ExpandableButtonMenu

ExpandableButtonMenu is an Android library which implements an expandable button that can be used as a substitute of a fixed size menu. It is a Foursquare like button that expands into three buttons.

Including in your project

The library is available on Maven Central

dependencies {
    compile 'co.lemonlabs:expandable-button-menu:1.0.0'
}

Usage

The library supports Android 2.3+.

Just include this view to your root layout (current only RelativeLayout is supported):

<lt.lemonlabs.android.expandablebuttonmenu.ExpandableMenuOverlay
    android:id="@+id/button_menu"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:src="@drawable/circle_home"
/>

Custom attributes can be used for easy customization. Add this to your layout declaration:

xmlns:ebm="http://schemas.android.com/apk/res-auto"

and you can use these attributes

ebm:dimAmount="0.8"        // Screen dim amount when menu is expanded
ebm:mainButtonSize="0.25"  // Main button size in % of screen height
ebm:otherButtonSize="0.22" // Expanded menu button size in % of screen height
ebm:distanceY="0.17"       // Distance between expanded and collapsed button in screen % of screen height
ebm:distanceX="0.28"       // Distance between expanded button in % of screen width
ebm:bottomPad="0.02"       // Button padding in % of screen height

// Button drawable and text resources
ebm:closeButtonSrc="@drawable/circle_close"
ebm:leftButtonSrc="@drawable/circle_1"
ebm:midButtonSrc="@drawable/circle_2"
ebm:rightButtonSrc="@drawable/circle_3"
ebm:leftButtonText="@string/action_left"
ebm:midButtonText="@string/action_mid"
ebm:rightButtonText="@string/action_right"

In your activity/fragment add the callbacks:

menuOverlay = (ExpandableMenuOverlay) findViewById(R.id.button_menu);
menuOverlay.setOnMenuButtonClickListener(new ExpandableButtonMenu.OnMenuButtonClick() {
    @Override
    public void onClick(ExpandableButtonMenu.MenuButton action) {
        switch (action) {
            case MID:
            // do stuff and dismiss
            menuOverlay.getButtonMenu().toggle();
            break;
            case LEFT:
            // do stuff
            break;
            case RIGHT:
            // do stuff
            break;
        }
    }
});
