GridLayout Not Displaying Last Column

Question

I have a layout that contains a GridLayout with 3 columns. However, it refuses to display the last column. My current code shows the following in the designer (the blue & orange areas are RecyclerViews):

My last (3rd, which is a GridLayout) column is not displayed. If I swap the layout_column values of the 2nd & 3rd columns, I get the following:

As you can see, it still shows only (what is now) the 2nd column. Also, notice that in the first screenshot, the gray rectangle at the bottom (which is a FrameLayout with a layout_columnSpan of 3) goes offscreen, while in the second one, it fits, even though no code in that View is changed. If I remove the GridLayout completely, everything looks good (except for the fact that I do not have everything I need in my layout!). The RecyclerViews (the blue & orange areas) have layout_columnWeight="1" & layout_width="0dp", and it looks to me like it is calculating their width before laying out the GridLayout in the 3rd column, but I am not sure how to fix that. What is the problem? Thanks.

Hello njsokalski,​

Welcome to our Microsoft Q&A platform!

How do you define the layout.xml? Could you please post the related code? I create a basic demo to test the function, it works as expected. Here is the sample code, you could refer to it.

   <GridLayout  
       android:rowCount="1"  
       android:columnCount="3"  
       android:layout_width="match_parent"  
       android:layout_height="match_parent">  
     
       <!--the first column-->  
       <TextView  
           android:text="the first column"  
           android:layout_row="0"  
           android:layout_column="0"  
           android:layout_width="wrap_content"  
           android:layout_height="wrap_content"/>  
     
       <!--the second column-->  
       <androidx.recyclerview.widget.RecyclerView  
           android:layout_row="0"  
           android:layout_column="1"  
           android:layout_columnWeight="1"  
                 
           android:background="#ff00"  
           android:id="@+id/recyclerView1"  
           android:layout_width="0dp"  
           android:layout_height="match_parent"/>  
     
       <!--the third column-->  
       <GridLayout  
           android:background="#ff0"  
           android:layout_row="0"  
           android:columnCount="1"  
           android:layout_column="2"  
           android:rowCount="2"  
           android:layout_width="wrap_content"  
           android:layout_height="match_parent">  
           <!--the content-->  
       </GridLayout>  
     
   </GridLayout>
