我做了一个适配器，但它无法连接

如何解决我做了一个适配器，但它无法连接

我制作了一个适配器来制作回收器视图。但是会出现适配器未连续连接的错误。我确实做到了，为什么我不能？我预测这是一个线程问题，但我不知道如何解决它。请帮帮我。

public class RoomActivity extends AppCompatActivity {

错误信息如下。 RecyclerView：没有附加适配器；跳过布局

解决方法

嗨，我认为错误已经说明这里出了什么问题。您是否尝试将适配器添加到 RecyclerView 的 rvFloor onCreate？

如果没有，你可以做的是设置一个新的适配器来按需提供子视图。由于在 onCreate 上设置一次适配器就可以完成这项工作，我认为您还应该在定义视图后调用 init()

rvFloor.setAdapter(floorAdapter);
