Answer 1

尝试将“ RecyclerView.VERTICAL，false”添加到LinearLayoutManager初始化中，如下所示 LinearLayoutManager（上下文，RecyclerView.VERTICAL，false） 还要确保适配器已正确初始化（在useAdapter初始化后尝试添加日志）

Answer 2

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/rv_hashtags"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
    android:orientation="horizontal"
    tools:listitem="@layout/item_trending"/

检查您正在使用的上下文。如果其为null，则适配器可能无法连接，并且可能发生上述错误
app：layoutManager =“ androidx.recyclerview.widget.LinearLayoutManager”此行可以帮助您摆脱上述错误。
