Usage

• Create menu.xml under your res/menu/ folder ```xml <?xml version=”1.0” encoding=”utf-8”?>

-   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.

Coupled with the Navigation Component from the Android 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”?>

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.

  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

  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:
