Answer 1

Tried using android.widget.PopupMenu instead of android.support.v7.widget.PopupMenu and Voila, it works. So is it a bug in Support library. Can great developers out here confirm the same?

requestRectangleOnScreennot work for me, in my case, requestRectangleOnScreennot called, when show popupMenu. my solution is override requestChildRectangleOnScreen, and reture false, work well.

public class PopupAncorRecyclerViewPager extends RecyclerView {
        @Override
    public boolean requestChildRectangleOnScreen(View child, Rect rect, boolean immediate) {
        return false;
    }
}

You can have your AnchorView override requestRectangleOnScreen() and return false. This will prevent any parent ScrollView from scrolling.

So, in your case, imgBtnOverflow would be a custom ImageButton, like so:

/**
 * A custom {@link ImageButton} which prevents parent ScrollView scrolling when used as the
 * anchor for a {@link android.support.v7.widget.PopupMenu}
 */
public class NonScrollImageButton extends ImageButton {

    public NonScrollImageButton(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean requestRectangleOnScreen(Rect rectangle, boolean immediate) {
        return false;
    }
}

I have same problem, and I use this way:

mLayoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.HORIZONTAL, false) {
            @Override
            public boolean requestChildRectangleOnScreen(RecyclerView parent, View child, Rect rect, boolean immediate) {
                return false;
            }
        };
mRecyclerView.setLayoutManager(mLayoutManager);

RecyclerView user layoutmanager to manage layout, so I think change layoutmanger behaver is the bettor solution.
