我创建了一个列表。其中我显示了费用金额、费用类型、费用类别和费用时间。
我使用了具有多种 View 类型的RecyclerView，对于 View 类型1，我显示了一个小圆圈，而 View 类型2则显示了一个大圆圈。
费用类型是显示两个不同的圆圈，一个小的代表时间，一个大的代表日期。两者我都可以看到。
但现在我想在小圆圈上给出不同的颜色，即根据时间给出不同的颜色。问题是我可以看到只有黄色的圆圈，填充了黄色，表示 12:30，显示时间，其他圆圈是空白的，没有颜色没有时间，只有边框。

items.add(new Expense("2000", "drink", 1,"10:30"));

}
}
仅比较 12:30 时间，其他时间被跳过。为什么会发生这种情况？
最佳答案
你的内心状况
public void onBindViewHolder(ItemViewHolder itemViewHolder, int i) : if(TYPE1==i)
仅当i==1时才有效。也许这不是你想要的。条件应如下所示:
if (TYPE1==getItemViewType(i))
