How to show a view for 3 seconds, and then hide it?

Question

I tried with threads, but android throws \"CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.\".

So how can

Answer 1

There is an easier way to do it: use View.postDelayed(runnable, delay)

View view = yourView;
view.postDelayed(new Runnable() {
        public void run() {
            view.setVisibility(View.GONE);
        }
    }, 3000);

It's not very precise: may be hidden in 3.5 or 3.2 seconds, because it posts into the ui thread's message queue.

Use post() or runOnUiThread() just something as setTimeout().
