New for Android: dynamically changing views

Question

I am trying to learn how to create Android applications.

The first simple application to become a component of the larger application that I hope to build is to have a button on the screen where, when clicked, it adds something new to the view.

For instance:

Imagine a layout that has only a button:

[Create!]

When this button is pressed, a new line appears in the view, added to it:

[Create!]
A Something!

Subsequent clicks add more lines

[Create!]
A Something!
A Something!

Etc.

I made a LinearLayout and put a button in it, and attached a click listener to it. This all works great. I can’t figure out how to get the LinearLayout handle in the onClick function, with which I will add () a new TextView that says "A Something!"
