Morphing Android menu, back, dismiss and check buttons

Demo Image

Demo Drawer

Including in your project

Groovy

Maven Central

Versions up to 2.0 (deprecated)

See [README][1] for setting up older versions of the library.

Usage

MaterialMenuDrawable

Use it as a standalone drawable in your Toolbar:

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);
}
Java

MaterialMenuView

A plain old View that draws the icon and provides an API to manipulate its state. You can embed it
in any layout including a Toolbar.

Customisation is also available through xml attributes:

app:mm_color="color"               // Color of drawable
app:mm_visible="boolean"           // Visible
app:mm_transformDuration="integer" // Transformation animation duration
app:mm_scale="integer"             // Scale factor of drawable
app:mm_strokeWidth="integer"       // Stroke width of icons (can only be 1, 2 or 3)
app:mm_rtlEnabled="boolean"        // Enabled RTL layout support (flips all drawables)
app:mm_iconState="enum"            // Set the intial state of the drawable (burger, arrow, x or check)
XML

API

There are four icon states:

BURGER, ARROW, X, CHECK
Java

To morph the drawable state

MaterialMenu.animateIconState(IconState state)
Java

To change the drawable state without animation

MaterialMenu.setIconState(IconState state)
Java

To animate the drawable manually (i.e. on navigation drawer slide):

MaterialMenu.setTransformationOffset(AnimationState state, float value)
Java

To hide or show the drawable:

MaterialMenu.setVisible(boolean visible)
Java

where AnimationState is one of BURGER_ARROW, BURGER_X, ARROW_X, ARROW_CHECK, BURGER_CHECK, X_CHECK
and value is between 0 and 2

Note: The icon state is resolved by current offset value. Make sure you use offset between 0 and 1 for forward animation and 1 and 2 for backwards to correctly save icon state on activity recreation.

Implement MaterialMenu into your ActionBar as described above and add a custom DrawerListener:

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);
                }
            }
        }
    });
}
