Basic implemetation

To add the BottomNavigationView follow these steps:

Add in your build.gradle the dependency:

compile ‘com.android.support:design:25.1.0’

Add the BottomNavigationView in your layout:

<android.support.design.widget.BottomNavigationView
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:menu="@menu/bottom_navigation_menu"/>

Create the menu to populate the view:

<!-- res/menu/bottom_navigation_menu.xml -->

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/my_action1"
        android:enabled="true"
        android:icon="@drawable/my_drawable"
        android:title="@string/text"
        app:showAsAction="ifRoom" />
    ....
</menu>

Attach a listener for the click events:

//Get the view
BottomNavigationView bottomNavigationView = (BottomNavigationView)
                findViewById(R.id.bottom_navigation);
//Attach the listener
bottomNavigationView.setOnNavigationItemSelectedListener(
        new BottomNavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                switch (item.getItemId()) {

                    case R.id.my_action1:
                        //Do something...
                        break;

                    //...
                }
                return true;//returning false disables the Navigation bar animations
            }
        });
