Chip Navigation Bar

A navigation bar widget inspired on Google Bottom Navigation mixed with Chips component.

Usage

<!-- bottom_menu.xml -->
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/home"
        android:icon="@drawable/ic_home"
        android:title="Home"
        app:cnb_iconColor="@color/home"/>
    <item
        android:id="@+id/activity"
        android:icon="@drawable/ic_activity"
        android:title="Activity"
        app:cnb_iconColor="@color/activity"/>
    <item
        android:id="@+id/favorites"
        android:icon="@drawable/ic_heart"
        android:title="Favorites"
        app:cnb_iconColor="@color/favorites" />
    <item
        android:id="@+id/settings"
        android:icon="@drawable/ic_settings"
        android:title="Settings"
        app:cnb_iconColor="@color/settings" />
</menu>

<!-- layout.xml -->
<com.ismaeldivita.chipnavigation.ChipNavigationBar
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:background="@color/white"
    app:cnb_menuResource="@menu/bottom_menu" />

Vertical orientation

ChipNavigationBar supports a vertical orientation mode. This is very useful for
tablets or devices with large screens.

Just add the attribute cnb_orientationMode to your xml:

<com.ismaeldivita.chipnavigation.ChipNavigationBar
    android:id="@+id/bottom_menu"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    app:cnb_menuResource="@menu/test"
    app:cnb_orientationMode="vertical" />

... or programmatically call the method setMenuOrientation before inflate the menu:

menu.setMenuOrientation(MenuOrientation.VERTICAL)
menu.setMenuResource(R.menu.my_menu)

Note: The view exposes methods to expand and collapse the menu but we don't provide the implementation for the toggle button. Check the sample for a basic implementation.
