Anthony,
There is only one content view per activity. If you change it, then
change back, then you need to obtain new UI element references by
calling findViewById all over again.
Second, if "android.intent.action.CODE" is your own action string, don't
start it with "android".
Third, you can handle the back button if needed by overriding onKeyDown
and checking for "keyCode == KeyEvent.KEYCODE_BACK".
Hope this helps.

Not sure if I am doing this right, but here is what I am trying to do.
I got my CodeActivity(Code Below) that assigns a bunch of buttons.
On button 4, I pull up another contentView to display some buttons
under that particular button.
Then on the button 4(or the back button) I want to return to the
previous page of the CodeActivity.
If i hit the back button, the app exits so I tried putting a back
button on the form and setting it back to the original contentview but
then the buttons didn't work for the original codeactivty page.
I need another pair of eyes to help me work through this issue.
