你应该将你的RecyclerView LayoutManager设置为Gridlayout模式。当你想要设置你的RecyclerView LayoutManager时，只需更改你的代码:

recyclerView.setLayoutManager(new GridLayoutManager(getActivity(), numberOfColumns));

在RecyclerView初始化中设置

recyclerView.setLayoutManager(new GridLayoutManager(this, 4));

你应该将你的RecyclerView LayoutManager设置为Gridlayout模式。当你想要设置你的RecyclerView LayoutManager时，只需更改你的代码:

recyclerView.setLayoutManager(new GridLayoutManager(getActivity(), numberOfColumns));

如果你想在reyclerview的XML文件中设置网格布局，那么你可以把这两个放在recyclerview XML中。

app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
app:spanCount=numberOfItemsInSignleRow

如果你想从Java代码中设置网格布局，你可以这样写。

recyclerView.setLayoutManager(new GridLayoutManager(getActivity(), numberOfItemsInSignleRow));

    There are 2 ways to achieve this 
    
    - In Xml
     <androidx.recyclerview.widget.RecyclerView
                            android:id="@+id/list_amenities"
                            android:layout_width="0dp"
                            android:layout_height="wrap_content"
                            android:layout_marginTop="@dimen/_8sdp"
                            android:nestedScrollingEnabled="false"                 
 app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
                            app:spanCount="2"
app:layout_constraintEnd_toEndOf="@+id/text_parking_lot_amenities"                       app:layout_constraintStart_toStartOf="@+id/text_parking_lot_amenities"                  app:layout_constraintTop_toBottomOf="@id/text_parking_lot_amenities" />

跨度计数用于网格列 -在活动中

 listAmenities.layoutManager = GridLayoutManager(this, TWO)
 here TWO indicates number of grid columns

在MainActivity中，也就是你分配回收器视图的地方，使用这段代码。

recyclerView = findViewById(R.id.recycler_view);
    recyclerView.setHasFixedSize(true);
    //recyclerView.setLayoutManager(new LinearLayoutManager(this));
    recyclerView.setLayoutManager(new GridLayoutManager(this, 2));
