SearchActivity

// I have created this SearchActivity based on a RecyclerView but when I click on an Item on the list I get a NPE:

/* java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object java.util.ArrayList.get(int)' on a null object reference */

the error is caused by this part of code:

ItemClickSupport.addTo(rv).setOnItemClickListener(new ItemClickSupport.OnItemClickListener(){
            @Override
            public void onItemClicked(RecyclerView recyclerView, int position, View v) {
                Intent intent = new Intent(SearchActivity.this, ChordActivity.class);
                Bundle bundle = new Bundle();
                bundle.putParcelable("selected", filteredModelList.get(position)); //HERE IS THE ERROR
                intent.putExtras(bundle);
                startActivity(intent);
            }
        });

The filter it is based on is this one:

private List<Accordo> filter(List<Accordo> models, String query) {
        query = query.toLowerCase();

        filteredModelList = new ArrayList<>();
        for (Accordo model : models) {
            final String text = model.getName().toLowerCase();
            if (text.contains(query)) {
                filteredModelList.add(model);
            }
        }
        return filteredModelList;
    }

IMPORTANT: the error accours ONLY when I got the whole list, when it is NOT FILTERED. If I type anything and filter the list and then click on the Item the error does not accour.
