我有问题而且我不知道如何解决它。 那么,如何使CollapsingToolbar中的ImageView过度滚动? 例如,
CoordinatorLayout
-- AppBarLayout
-- CollapsingToolbarLayout
----30% Non visible part----
----40% Visible part, center of image----
----30% Non visible part----
--NestedScrollView <-- Here content
当用户按图像向下拍摄时,如何使图像可见部分图像更大?我试图将imageview包装成scrollview并进行过度滚动,但图像被裁剪。 有什么想法吗?
