i can't set title to Action bar sherlock. Here is my code:

```
public void addNavaigationBar(){

       //Create Action Bar sherlock
ActionBar navigation_bar =  getSupportActionBar();

//Setting standart navigation bar view
navigation_bar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);

navigation_bar.setDisplayHomeAsUpEnabled(true);
navigation_bar.setDisplayShowTitleEnabled(true);
navigation_bar.setTitle("Testing");

}

```

I want to add Testing tile but it don't changes. This should be easy but i can't find it.

Also i am wondering if i could create this navigation bar on top and Tab bar on bottom with Action bar sherlock ? 

Thanks.

EDIT:
Sorry this is working, it's my other mistake.
