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.

Activity/Fragment

In Java

  bubbleNavigation.setNavigationChangeListener(new BubbleNavigationChangeListener() {
