Re: [android-developers] override back button

[Justin Anderson]

Starting with Android 2.0 you also need to implement onBackPressed() in
order to achieve this...

And on second review of your code, I see you only do that if the key is not
the back key. Don't mind me.

The "super" method likely executes the default action for the given key
press.
The default action on the back key is to call finish() on the activity.

Re: [android-developers] override back button

Hello,

Does your Back Button exit the application in both cases? When
animation.state!=1 it should not do anything.  In the other case it should
exit.

>From documentation:

   - "If you handled the event, return true. If you want to allow the event
   to be handled by the next receiver, return false."

Hope this helps.

[android-developers] override back button

[Colin]

Can someone help me understand how to stop the back button from
exiting out of my program?  I want it to just return to my main menu
or exit if pressed on the main menu but when I override the method it
still exits.  Here is what I currently have:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)  {
if (keyCode == KeyEvent.KEYCODE_BACK && 
event.getRepeatCount()
== 0) {
if (animation.state != 1){
animation.state = 1;
return true;
}
else return false;
}

return super.onKeyDown(keyCode, event);
}

I have messed with it a little but my program is always still closes.
