NestedScrollView не показывает все содержимое

Question

Я пытаюсь использовать ScrollView для моей mainActivity .Внутри ScrollView используется горизонтальная LinearLayout .Содержимое LinearLayout превышает размер экрана.Я ожидал, что смогу прокрутить их внутри ScrollView, однако, ScrollView показывает только несколько пикселей ниже последнего вида, который просеивается на экран.Мне нужно, чтобы он показывал и прокручивал все содержимое.

Answer 1

Я решил эту проблему.Я обнаружил, что после удаления всех weightSum s и layout_weight s мой ScrollView работал отлично.
