If you’re looking to add a touch of dynamism to your Android application’s navigation interface, you’re in the right place! The Material Menu offers a morphing animation for menu buttons that can enhance user experience. This guide will walk you through the process of integrating the Material Menu into your Android app.

Understanding the Material Menu

Imagine the Material Menu as a fluid artist that transforms shapes into different forms. Similar to how an artist can blend colors and shapes to create a masterpiece, the Material Menu allows your menu icons to morph between states like a burger, arrow, and checkmark with animation. As it morphs, it keeps the user engaged and informed about the navigation state of the app.

Including the Material Menu in Your Project

To use the Material Menu, you’ll need to add it to your project by modifying your Groovy build file:

compile 'com.balysv.materialmenu:material-menu:2.0.0'

Using MaterialMenuDrawable in Your Toolbar

Follow these steps to implement the Material Menu Drawable:

• First, create a MaterialMenuDrawable instance in your activity.
• Set it as the toolbar’s navigation icon.
• Handle the navigation state changes with animations.

Here’s an example of how to do this:

private MaterialMenuDrawable materialMenu;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.toolbar);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override 
        public void onClick(View v) {
            // Handle your drawable state here
            materialMenu.animateState(newState);
        }
    });
    materialMenu = new MaterialMenuDrawable(this, Color.WHITE, Stroke.THIN);
    toolbar.setNavigationIcon(materialMenu);
}

Customizing MaterialMenuView

If you’d like to customize how the Material Menu looks, you can do so via XML attributes. Here are some attributes you can specify:

• app:mm_color: Color of the drawable
• app:mm_visible: Visibility of the drawable (boolean)
• app:mm_transformDuration: Duration for transformation animation (integer)
• app:mm_strokeWidth: Stroke width of icons (can only be 1, 2, or 3)
• app:mm_iconState: Set the initial state of the drawable (burger, arrow, x or check)

Working with the API

The API provides a number of methods to interact with the drawable states:

• animateIconState(IconState state): Morphs the drawable with animation.
• setIconState(IconState state): Changes the drawable state instantly.
• setVisible(boolean visible): Shows or hides the drawable.

Implementing Drawer Slide Interaction

To integrate the Material Menu with a navigation drawer, add a custom DrawerListener. Here’s how:

private DrawerLayout drawerLayout;
private boolean isDrawerOpened;
private MaterialMenuDrawable materialMenu;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    materialMenu = new MaterialMenuDrawable(this, Color.WHITE, Stroke.THIN);
    toolbar.setNavigationIcon(materialMenu);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawerLayout.setDrawerListener(new DrawerLayout.SimpleDrawerListener() {
        @Override
        public void onDrawerSlide(View drawerView, float slideOffset) {
            materialMenu.setTransformationOffset(
                MaterialMenuDrawable.AnimationState.BURGER_ARROW,
                isDrawerOpened ? 2 - slideOffset : slideOffset
            );
        }
        
        @Override
        public void onDrawerOpened(View drawerView) {
            isDrawerOpened = true;
        }
        
        @Override
        public void onDrawerClosed(View drawerView) {
            isDrawerOpened = false;
        }

        @Override
        public void onDrawerStateChanged(int newState) {
            if (newState == DrawerLayout.STATE_IDLE) {
                if (isDrawerOpened)
                    menu.setIconState(MaterialMenuDrawable.IconState.ARROW);
                else
                    menu.setIconState(MaterialMenuDrawable.IconState.BURGER);
            }
        }
    });
}

Troubleshooting

As you embark on this morphing menu journey, you may encounter a few bumps along the way. Here are some common issues and solutions:

• Issue: Material Menu not displaying correctly on the toolbar.
  Solution: Ensure that you have initialized the MaterialMenuDrawable correctly and assigned it to the toolbar’s navigation icon.
• Issue: Animation is not smooth or does not work.
  Solution: Check the transform duration in your XML attributes, as a very short duration may cause choppy animations.
