如何将 ViewPager2 与 CollapsibleToolbar 布局一起使用
How to use ViewPager2 with CollapsibleToolbar layout
我正在尝试使用 collapsible toolbar
布局实现一些目标,我有 2 个带有 viewPager2
的选项卡
以下是 expanded screenshot and collapsed screenshot.
情况下的两张图片
下面是我在 XML 中的代码,不确定哪里出错了...在这种情况下我的卷轴无法正常工作。我希望工具栏在折叠时保持在顶部
我尝试在 AppbarLayout
中添加 toolbar
,但没有成功。
也试过下面的链接
不知何故对我不起作用 Link2

ViewPager2
在 NestedScrollView
中无法正常工作,因为其内部 RecyclerView
默认启用嵌套滚动。
要修复错误行为,您需要以编程方式禁用 ViewPager2
RecyclerView
的嵌套滚动,因为它在布局中不可访问:
科特林:
viewPager.children.find { it is RecyclerView }?.let {
(it as RecyclerView).isNestedScrollingEnabled = false
}
Java:
for (int i = 0; i < viewPager.getChildCount(); i++) {
View child = viewPager.getChildAt(i);
if (child instanceof RecyclerView) {
((RecyclerView) child).setNestedScrollingEnabled(false);
break;
}
}
