## Design Credits

All design and inspiration credits belong to [Alejandro Ausejo](https://dribbble.com/shots/6251784-Navigation-Menu-Animation).

## Usage

- Create menu.xml under your res/menu/ folder
```xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

<item
android:id="@+id/item0"
android:title="@string/menu_dashboard"
android:icon="@drawable/ic_dashboard_white_24dp"/>

<item
android:id="@+id/item1"
android:title="@string/menu_leaderboard"
android:icon="@drawable/ic_multiline_chart_white_24dp"/>

<item
android:id="@+id/item2"
android:title="@string/menu_store"
android:icon="@drawable/ic_store_white_24dp"/>

<item
android:id="@+id/item3"
android:title="@string/menu_profile"
android:icon="@drawable/ic_person_outline_white_24dp"/>

</menu>
```

- Add view into your layout file
```xml
<me.ibrahimsn.lib.SmoothBottomBar
android:id="@+id/bottomBar"
android:layout_width="match_parent"
android:layout_height="70dp"
app:backgroundColor="@color/colorPrimary"
app:menu="@menu/menu_bottom"/>
```

## **Use SmoothBottomBar with [Navigation Components](https://developer.android.com/guide/navigation/).**

Coupled with the Navigation Component from the [Android Jetpack](https://developer.android.com/jetpack), SmoothBottomBar offers easier navigation within your application by designating navigation to the Navigation Component. This works best when using fragments, as the Navigation component helps to handle your fragment transactions.

- Setup Navigation Component i.e. Add dependenccy to your project, create a Navigation Graph etc.
- For each Fragment in your Navigation Graph, ensure that the Fragment's `id` is the same as the MenuItems in your Menu i.e res/menu/ folder
```xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

<item
android:id="@+id/first_fragment"
android:title="@string/menu_dashboard"
android:icon="@drawable/ic_dashboard_white_24dp"/>

<item
android:id="@+id/second_fragment"
android:title="@string/menu_leaderboard"
android:icon="@drawable/ic_multiline_chart_white_24dp"/>

<item
android:id="@+id/third_fragment"
android:title="@string/menu_store"
android:icon="@drawable/ic_store_white_24dp"/>

<item
android:id="@+id/fourth_fragment"
android:title="@string/menu_profile"
android:icon="@drawable/ic_person_outline_white_24dp"/>

</menu>
```

Navigation Graph i.e res/navigation/ folder
```xml
<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/nav_graph"
app:startDestination="@id/first_fragment">

<fragment
android:id="@+id/first_fragment"
android:name="[YOUR_NAMESPACE].FirstFragment"
android:label="First Fragment"
tools:layout="@layout/fragment_first" />
<fragment
android:id="@+id/second_fragment"
android:name="[YOUR_NAMESPACE].SecondFragment"
android:label="Second Fragment"
tools:layout="@layout/fragment_second" />
<fragment
android:id="@+id/third_fragment"
android:name="[YOUR_NAMESPACE].ThirdFragment"
android:label="Third Fragment"
tools:layout="@layout/fragment_third" />
<fragment
android:id="@+id/fourth_fragment"
android:name="[YOUR_NAMESPACE].FourthFragment"
android:label="Fourth Fragment"
tools:layout="@layout/fragment_fourth" />
</navigation>
```

- In your activity i.e `MainActivity`, override `onCreateOptionsMenu`, get a reference to your SmoothBottomBar and call `setupWithNavController()` which takes in a `Menu` and `NavController` on the SmoothBottomBar.
```csharp
public override bool OnCreateOptionsMenu(IMenu menu)
{
MenuInflater.Inflate(Resource.Menu.menu_bottom, menu);
if (menu != null)
{
BottomBar.SetupWithNavController(menu, NavController);
}

return true;
}
```
- You can also setup your `ActionBar` with the Navigation Component
```csharp
private NavController NavController;
private SmoothBottomBar BottomBar;
protected override void OnCreate(Bundle savedInstanceState)
{
try
{
base.OnCreate(savedInstanceState);
Xamarin.Essentials.Platform.Init(this, savedInstanceState);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.activity_main);
BottomBar = FindViewById<SmoothBottomBar>(Resource.Id.bottomBar);
NavController = Navigation.FindNavController(this, Resource.Id.main_fragment);
}
catch (System.Exception ex)
{

}
}
```

### Result:
