I think this can help you:

TabHost tabHost = new TabHost(context);
tabHost.setLayoutParams(new ViewGroup.LayoutParams(YOUR_WIDTH_HERE, YOUR_HEIGHT_HERE));

You can use ViewGroup.LayoutParams.FILL_PARENT or WRAP_CONTENT or MATCH_PARENT

Then you have to change the LayoutParams class type from ViewGroup.LayoutParams to other class... if you pay attention to your classCastException, I think the error tell you what is the expected LayoutParams class.. – Cata Feb 04 '12 at 11:44
can u tell me how can i display same tabhost at bottom of the screen using java? – Navdroid Feb 04 '12 at 12:27
the best approach is to put the tab host into a RelativeLayout and then do something like this: ((RelativeLayout.LayoutParams)tabHost.getLayoutParams()).layout_alignParentBottom = true; - I didn't tried this code but it might help.. – Cata Feb 04 '12 at 12:35

For any view you can provide custom width and heiht by providing LayoutParams. All sizies in LayoutParams set in pixels. If you want to use dp - use this code:

float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 14, getResources().getDisplayMetrics());
