title: How to make home button change to another activity
body: <p>I'm new to Eclipse and I wanted to see if this was possible.</p>
  
  <p>What I want to do is make a guest mode. When a user uses my app there will be a textBox and a Button. When the user puts in their phone number of choice, I want it to change to the dialer. When the home button is pressed, I want the home button to be redirected to a password activity. How do I do this?</p>
  
  <p>edit- Okay, so maybe I wasn't clear what I meant for my app to do. It's a guest mode so that say that someone asks to use your phone. You can go to this app and they put whoever they want to call in the textbox. When they are finished with their call, it changes to a password activity. That help, or do I need to set it to where when the call ends it changes to the password activity?</p>
