Android 包含列表视图的Cardview
我使用了CardView来显示图片，我想在CardView中添加一个ListView来显示这些图片的评论。对于CardView，我使用了RecyclerView适配器，并且在片段中使用了CardView和RecyclerView。但是列表视图没有显示在CardView中 CardAdapter.javaAndroid 包含列表视图的Cardview,android,material-design,Android,Material Design,我使用了CardView来显示图片，我想在CardView中添加一个ListView来显示这些图片的评论。对于CardView，我使用了RecyclerView适配器，并且在片段中使用了CardView和RecyclerView。但是列表视图没有显示在CardView中 CardAdapter.java public class CardAdapter extends RecyclerView.Adapter<CardAdapter.ViewHolder> { List<Na

谢谢您是否尝试将listView包装为相对布局？然而，如果我没弄错的话，那么你的卡片就是一排的回收者视图？将一个listView放在另一个listView（或recyclerview）中会很痛苦。也许重新考虑一下设计。你需要提供一些代码，因为它可能是导致它不显示的原因。它不显示是因为你不能将一个可滚动视图添加到另一个视图中。您的解决方案将不起作用，您应该考虑另一种方法。您可以在cardview中使用recyclerview，而不是listview。检查这个答案
