re: only handle key up if i trap key down -- gotcha. re: handling a key up only if someone else is not doing so this is what I'm seeing -- in Android 1.5 and 1.6, in my Activity, onKeyUp() is not called if a textview is selected in my activity (i.e. has the selection state). In that case, i presume the textview is consuming the key events. in Android 2.0, in my Activity, onKeyUp() is called **even if** the textview is selected in my activity.
