Any way to hide FAB(floating action button) via xml?

Question

Is there any way to hide/disable Floating action button in Android via xml file without editing Java file? Just want to hide a share button in an app and I tried editing related xml file. Tried to set invisible, gone etc but none of these works. Button is still there. At least to reduce the size of button to almost invisible? I think we cant change fab:fab_size="normal" to other values. So that too didn't work. So is there any way??

yes. already tried visibility=gone, visibility=invisible but it's not working — user3548321, Apr 11 '16 at 06:11
So this means, we can't hide it via xml only if app:layout_anchor attribute is there. Right? no other way to hide via xml? — user3548321, Apr 11 '16 at 06:13
No. deleting will not work. I tried but another activity important activity will not work if i delete it. — user3548321, Apr 11 '16 at 06:18
@shree krishana: I didn't tried that yet. i was asking, is there an way to do this without touching java. only via xml — user3548321, Apr 11 '16 at 06:20
Thanks everybody. i was aware of the app:layout_anchor issue before i posted the question, but my question was about hiding it via xml without touching java code. I think it's not possible. Anyway I'm keeping this question open. Let's see if anybody have some tricks to do this via xml only. Thanks a lot for replies. — user3548321, Apr 12 '16 at 01:17

Discussed already on this issue, Main reason is

If you set a set a FloatingActionButton to be anchored, you lose control of the visibility.

So you have to remove layout_anchor attribute from FloatingActionButton first.

You have to use java somewhere at the point. Cant do it with only with XML The trick given is

To wrap your FAB in a coordinator layout that is not the root of your entire layout, but as a sort of overlay to everything. From there you can manage the visibility of the coordinator layout initially so it's invisible, then make it visible when you call fab.show().
