Остановка прокрутки Nested Scroll View в определенной точке в Android

/ 31 мая 2019

Я проектирую пользовательский интерфейс с двумя вложенными представлениями прокрутки во вложенном представлении прокрутки.Я не могу остановить прокрутку первого вложенного представления прокрутки в определенной точке, не нарушая второе представление прокрутки.

Я попытался использовать myNestedSrollView.scrollTo (0, guidline.getTop ()), но это не таквнесите любые изменения в текущий шаблон прокрутки.

Вот мой дизайн макета:
