RecyclerView With GridLayoutManager Not Scrollable

Nathan Sokalski 4,116

I have 2 RecyclerView(s): One using a LinearLayoutManager, one using a GridLayoutManager. The LinearLayoutManager works great, and allows me to scroll vertically as I want. The GridLayoutManager, however, refuses to scroll. Here is the xml for the RecyclerView with a GridLayoutManager:

<androidx.recyclerview.widget.RecyclerView android:id="@+id/rvHomeData" android:layout_width="wrap_content" android:layout_height="0dp" android:layout_column="1" android:layout_row="1" android:layout_rowWeight="1"/>

When I run my app, the RecyclerView's items are cropped to make all items visible rather than allowing the user to scroll. Here is the code used to set the GridLayoutManager:

this.rvHomeData.SetLayoutManager(new GridLayoutManager(this, 33, GridLayoutManager.Horizontal, false));

How can I make the RecyclerView with a GridLayoutManager scroll rather than crop the items?

I thought the 33 was for how many elements should exist per column (when to wrap)? But it seems like (and what it sounds like you are saying) is how many should be visible. When I change the number to a smaller value like 2 (or 3 or 4), not only is my data not arranged the way I want, but the scrolling is horizontal. You also use the phrase crowded together, but I want my data to be adjacent (no spacing between items), so I want my data crowded together, just not resized.

I tested with the following official example and your GridLayoutManager parameter and reproduced the issue.

RecyclerViewer.

The reason for this is on the 33 parameter, which indicates how many elements we want RecyclerView to display on a page, so when I change it to 2, the page elements are no longer crowded together and can be slided normally.

Thanks for your feedback.

In XAML, you could change android:layout_height="0dp" to android:layout_height="wrap_content" and GridLayoutManager.Horizontal to GridLayoutManager.Vertical to allow your RecyclerView to scroll vertically.

Will this make your program work as expected?

Your prompt reply will be highly appreciated.
