Including in your project

// stock actionBar
compile 'com.balysv.materialmenu:material-menu:1.5.5'

// Toolbar and ActionBarCompat-v22 (includes support-v7:22.0.x)
compile 'com.balysv.materialmenu:material-menu-toolbar:1.5.5'

// actionBarCompat-v20 (up to support-v7:20.0.0 - does not support Toolbar)
compile 'com.balysv.materialmenu:material-menu-abc:1.5.5'

// actionBarSherlock
compile 'com.balysv.materialmenu:material-menu-abs:1.5.5'

Usage

The library provides two wrappers of MaterialMenuDrawable that eases implementation into the ActionBar, NavigationDrawer slide interaction or into any other custom layout.

MaterialMenuView

A plain old View that draws the icon and provides an API to manipulate its state.

Customisation is also available through 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)

MaterialMenuIcon

A POJO that initializes the drawable and replaces the ActionBar icon.

Jump to instructions for :

API

There are four icon states:

BURGER, ARROW, X, CHECK

To morph the drawable state

MaterialMenu.animateState(IconState state)

To change the drawable state without animation

MaterialMenu.setState(IconState state)

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

MaterialMenu.setTransformationOffset(AnimationState state, float value)

To hide or show the drawable:

MaterialMenu.setVisible(boolean visible)

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 current implementation resolves its state 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.

Customisation

// change color
MaterialMenu.setColor(int color)

// change icon visibility
MaterialMenu.setVisible(boolean visible)

// change transformation animation duration
MaterialMenu.setTransformationDuration(int duration)

// change transformation interpolator
MaterialMenu.setInterpolator(Interpolator interpolator)

// set RTL layout support
MaterialMenu.setRTLEnabled(boolean enabled)

Action Bar

Use as Action Bar icon (stock, Compat or Sherlock)

Depending on the ActionBar you use, use one of the following classes: MaterialMenuIcon, MaterialMenuIconCompat or MaterialMenuIconSherlock.

In your Activity add the following:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    materialMenu = new MaterialMenuIcon(this, Color.WHITE, Stroke.THIN);
}

protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    materialMenu.syncState(savedInstanceState);
}

protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    materialMenu.onSaveInstanceState(outState);
}

public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getId() == android.R.id.home) {
        // Handle your drawable state here
        materialMenu.animateState(newState);
    }
}

Use in Toolbar

Use it as a standalone drawable. Note: you have to handle icon state yourself:

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);
}

OR

Use MaterialMenuIconToolbar which handles saved state:

private MaterialMenuIconToolbar materialMenu;

@Override
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 MaterialMenuIconToolbar(this, Color.WHITE, Stroke.THIN) {
        @Override public int getToolbarViewId() {
            return R.id.toolbar;
        }
    };
}

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    materialMenu.syncState(savedInstanceState);
}

@Override protected void onSaveInstanceState(Bundle outState) {
    materialMenu.onSaveInstanceState(outState);
    super.onSaveInstanceState(outState);
}

Use in custom Action Bar view

Simply add MaterialMenuView in your custom layout and register an OnClickListener to do the transformations.

See source of Demo for details

NavigationDrawer slide interaction

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

private DrawerLayout drawerLayout;
private boolean      isDrawerOpened;
private MaterialMenuIcon materialMenu;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    materialMenu = new MaterialMenuIcon(this, Color.WHITE, Stroke.THIN); // or retrieve from your custom view, etc
    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.setState(MaterialMenuDrawable.IconState.ARROW)
                else menu.setState(MaterialMenuDrawable.IconState.BURGER)
            }
        }
    });
}


@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    isDrawerOpened = drawerLayout.isDrawerOpen(Gravity.START); // or END, LEFT, RIGHT
    materialMenu.syncState(savedInstanceState);
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    materialMenu.onSaveInstanceState(outState);
}
