You can define the label for each activity in your manifest file.

A normal definition of a activity looks like this:

Where title text should be replaced by the id of a string resource for this activity.

You can also set the title text from code if you want to set it dynamically.

setTitle(address.getCity());

with this line the title is set to the city of a specific adress in the oncreate method of my activity.
