Hiding Cardview until search is initiated

Question

I've followed the code on http://www.camposha.info/source/android-recyclerview-search-filter and made my search filter work. The only thing I need is when opening the activity to keep the Cardview hidden, or invisible until the search has started in the searchbar (in other words, to keep the Cardview hidden until I start typing something in the searchbar). I have read the comments which I should have edited the Edittext but I don't have it. what should I do?

Answer 1

Keep the cardview's visibility gone in the layout. And add a queryTextListener to your searchView

yourSearchView.OnQueryTextListener() {
    @Override
    public boolean onQueryTextChange(String newText) {
        if(newText.length()>0){
        yourCardView.setVisibility(View.VISIBLE);
        }else{
        yourCardView.setVisibility(View.GONE);
        }
        return true;
    }

    @Override
    public boolean onQueryTextSubmit(String query) {

        return true;
    }
}
