You should generally explain what "doesn't work" means, but I can tell from
your code that you're locking the UI and getting an ANR, right?
You can't just do "while (some condition that has just been set to true)"
within the main thread. That puts you in an infinite loop and gets you
stuck. You need to do something like this:
onMotionEvent(View view)
{
if (action down)
{
// Pressed down on a button, save it and start the scroll timer
(onTimerTick)
viewClicked = view;
startScrollTimer();
}
else if (action up)
stopScrollTimer(); // Released the button, stop the timer (and thus the
scrolling)
}
onTimerTicker()
{
if (viewClicked == left)
scrollLeft();
else if (viewClicked == right)
scrollRight();
}
There are multiple ways to do the timer logic, Kostya showed you one.
