Hi guys. Can someone please tell me how to change tab by clicking on element INSIDE the tab? I already tried it with global data. The code looks like this:

public class Tabs extends TabActivity {

int tabNumber = 0;
private TabHost tabHost;
int returnedTabNumber = 0;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


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

    // Create an Intent to launch an Activity for the tab (to be reused)
    intent = new Intent().setClass(this, Tribocracy.class);

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

    // Do the same for the other tabs
    intent = new Intent().setClass(this, Areas.class);
    spec = tabHost.newTabSpec("areas").setIndicator("Areas",
                      res.getDrawable(R.drawable.ic_tab_albums))
                  .setContent(intent);
    tabHost.addTab(spec);

    // Do the same for the other tabs
    intent = new Intent().setClass(this, Settings.class);
    spec = tabHost.newTabSpec("settings").setIndicator("Settings",
                      res.getDrawable(R.drawable.ic_tab_albums))
                  .setContent(intent);
    tabHost.addTab(spec);

    tabHost.setCurrentTab(tabNumber);


}

protected void onResume() {
    super.onResume();


            GlobalData globalData = ((GlobalData)getApplicationContext());
            returnedTabNumber = globalData.getTabNumber();
            tabHost.setCurrentTab(returnedTabNumber);   


}

}

The global adapter looks like this:

public class GlobalData extends Application {
//----------------------------------------------------
      private int Point1;   //define the vars here
      private int Point2;   //define the vars here
      private int Point3;   //define the vars here
      private int Point4;   //define the vars here
      private int Point5;   //define the vars here
      private int Point6;   //define the vars here
      private int tabNumber;

      public int getTabNumber() //getter of the value
      {     
        return tabNumber;
      }

      public int setTabNumber(int number)     //setter of the value
      {
        tabNumber = number;
        return tabNumber;
      }

}

Now when I'm trying to change tab in my ListActivity tab by clicking on one of the items it doesn't do anything and stays on the ListActivity tab. Perhaps I shouldn't use onResume() here. Basically I want to go to first tab when I click on one of the items in the list. Please help!
