title: onKeyDown or onBackPressed in a parent activity
body: <p>I have a <a href="http://developer.android.com/reference/android/app/TabActivity.html" rel="nofollow">TabActivity</a> that shows other <a href="http://developer.android.com/reference/android/app/Activity.html" rel="nofollow">Activities</a> as the content based on which tab is selected. What I want to do is from the 'parent' Activity try to capture the back key press, but neither <a href="http://developer.android.com/reference/android/app/Activity.html#onKeyDown%28int,%20android.view.KeyEvent%29" rel="nofollow">onKeyDown()</a> nor <a href="http://developer.android.com/reference/android/app/Activity.html#onBackPressed%28%29" rel="nofollow">onBackPressed()</a> ever get called in the parent... it's being handled by the 'child' Activities. Is there any way to have it pass up to the 'parent' Activity?</p>
