android:layout_height="wrap_content"
android:layout_marginBottom="380dp"
android:background="@color/white"
android:elevation="4dp"

| attr | Description |
|---|---|
| bnc_mode | Changes the display mode the child elements |
| - spread : equally distributes the child elements | |
| - packed : elements are packed with center gravity | |
| - inside : inside elements are equally distributed |
OR
<com.gauravk.bubblenavigation.BubbleNavigationLinearView

app:bt_titlePadding="@dimen/title_padding" />
<!-- Add more child items here - max upto 5 -->
</com.gauravk.bubblenavigation.BubbleNavigationLinearView>
Using BubbleToggleView
BubbleToggleView is designed to work as a child component for the BubbleNavigationLinearView and BubbleNavigationConstraintView.This view can be used independently for:
- Custom implementation of NavigationBar
- Creation of new UI components
- ToggleView
| 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 |
| bt_titlePadding | Sets the title padding in dp |
| bt_badgeText | Sets the text for the badge |
| bt_badgeTextSize | Sets the font size of the badge text |
| bt_badgeTextColor | Sets the text color of the badge |
| bt_badgeBackgroundColor | Sets the background color of the badge |
Note: Normal drawables may retain the shape of each Navigation item. Setting the same drawable for each item with different bt_shapeColor properties produces a similar effect while lowering memory usage and improving performance.
Activity/Fragment
In Java
bubbleNavigation.setNavigationChangeListener(new BubbleNavigationChangeListener() {
@Override
public void onNavigationChanged(View view, int position) {
//navigation changed, do something
}
});
Or in Kotlin

//navigation changed, do something here
}
| Method | Description |

void setCurrentActiveItem(int position) |
Changes the current active state for the navigation view |
void setTypeface(Typeface typeface) |
Updates the typeface of the text |
void setNavigationChangeListener(BubbleNavigationChangeListener listener) |
