Android Question [SOLVED] Change program name in upper left corner

[nypaulie]

In one program I wrote I was able to use Activity.Title to assign its name. In another one however adding the line "Activity.Title = Some Name" It doesn't "take".
The second program was written by recoding an existing one, and That title appears instead of the one coded in the "Activity.Title" line.
Here's a screenshot. I included he pic on the right which shows how my first program displays the correct title.
[ADDED LATER] - This was solved thanks to the response from "anOparator" which follows.

For each Activity I use the Designer,
in each Layout file I highlight Activity, the forth Property is Title, there I give a relevant title to each activity. I've gotten into the habit of insuring I'm on the selected Activity before I edit it's Layout file.
This happens to be my preferred way, I'm sure there may be other ways.

Thank you. Your answer fixed it for me when you said "the 4th Property". I had the line as the 3rd entry, when I swapped it to 4 it worked. Here's the new screenshot.
