Can I Make tabs transparent

Question

Hi,

I have four tabs in my main screen of my app using tabhost which contains four listviews. Is it possible to make these tabs transparent so I can use a background image for the tabs to sit on top. If so how would I go about it, and canm it be done with the code I have.

public class Tabs extends TabActivity {

@Override

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    Resources res = getResources(); // Resource object to get Draw
    TabHost tabHost = getTabHost();  // The activity TabHost
    TabHost.TabSpec spec;  // Reusable TabSpec for each tab
    Intent intent;  // Reusable Intent for each tab


    intent = new Intent().setClass(this, premo.class);


    spec = tabHost.newTabSpec("Prem").setIndicator("Premo",
                      res.getDrawable(R.drawable.icontabs))
                  .setContent(intent);
    tabHost.addTab(spec);

    intent = new Intent().setClass(this, champ.class);

    // Initialise a TabSpec for each tab and add it to the TabHost
    spec = tabHost.newTabSpec("Cham").setIndicator("Cham",
                      res.getDrawable(R.drawable.cham))
                  .setContent(intent);
    tabHost.addTab(spec);


    intent = new Intent().setClass(this, 1.class);
    spec = tabHost.newTabSpec("League 1").setIndicator("L",
                      res.getDrawable(R.drawable.l1))
                  .setContent(intent);
    tabHost.addTab(spec);

    intent = new Intent().setClass(this, 2.class);
    spec = tabHost.newTabSpec("l2").setIndicator("2",
                      res.getDrawable(R.drawable.l2))
                  .setContent(intent);
    tabHost.addTab(spec);

    tabHost.setCurrentTab(0);
}

}
