Как парсить ссылку, только если из поиска пришло значение и оно не пустое? Проблема в том, что даже ссылка без значения в конце дает результат

А мне нужно отображать значения только если в конце идет значение из searchView, как это правильно организовать? Я пробовал это так но это не работает!

}
@Override
