
tabHost.setCurrentTab(z);
tabHost.setFocusable(true);
//Vinod
for ( i = 0; i < z; i++) {
getTabWidget().getChildAt(i).setFocusableInTouchMode(true);
}

The delay was due to timing, so just a delay would work perfectly alright.
HorizontalScrollView hv = (HorizontalScrollView)findViewById(id.tab1);
//hv.fullScroll(HorizontalScrollView.FOCUS_RIGHT);
for ( i = 0; i < z; i++) {
getTabWidget().getChildAt(i).setFocusableInTouchMode(true);
}
hv.postDelayed(new Runnable() {
public void run()
{
HorizontalScrollView hv = (HorizontalScrollView)findViewById(id.tab1);
hv.fullScroll(HorizontalScrollView.FOCUS_RIGHT);
}
}, 100L);
