Using BubbleToggleView

BuggleToogleView is designed to work as a child component for the BubbleNavigationLinearView and BubbleNavigationConstraintView.
This view can be used independently

you may use it for your own implementation of NavigationBar
create new UI components
or simply use it as toggle view

attr	Description
bt_active	Sets to Active State
bt_colorActive	When in Active State, uses this color for the Icon and Title
bt_colorInctive	When in Inactive State, uses this color for the Icon and Title
bt_icon	Sets the Icon Drawable
bt_iconWidth	Updates the Icon Width
bt_iconHeigth	Updates the Icon Height
bt_title	Sets the Title Text
bt_titleSize	Updates the Tilte Text Size in sp
bt_shape	Sets the Background Drawable. Use TransitionDrawable to get fade in-out effect when toggling
bt_showShapeAlways	If true and using Normal drawable, background shape remains visible always
bt_shapeColor	Changes the tint color of the shape. N/A when using TransitionDrawable or showShapeAlways is true.
bt_duration	Sets time duration for toggle animation to complete in ms
bt_padding	Sets the internal padding in dp

Note: If you are using normal drawable and the shapes remain same of each Navigation Item, set the same drawable for each item, with different bt_shapeColor to get a similar effect. This might help in lower memory usage and performace improvements.
