Rolagem suave e Fling com NestedScrollView, AppBarLayout e CoordinatorLayout
Estou trabalhando em um aplicativo em que estou usando o AppBarLayout com CollapsingToolbarLayout e NestedScrollView. Eu implementei isso com sucesso e está funcionando bem.
Agora, o que estou tentando fazer é que, ao jogar (deslize rapidamente para cima) no Nestedscrollview, ele role completamente para o topo. Da mesma forma, ao atirar (deslize rapidamente para baixo) em direção à parte inferior da tela, ela deve rolar até a parte inferior suavemente. No entanto, agora, ele só fica preso no meio, o que a torna feia. Eu tentei muitas soluções disponíveis aqui, mas nada funcionou para mim. Minha configuração atual está abaixo.
