Filter has a overridden method with Filter.FilterListener which you can use .

search.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            adapter.getFilter().filter(inputSearch.getText().toString(),new Filter.FilterListener(){
                @Override
                public void onFilterComplete(int count) {
                    if (count == 0){
                        // List empty
                    } else {
                        // List has data
                    }
                }
            });
        }});
