android - 回收站 View 项目不滚动？

Question

我正在处理 Recycler View ，在这里我将三个回收器 View 水平放置在布局中。问题是第二个和第三个回收器 View 项目显示但无法滚动，即使在内部使用嵌套滚动并特此附加xml。请建议我如何滚动第二个和第三个回收器 View 。

还将您的 Java 代码发布到您初始化回收站 View 的位置。另外，尝试从嵌套 ScrollView 中删除回收器 View (您可以在没有嵌套 ScrollView 的情况下放置它们)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rightLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">
    <LinearLayout
        android:id="@+id/lay1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="#ff0000">
        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerViewmonth"
            android:layout_width="match_parent"
