问题描述
这个问题是针对新的 ViewPager2 类的.
This question is for the new ViewPager2 class.
有一个 旧 ViewPager 的类似问题，但解决方案需要扩展 ViewPager.但是，ViewPager2 是最终版本，因此无法扩展.
There is a similar question for the old ViewPager, but the solution requires extending ViewPager. However, ViewPager2 is final so cannot be extended.
在我的情况下，我有一个包含三个不同片段的 ViewPager2.其中一个片段比其他两个片段高得多，这意味着当您滑动到其中一个较短的片段时，会有很多空白空间.那么如何有效地将 ViewPager2 包裹到当前 Fragment 的高度呢?
In my situation, I have a ViewPager2 that contains three different fragments. One of these fragments is much taller than the other two, which means when you swipe to one of the shorter fragments, there is a lot of empty space. So how do I effectively wrap the ViewPager2 to the height of the current fragment?
推荐答案
解决方案是在 ViewPager2 的每个片段中添加以下内容:
The solution is to add the following in each fragment that is part of the ViewPager2:
override fun onResume() {
super.onResume()
binding.root.requestLayout()
}
binding.root 来自 ViewBinding/DataBinding 但它是布局的主要容器，即 ConstraintLayout、LinearLayout 等.
binding.root is from ViewBinding/DataBinding but it's is the main container of your layout, i.e. ConstraintLayout, LinearLayout, etc.
