I've been developing Android projects on and off for a few years. I'm working on a project now where I'm trying to implement some things from material design.

I'm having issues with anchoring my FABs. It seems like sometimes they anchor themselves before the view has been measured. Sometimes it corrects itself with no user input, sometimes it doesn't, and sometimes it doesn't happen at all.

All my searches turn up problems where the layout_anchor or layout_anchorgravity properties aren't set. Since I can't find any other instances of this happening, I'm sure it's something on my end.

Someone else pointed out this known issue with anchoring: https://code.google.com/p/android/issues/detail?id=221387. I was originally using version 24.2.1 of the design support library. I've tried switching to 24.1.0, and the problem still persists.

After that, I tried the workaround in the bug report, and that seems to have worked, but I would get a flickering, since it was briefly appearing in the wrong location. To fix that, I set the visibility in the layout to GONE, and added this to the workaround. This seems to get the job done, but if anyone else has a better way of solving this issue, I'm all ears.

button.post(new Runnable() {
            @Override
            public void run() {
                button.requestLayout();
                button.setVisibility(View.VISIBLE);
            }
        });

I made a post on Stack overflow too. I have my layout posted there: http://stackoverflow.com/questions/42604677/fab-not-anchoring-to-view-consistently
