Delay call to onQueryTextChange() in SearchView.OnQueryTextListener with SearchView

Question

Using a SearchView in my application.

Is there anyway in which I can make the call to onQueryTextChange() method delayed. Like, when user type a sequence o

Answer 1

1) Create abstract class:

public abstract class DelayedOnQueryTextListener implements SearchView.OnQueryTextListener {

    private Handler handler = new Handler();
    private Runnable runnable;

    @Override
    public boolean onQueryTextSubmit(String s) {
        return false;
    }

    @Override
    public boolean onQueryTextChange(String s) {
        handler.removeCallbacks(runnable);
        runnable = () -> onDelayerQueryTextChange(s);
        handler.postDelayed(runnable, 400);
        return true;
    }

    public abstract void onDelayerQueryTextChange(String query);
}

2) Set it like this:

searchView.setOnQueryTextListener(new DelayedOnQueryTextListener() {
    @Override
    public void onDelayerQueryTextChange(String query) {
        // Handle query
    }
});
