        // Do the same for the other tabs
        intent = new Intent().setClass(this, search.class);

Launcher.xml

   <?xml version="1.0" encoding="utf-8"?>

       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       android:padding="5dp">
        <TabWidget

           android:layout_height="wrap_content"/>
        <FrameLayout

           android:layout_width="fill_parent"
           android:layout_height="fill_parent"

If you mean to change background color of tabs,then here is the code:

for(int i=0;i<tabhost.getTabWidget().getChildCount();i++)
{   
      tabhost.getTabWidget().getChildAt(i).setBackgroundColor(Color.WHITE); //unselected tab
}

for selected tab,

tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.GRAY); // selected tab

You can put above lines into a method (say setTabColors()) and call it:

tabHost.setOnTabChangedListener(new OnTabChangeListener() {

        @Override
        public void onTabChanged(String arg0) {

               setTabColors(tabHost);
        }
});
