Answer 1

My problem was very similar to @Artem I tried many fix but none of them worked for me. @Jraco11's answer is correct when you use AppBarLayout. @johnrao07 not worked for me. But I found a perfect solution for this problem when we use Toolbar.

To hide Toolbar programatically

if (toolbar.getParent() instanceof AppBarLayout){
                    ((AppBarLayout)toolbar.getParent()).setExpanded(false,true);
                }

To show Toolbar programatically

if (toolbar.getParent() instanceof AppBarLayout){
                        ((AppBarLayout)toolbar.getParent()).setExpanded(true,true);
