Code example for TabHost

Methods: getCurrentTab

            return Fragment.instantiate(mContext, info.clss.getName(), info.args);
        public void onTabChanged(String tabId) {
            int position = mTabHost.getCurrentTab();
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        public void onPageSelected(int position) {
            // Unfortunately when TabHost changes the current tab, it kindly 
            // also takes care of putting focus on it when not in touch mode. 
            // The jerk. 
            // This hack tries to prevent this from pulling focus out of our 
            // ViewPager.
