Material Menu

Morphing Android menu, back, dismiss and check buttons

Including in your project

The library is available on Maven Central

dependencies {
    compile 'com.balysv:material-menu:1.1.0'
}

Usage

Generally, you should use MaterialMenuDrawable as a standalone drawable in your custom views, etc.

The library provides two wrappers that might ease implementation:

MaterialMenuView

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

Customisation is also available through attributes:

app:color="color"               // Color of drawable
app:transformDuration="integer" // Transformation animation duration
app:pressedDuration="integer"   // Pressed circle animation duration
app:scale="integer"             // Scale factor of drawable

MaterialMenuIcon

A POJO that initializes the drawable and replaces the ActionBar icon. See usage in ActionBar below

API

There are four icon states:

BURGER, ARROW, X, CHECK

To morph the drawable state with a pressed circle animation

MaterialMenu.animatePressedState(IconState state)

To morph the drawable state without a pressed circle animation

MaterialMenu.animateState(IconState state)    

To change the drawable state without animation

MaterialMenu.setState(IconState state)

Customisation

// change color
MaterialMenu.setColor(int color)

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

// change pressed animation duration
MaterialMenu.setPressedDuration(int duration)

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

Action Bar

Use as Action Bar icon (stock only)

In your Activity add the following:

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

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

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

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

In order to use the new Material circle pressed state, you have to disable ActionBar item backgrounds in your theme and re-enable it for other menu icons

<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
    <item name="android:actionBarItemBackground">@null</item>
    <item name="android:actionButtonStyle">@style/ActionButtonStyle</item>
    <item name="android:actionOverflowButtonStyle">@style/OverflowButtonStyle</item>
</style>

<style name="ActionButtonStyle" parent="android:Widget.Holo.ActionButton">
    <item name="android:background">@drawable/action_bar_item_background</item>
</style>

<style name="OverflowButtonStyle" parent="android:Widget.Holo.ActionButton.Overflow">
    <item name="android:background">@drawable/action_bar_item_background</item>
</style>

Otherwise, to disable circle pressed state use

MaterialMenu.setNeverDrawTouch(true)

Use in custom Action Bar view

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