Question

I have a AppCompatActivity that controls replacing many fragments. Here is my layout for it.

activity_main.xml

Answer 1

I have used @JasonWyatt's solution and added DragCallback to behavior class to prevent touch and drag CollapsingToolbarLayout to expand it

private void setDragCallback() {
    setDragCallback(new DragCallback() {
        @Override
        public boolean canDrag(@NonNull AppBarLayout appBarLayout) {
            return mEnabled;
        }
    });
}
