### Activity/Fragment
```java
AHBottomNavigation bottomNavigation = (AHBottomNavigation) findViewById(R.id.bottom_navigation);

// Create items
AHBottomNavigationItem item1 = new AHBottomNavigationItem(R.string.tab_1, R.drawable.ic_maps_place, R.color.color_tab_1);
AHBottomNavigationItem item2 = new AHBottomNavigationItem(R.string.tab_2, R.drawable.ic_maps_local_bar, R.color.color_tab_2);
AHBottomNavigationItem item3 = new AHBottomNavigationItem(R.string.tab_3, R.drawable.ic_maps_local_restaurant, R.color.color_tab_3);

// Add items
bottomNavigation.addItem(item1);
bottomNavigation.addItem(item2);
bottomNavigation.addItem(item3);

// Set background color
bottomNavigation.setDefaultBackgroundColor(Color.parseColor("#FEFEFE"));

// Disable the translation inside the CoordinatorLayout
bottomNavigation.setBehaviorTranslationEnabled(false);

// Change colors
bottomNavigation.setAccentColor(Color.parseColor("#F63D2B"));
bottomNavigation.setInactiveColor(Color.parseColor("#747474"));

// Force to tint the drawable (useful for font with icon for example)

// Use colored navigation with circle reveal effect
bottomNavigation.setColored(true);

// Add or remove notification for each item
bottomNavigation.setNotification("4", 1);
bottomNavigation.setNotification("", 1);

// Set listener
bottomNavigation.setOnTabSelectedListener(new AHBottomNavigation.OnTabSelectedListener() {
	@Override
	public boolean onTabSelected(int position, boolean wasSelected) {
		// Do something cool here...
        return true;
	}
