How do I create a help overlay like you see in a few Android apps and ICS?

by

Let’s assume you ordinarily would call setContentView(R.layout.main), but on first run, you want to have this overlay.

Step #1: Create a FrameLayout in Java code and pass that to setContentView().

Step #2: Use LayoutInflater to inflate R.layout.main into the FrameLayout.

Step #3: Use LayoutInflater to inflate the overlay into the FrameLayout.

Step #4: When the user taps the button (or whatever) to dismiss the overlay, call removeView() to remove the overlay from the FrameLayout.

Since the overlay is a later child of the FrameLayout, it will float over top of the contents of R.layout.main.
