NullPointerException when start activity about android-floating-action-button

[chalup]

It's probably related to the way I set up animations, I'll take a closer look at this.

As a workaround you can add expand() call to the message queue instead of calling it directly:

    final FloatingActionsMenu menu = (FloatingActionsMenu) findViewById(R.id.multiple_actions);
    menu.post(new Runnable() {
      @Override
      public void run() {
        menu.expand();
      }
    });

very nice, thanks. Just one more question, I want to known when user click on FloatingActionsMenu. I try menu.setOnClickListener{...} seem not working, can you check it ?

[chalup]

It won't work, because internally menu creates a FloatingActionButton, which has it's own onClickListener and calls FloatingActionsMenu.toggle on clicking.

Can you explain in details what are you trying to achieve, i.e. what would you put in your onClickListener? I'm asking, because I wonder what will be the optimal API (there are at least few options).

I just want hide FloatAction menu when the menu is collapse. I'll change another thing. Your FloatActionMenu just expande a direction (left, right, top, bottom), right? So, I want to expande two direction TOP and LEFT or TOP and RIGHT. What solution for me?

[chalup]

I'd say you need some kind of onCollapsed/onExpanded callbacks, but I'm not
sure if they should trigger before or after the animation. Please note that
this feature is not a priority for me, so if you need it urgently,
implement it yourself (and obviously send me a pull request).

The other request, if I understand it correctly, is about menu expanding to
a grid of buttons. That's not going to happen, at least not in a
foreseeable future.

I'll try it. So, how we are making border (and set color for that border if can) for FloatActionButton ?

Borders for FAB is not something I intend to work on.

I know it has been a long time since this was asked, but I can answer the second question.
You can get the menu button to set an onclick to it via:

FloatingActionButton FAB = (FloatingActionButton) findViewById(R.id.fab_expand_menu_button);

@NathanBFS I recommend using OnFloatingActionsMenuUpdateListener if possible.
