FanMenu

A simple widget that can be used to display menu's which can be animated in and out. The menu's can be animated in from behind a button like a FloatingActionButton to give an effect of a submenu or can be placed on the screen to work as menus.

Features

• Show as many menu items as you like, with or without icons.
• Icons can be changed when selected.
• Colors, text and icons can be specified in the xml.
• If a background color is set, this fades in/out when the menu opens/closes.
• The menu can be movable or fixed.
• Menu can reset if moved beyond a certain boundary.

Adding it to your project

compile 'com.bcgdv.asia.lib:fanmenu:1.4'

Usage

The menus needs to be configured in the XML.

<com.bcgdv.asia.lib.fanmenu.FanMenuButtons
    android:background="#CCFFFFFF"
    android:id="@+id/myFABSubmenu"
    android:layout_alignBaseline="@+id/myFAB"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textColor="@android:color/white"

    android:paddingBottom="@dimen/fab_submenu_margin_bottom"
    android:textSize="14sp"
    app:fanMenuLabels="@array/fan_labels"
    app:fanButtonColors="@array/button_colors"
    app:fanLeftDrawable="@array/button_icons"
    app:fanRememberMovedPosition="true"
    app:fanMinBounceBackAngle="-30"
    app:fanMaxBounceBackAngle="50"
    android:visibility="gone" />

Labels need to be defined as string-array resource.

<string name="menu_top_stories">Top Stories</string>

    <item>@string/menu_sports</item>
    <item>@string/menu_tech</item>
</string-array>

Button colors need to be defined as an integer-array resource.

<color name="red_1">#C2185B</color>
<color name="red_2">#E91E63</color>
<color name="red_3">#F44336</color>
<color name="red_4">#FF5722</color>
<integer-array name="button_colors">

    <item>@color/red_2</item>
    <item>@color/red_3</item>
    <item>@color/red_4</item>

Callbacks

final FanMenuButtons sub = (FanMenuButtons) findViewById(R.id.myFABSubmenu);
if (sub != null) {
    sub.setOnFanButtonClickListener(new FanMenuButtons.OnFanClickListener() {
        @Override
        public void onFanButtonClicked(int index) {
        }
    });

	sub.setOnFanAnimationListener(new FanMenuButtons.OnFanAnimationListener() {
		@Override
		public void onAnimateInStarted() {
		}

		@Override
		public void onAnimateOutStarted() {
		}

		@Override
		public void onAnimateInFinished() {
		}

		@Override
		public void onAnimateOutFinished() {
