Erel, DonManfred, aeric and Computersmith6, thank you for your replies. You make this a great forum. I asked this question because it appears that, when I release my app on Google Play, its testing robot pokes my buttons many times during its test, and my concern is I might get flagged for not releasing memory, or something.
But I do know, if I keep pressing the same button over and over, eventually performance begins to slows down. This is telling me that something is accumulating in memory (filling a buffer or something?), and affecting performance.
Perhaps there is another way to achieve my goal, but I like the way the loadlayout swoops into the display. It's pretty cool, and I don't have to add extra logic to make it do that. And the user may want to visit the same button multiple times to re-read the text. Understand though, this isn't a critical issue for a user. They would never push the same button enough times to cause this, but it does look to me that there is something not right.
Also, aeric, thank you very much - you mentioned "RemoveAllViews". I need to research that. On the smaller cellphone displays, I have to load the 2nd layout on top of those buttons and it appears the Google robot can poke them even when they're covered by that 2nd layout. I need to figure that out too. I have tried "view".enabled = false/true to off the buttons in that case, but that created other program flow issues for me.
