[FIXED] Throttle onQueryTextChange in SearchView

Issue

What's the best way to "throttle" onQueryTextChange so that my performSearch() method is called only once every second instead of every time the user types?

public boolean onQueryTextChange(final String newText) {
    if (newText.length() > 3) {
        // throttle to call performSearch once every second
        performSearch(nextText);
    }
    return false;
}

Solution

I ended up with a solution similar to below. That way it should fire once every half second.

        public boolean onQueryTextChange(final String newText) {

            if (newText.length() > 3) {

                if (canRun) {
                    canRun = false;
                    handler.postDelayed(new Runnable() {
                        @Override
                        public void run() {

                            canRun = true;
                            handleLocationSearch(newText);
                        }
                    }, 500);
                }
            }

            return false;
        }
