我在一个RecyclerView中显示了3部分数据：
storyList yukulList homeList 当我尝试仅在storyList中显示yukulList或homeList或RecyclerView数据时，它可以工作。但是，当我尝试显示多个数据时，例如：storyList && yukulList或storyList && yukulList && homeList，它将显示
java.lang.IndexOutOfBoundsException。
我尝试添加notifyDataSetChanged()，但是它不起作用。

答案 0 :(得分：0)
尝试使用三个不同的回收站视图，每个数据一个，在主布局中，将每个回收站视图的高度设置为0dp，重量为0.3，这将使每个回收站具有相同的高度，并且非常适合任何屏幕
答案 1 :(得分：0)
尝试删除此recyclerView.setHasFixedSize（true）或将FALSE传递给它。将TRUE传递给此方法意味着您的适配器的对象内容不会更改，但是这里您通过对适配器的内容执行查询来更改适配器的内容。
答案 2 :(得分：0)
在您的适配器中，collection列表是使用position安全访问的唯一列表。尝试调用yukulList.get(position)可以确保最终引发异常。
onBindViewHolder()中的所有这些行都是不安全的，应更改：
@Override public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) { // ... ((tidurViewHolder) holder).bind(storyList.get(position)); // ... ((yukulViewHolder) holder).bind(yukulList.get(position)); // ... ((homeViewHolder) holder).bind(homeList.get(position)); // ... }
您可以通过调用getItemViewType()来访问从holder.getItemViewType()返回的“视图类型”值，并可以使用该值来确定要使用的正确视图类型和项：< / p>
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {
Object item = collection.get(position);
int adapterPosition = holder.getAdapterPosition();
if (holder.getItemViewType() == VIEW_TYPE_TIDUR){
Story story = (Story) item;
tidurViewHolder vh = (tidurViewHolder) holder;
vh.bind(story);
vh.setViewData(story, adapterPosition);
} else if (holder.getItemViewType() == VIEW_TYPE_YUKUL){
YukulModel yukul = (YukulModel) item;
yukulViewHolder vh = (yukulViewHolder) holder;
vh.bind(yukul);
vh.viewDataYukul(yukul, adapterPosition);
} else if (holder.getItemViewType() == VIEW_TYPE_HOME){
HomeModel home = (HomeModel) item;
homeViewHolder vh = (homeViewHolder) holder;
vh.bind(home);
vh.viewDataHome(home, adapterPosition);
}
}
还要注意，实际上不需要将holder.getAdapterPosition()传递给setViewData()，因为您可以简单地从getAdapterPosition()方法中调用tidurViewHolder。
我还要说的是，您可以将bind()和setViewData()的呼叫合并为一个，这样就可以了：
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {
Object item = collection.get(position);
if (holder.getItemViewType() == VIEW_TYPE_TIDUR){
((tidurViewHolder) holder).bind((Story) item);
} else if (holder.getItemViewType() == VIEW_TYPE_YUKUL){
((yukulViewHolder) holder).bind((YukulModel) item);
} else if (holder.getItemViewType() == VIEW_TYPE_HOME){
((homeViewHolder) holder).bind((HomeModel) item);
}
}
