how to get the time between User input text twice?

Question

I use SearchView in my android app, I monitor the onQueryTextChange event, what i don't want to filter the result when every time user input text, I want to filter the result only when User want to filter, I solution is to get the time every time user input text, when the time is bigger than 1s, I will query the result for the search, How can I do that?

Answer 1

You can create a timer that resets every time the input changes.

Timer mTimer;

...

public boolean onQueryTextChange (String newText) {
    if (mTimer != null) {
        mTimer.cancel();
    }
    mTimer = new Timer();
    mTimer.schedule(new TimerTask() {
        @Override
        public void run() {
            search(newText);
        }
    }, 1000);

    ...
}

You could also use onQueryTextSubmit to search only when the user wants to.
