Error when trying to use FAB Speed Dial in a Coordinator Layout

[mezpahlan]

I'm getting the following error when trying to use FAB Speed Dial in a Coordinator Layout

Default behavior class io.github.yavski.fabspeeddial.FabSpeedDialBehaviour could not be instantiated. Did you forget a default constructor?
java.lang.InstantiationException: class io.github.yavski.fabspeeddial.FabSpeedDialBehaviour has no zero argument constructor

Possibly related to #29 ?

I've added the following to FabSpeedDialBehaviour.javaand it seems to fix this.

public FabSpeedDialBehaviour() { }

Do you need a PR for this? Happy to provide one if so.

Also solves #11 for me too!

@mezpahlan Thanks for reporting it - how do you reproduce it? Yes it seems to be a regression from #29, I will add back the no-arg constructor tonight.

@yavski No worries.

Steps to reprodcue for #11 :

1. Follow set up instructions for library
2. Place FAB-Speed-Dial inside coordinator layout

Expected result:

Preview is rendered without errors

Actual result:

Error message appears in preview mode (although app works fine when running)

Steps to reproduce for #32 (this one):

1. Follow set up instructions for library
2. Place FAB-Speed-Dial inside coordinator layout
3. Run app up in emulator (debug mode for app). I used a Nexus 5X emulator preset from Android Studio, no special tweaks running API 22...... but I don't think that matters.
4. Observe Logcat output messages

Expected result:

No error messages in Logcat output window

Actual result:

Error message in Logcat output window relating to missing default constructor.

Simply adding it back in gives me the desired result (i.e. no errors in preview mode and no Logcat errors). However, I just wanted to be sure that was absolutely the correct thing to do.

Anyways, good luck! Great library BTW.
