Usage

Create Menu File

Create a menu file below resource folder. Right click to res then New > Android Resource File, type a file name and make sure you choose ResourceType as Menu. Here is a sample menu file. You can add android:checked="true" if you want that menu item active at the begin

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/action_home"
        android:icon="@drawable/ic_home_black_24dp"
        android:checked="true"
        android:title="@string/home" />
    <item
        android:id="@+id/action_browse"
        android:icon="@drawable/ic_speaker_group_black_24dp"
        android:title="@string/browse" />
    <item
        android:id="@+id/action_search"
        android:icon="@drawable/ic_search_black_24dp"
        android:title="@string/search" />
    <item
        android:id="@+id/action_radio"
        android:icon="@drawable/ic_radio_black_24dp"
        android:title="@string/radio" />
    <item
        android:id="@+id/action_library"
        android:icon="@drawable/ic_library_music_black_24dp"
        android:title="@string/your_library" />
</menu>

Bottomify to Layout

Add Bottomify in your layout xml

    <com.volcaniccoder.bottomify.BottomifyNavigationView
        android:id="@+id/bottomify_nav"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/bottomifyBackgroundColor"
        android:orientation="horizontal"
        app:menu="@menu/navigation_items"
        app:active_color="@color/bottomifyActiveColor"
        app:passive_color="@color/bottomifyPassiveColor"
        app:pressed_color="@color/bottomifyPressedColor"
        app:item_text_size="10sp"
        app:item_padding="4dp"
        app:animation_duration="300"
        app:scale_percent="5" />
}

Here are some comments about what xml attributes do

       /**
         * app:menu -> Provide a menu for bottom view items
         * app:active_color -> The color of the active and choosen menu item
         * app:passive_color -> The color of non active menu items
         * app:pressed_color -> The color when you press on menu item
         * app:item_text_size -> The size of the menu item text
         * app:item_padding -> The padding of the menu item
         * app:animation_duration="300" -> The amount of time of the click animation
         * app:scale_percent="5" -> The percent of downsizing animation. If its 50 view will downsize to half and full again
         */

Code Side

If you want to be notified about the change of navigation item you can implement OnNavigationItemChangeListener

        val bottomify = findViewById<BottomifyNavigationView>(R.id.bottomify_nav)
        bottomify.setOnNavigationItemChangedListener(object : OnNavigationItemChangeListener {
            override fun onNavigationItemChanged(navigationItem: BottomifyNavigationView.NavigationItem) {
                Toast.makeText(this@MainActivity,
                        "Selected item at index ${navigationItem.position}",
                        Toast.LENGTH_SHORT).show()
            }
        })

If you want to set active item not by a click but programmatically

        bottomify.setActiveNavigationIndex(2)
