Android 使用“警报”对话框更改Reyclerview布局

我有一个应用程序在列表布局中已经有一个RecyclerView。此RecylcerView还具有从alertDialog调用的各种筛选器。我希望能够从这个alertDialog更改RecyclerView的布局

我已经更新了

对话框_layout.xml

以包含按钮，并更新了

main活动

创建了两个布尔变量

liststate

和

gridstate

，这两个变量由新按钮触发的两个onclicklistener更新。（我知道它们不需要是布尔值，但我将它们用于其他按钮，因此处理装饰，因此我认为我也会在这里使用它们）

我已经创建了一个

layout\u listitem\u grid.xml

，与原来的类似，但不是正方形

<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="150dp"
  android:layout_height="150dp"
  app:cardElevation="10dp"
  app:cardUseCompatPadding="true">

  <RelativeLayout
      android:id="@+id/parent_layout"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_marginLeft="@dimen/margin_card_left_right"
      android:layout_marginRight="@dimen/margin_card_left_right"

      android:clickable="true"
      android:paddingLeft="@dimen/activity_margin_left"
      android:paddingTop="@dimen/row_padding"
      android:paddingRight="@dimen/activity_margin"
      android:paddingBottom="@dimen/row_padding">


      <ImageView
          android:id="@+id/grid"
          android:layout_width="match_parent"
          android:layout_height="150dp"
          android:adjustViewBounds="true"
          android:contentDescription="@string/app_name"
          android:scaleType="centerCrop" />

      <TextView
          android:id="@+id/image_name"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_centerInParent="true"
          android:layout_marginLeft="@dimen/activity_margin"
          android:layout_toRightOf="@+id/image"
          android:fontFamily="@font/baloo"
          android:text="text"
          android:textSize="@dimen/heading" />
  </RelativeLayout>
</androidx.cardview.widget.CardView>

我需要如何更改

RecycleServiceAdapter

，我正在寻找最简单的方法，我知道我必须更新支架等，但我也希望过滤器在使用后仍能正常工作，迄今为止我所做的每一种方法都会破坏它们

我知道我的代码可能不美观，也不传统，但目前它仍在工作，所以我希望保持这种状态是可能的
