You need to change the logo and the title in action bar.

You can use

getActivity().getActionBar().setTitle("your title");

and

getActivity().getActionBar().setLogo(your draw id);

It is very easy to do ..

There's lot's of way to do this task as defined above .. but I will suggest to make use of custom view for Action bar(As this will work on all devices as same) .. this will let you create much more complex view's in a very handy and easy way.

For your query you make make use of custom views for ActionBar..

You can create customized action bar like this ..

actionBar = getSupportActionBar();
actionBar.setCustomView(R.layout.xyz); // Set custom view like this 
// In your case you want an icon ... 
ImageView image = (ImageView) actionBar.getCustomView().findViewById(R.id.fare_ll); // Get id of custom view like this

Also you need to set this property ..

actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);

// Now you can do any sort of stuffs with this icon .. like you can perform click functionality

Here's your xyz.xml file .. This file is just for your reference purpose .. this will let you know how to create custom view for Action Bar. :)

You need to use the following code to get this:

private ActionBar actionBar;

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        actionBar = getActionBar();
        actionBar.setTitle("");
        actionBar.setLogo(R.drawable.logo); //logo needs to be defined in the drawables folder.
}
