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;
}
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;
}
