问题描述
我正在尝试在其中的RecyclerView父级中创建一个混合项，其中包含一些CardViews并在其中包含另一个RecyclerView.如果还看不到，请想象RecyclerView中有几个ListViews(ListViews由标题分组).
I'm trying to create a mixed items in a RecyclerView parent, within it, contains some CardViews with another RecyclerView inside it. If you can't see it yet, imagine several ListViews inside a RecyclerView (with the ListViews being grouped by a Header).
这里是我为了使其更清晰而绘制的结构:
Here is a structure that I've drawn to make it more clear:
以上是我要实现的布局结构.请注意，这仅是计划.我不确定将RecyclerView包含在RecyclerView中是否是一个好主意.
Above is the layout structure that I'm trying to achieve. Please note that this is only the planning. I'm not sure if it is a good idea to have a RecyclerView within a RecyclerView.
到目前为止，我已经尝试使用 ExpandableRecyclerView 来实现这种复杂的布局.但是问题是，当在RecyclerView中添加其他项目类型时(例如，水平滚动轮播)，它会隐藏在Header中.
So far, I've tried using ExpandableRecyclerView to achieve this kind of complex layout. But the problem is when adding a different item type in the RecyclerView (eg. a horizontal scroll carousel), it is hidden within the Header.
我现在想不出其他任何方式.你们对如何实现这种布局有什么建议吗?
I can't think of any other ways now. Do you guys have any suggestions on how to achieve this layout?
为简单起见，如果您理解我的意思，它是RecyclerView父级中子CardView中的RecyclerView部分.
To make it simple, it is a sectioned RecyclerView within a child CardView inside a RecyclerView parent, if you understand what I mean.
推荐答案
不建议在另一个RecyclerView中使用RecyclerView.但是，如果您想使用嵌套的RecyclerViews实现上述目的，则可以使用布局管理器，将最里面(绿色)的RecyclerView包裹RecyclerView到其内容的高度.在 https://github.com/serso/android-线性布局管理器
Having a RecyclerView within another RecyclerView is discouraged. However if you want to achieve the above using nested RecyclerViews, you can use a layout manager that wraps the RecyclerView to its content's height for the innermost (Green Coloured) RecyclerView. There is one such layout manager already available at https://github.com/serso/android-linear-layout-manager
还请确保通过如下设置onTouchListener来禁用最里面的RecyclerView上的触摸手势.
Also make sure to disable touch gestures on the innermost RecyclerView by setting an onTouchListener as follows.
mRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener {
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
return true;
}
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
});
