java.lang.IllegalArgumentException: parameter must be a descendant of this view

Question

I'm getting multiple crashes with this message parameter must be a descendant of this view from various Redmi devices. I have read similar questions on stackoverflow but I couldn't understand their solutions. As these logs don't include the activity or function names, I'm confused about where to start.

My app has lot of activities and fragments. How can I find the component causing this crash?

I'm not able to reproduce this crash. Any thoughts?

The error is being thrown by the following code in ViewGroup.java. See here.

/**
 * Helper method that offsets a rect either from parent to descendant or
 * descendant to parent.
 */
void offsetRectBetweenParentAndChild(View descendant, Rect rect,
        boolean offsetFromChildToParent, boolean clipToBounds) {

...

    // now that we are up to this view, need to offset one more time
    // to get into our coordinate space
    if (theParent == this) {
        if (offsetFromChildToParent) {
            rect.offset(descendant.mLeft - descendant.mScrollX,
                    descendant.mTop - descendant.mScrollY);
        } else {
            rect.offset(descendant.mScrollX - descendant.mLeft,
                    descendant.mScrollY - descendant.mTop);
        }
    } else {
        throw new IllegalArgumentException("parameter must be a descendant of this view");
    }
}
...

From another question related to the same error message, it looks like there was an attempt to add a view to two ViewGroups. The "parameter" in the message is the "descendant" View and "this view" is the ViewGroup.

I will guess that you are doing something similar, although there is not enough information to immediately identify the source of the problem. A view can only have one parent.

Does this happen when we inflate the same layout.xml for different listViews in a viewPager? – Sujith S Manjavana Oct 07 '22 at 05:38
If you inflate the view twice then no. If you inflate the view once and use it twice then yes; you could see that problem. – Cheticamp Oct 07 '22 at 12:40
I have a ViewPager with 3 fragments. Each fragment contains a ListView that inflates the same layout xml for list item. – Sujith S Manjavana Oct 07 '22 at 12:52
From the stack traces you posted, it looks like the problem is happening during layout of some set of views. From what is printed it looks like the layout has a _LinearLayout_, a _RecyclerView_ and a _ViewPager_ since classes related to these types of views are mentioned. Hopefully, you just have one layout that fits this description. It may be helpful if you could identify the related code and post it and the associated layout(s). – Cheticamp Jan 02 '23 at 01:08
Stack traces 2-5 are the same error. At least the calling stack is the same with just different line number probably due to different APIs. The first error may be related, but it may not be the same error as the others since its stack trace is so different. – Cheticamp Jan 02 '23 at 17:37
