我的serviceId数组包含firestore集合的documentId。通过使用此ID，我想从其他集合中获取详细信息并必须在recyclerview中填充它。
问题： i）我可以使用该ID来从其他集合中获取详细信息，但有时会获取其第二个Documentid值，因此当我选择该项目下的某个项目时，该项目将被选中，而不是选定的一个
ii）仅在某些情况下会发生此问题。如果运行该应用程序正常运行10次，剩余时间运行6次，则其值输入错误。
iii）我正在将documentid从片段传递到适配器，同时我检查了数组中的值，其值始终相同，并且没有变化。
答案 0 :(得分：0)
RecyclerView与GridView的不同之处在于，该名称暗示它回收视图，而不是为每个数据项创建一个视图。
因此解决方案是您在适配器中使用以下方法：
@Override
public int getItemViewType(int position) {
return position;
}
