   private LocalActivityManager mActivityManager;

   @Override
   protected void onCreate(Bundle savedInstanceState) {

       this.history = new ArrayList<View>();
       group = this;

    history.add(v);
    setContentView(v);
}

public void back(){
    if ( history.size() > 1 ){
       history.remove(history.size() - 1);
       View v = history.get(history.size() - 1);
       setContentView(v);

 public class SalesRouteActivity extends Activity{
       @Override
       public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       // setContentView(R.layout.sales_routes);
      //getWindow().setTitle("Route");
          View viewToLoad = LayoutInflater.from(SalesActivityGroup.group).inflate(R.layout.sales_routes, null);
         this.setContentView(viewToLoad);

        //getWindow().setTitle("Route");
         SalesActivityGroup.group.setTitle("Route");
    }

}

Please advice me How can i set the Title name.

Answer 1

You can access the parent tab activity like

getParent().getParent().setTitle("New Tilte");

EXPLANATION:

Based on my understanding,
When you call the getParent the first time, you get the activity group that started the child activity.

When you call getParent the second time, you will get the tab activity that started the activity group.

setTitle should work for the activity window which is held by the tabactivity. The sub activities are rendered in the framelayout of the tab activity. So in the child activities access the parent tab activity to set the title.
