How to trigger the ClassCastException - cannot be cast to android.widget.AbsListView$LayoutParams in android with List Fragment?

I have seen a lot of similar issues with this exception, but it is strange neither of them fits me. I'm not sure where the issue is.

What I have done: I have the Main Activity which is a drawer layout having a bottom navigation bar one of its menus directs to the System Activity(mentioned below) and it has a coordinatorlayout as mentioned below. Inside System Activity, there are a couple of fragments, and every other function works well except when I select an item in the First Fragment (SystemFragList - mentioned below) I get this strange exception.

My Attempt 1: For the first fragment(SystemFragList) of my System Activity I have 1st added a grid view and I wanted to pass the corresponding parameter(like the selected name) to other fragments when I select one grid view item. Grid view was created with a base adapter having an image and a text view. Then when I select one grid item I got below error (same exception).

My Attempt 2: Then I made the grid viwe to a simple list view by converting fragment to list fragment, so that I could find the issue. Now I'm getting the similar exception again.

Error I'm facing:

I tried: This suggestion and changed "extends AppCompatActivity" to "Extends Activity" but it seems not working for my case.

What I'm looking for: It is strange I cannot find where this casting gets failed. May I know any clue on how to fix this issue or how to trigger the failing point. I found several threads on this same exception but neither one of worked for me since I'm not using a custom adapter. I'm trying the simple version to find out the error.

Codes are as below where my selection fragment and the corresponding XML. I would appreciate any suggestions on this.
