Usage

Xml file：

The root layout must be CoordinatorLayout，which is similar to FrameLayout

    <android.support.design.widget.CoordinatorLayout
        ...>
        <FloatingActionButton
            ...
            app:layout_behavior="@string/fab_vertical_behavior/>
    </android.support.design.widget.CoordinatorLayout>

Set different layout_behavior in xml file according to different view.

Custom properties(All have default values)：

    CommonBehavior behavior = CommonBehavior.from(mFloatingActionButton)；

    behavior.show();//show the view
    behavior.hide();//hide

    behavior.setMinScrollY(20)
    behavior.setScrollYDistance(100)
    behavior.setDuration(1000)
    behavior.setInterpolator(new LinearOutSlowInInterpolator());

Tips

1、Because the root layout is CoordinatorLayout, the toolbar may cover the item at the top of the recyclerView when used, and the bottom bar may also cover the bottom item. You can add a placeholder such as itemDecoration to the recyclerView, or a placeholder view at the top. If the situation is relatively simple, you can simply set padding, margin and so on. I have dealt with this kind of situation in the demo simply.

2、If the elevation of the floatingActionButton is greater than that of the bottomBar, the animation of the floatingActionButton will cover the top of the bottomBar, and vice versa.
