Simple material-style flyout menus for Android. There are many flyout type menus for Android, but this one is mine.

compile 'org.zakariya.flyoutmenus:flyoutmenu:0.5.3'
  • minSdkVersion: 14 Note: when running on SDK less than 18, hardware rendering is disabled. This means that button shadows are clipped. To work around this, add a bit of padding to the view.

FlyoutMenuView attributes (all have fm prefix) are:

// the size of the button
<attr name="fmButtonSize" format="dimension"/>

// the background color of the trigger button
<attr name="fmButtonBackgroundColor" format="color"/>

// the background color of the menu
<attr name="fmMenuBackgroundColor" format="color"/>

// the color drawn behind the selected menu item
<attr name="fmSelectedItemBackgroundColor" format="color"/>

// width of items in the menu
<attr name="fmItemWidth" format="dimension"/>

// height of items in the menu
<attr name="fmItemHeight" format="dimension"/>

// margin around items in the menu
<attr name="fmItemMargin" format="dimension"/>

// menu anchoring position (see below)
<attr name="fmMenuAnchor" format="string"/>

// margin around the menu - menu will be positioned this far away from the button, but 
// will also use this to respect screen edges
<attr name="fmMenuMargin" format="dimension"/>

// if provided, the trigger button will use this as a drawable
<attr name="fmButtonSrc" format="reference"/>

// elevation for the trigger button. if 0, no shadow is drawn
<attr name="fmButtonElevation" format="dimension"/>

// elevation for the menu. if 0, no shadow is drawn
<attr name="fmMenuElevation" format="dimension"/>

// if true, a shield (like for dialogs) is drawn behind the menu
<attr name="fmShieldVisible" format="boolean"/>

// color of shield drawn behind menu, if shieldVisible == true
<attr name="fmShieldColor" format="color"/>

// if true, menu operates in "tap to open", "tap to select and dismiss" mode
<attr name="fmDialogMode" format="boolean"/>

The fmMenuAnchor attribute takes the following values:

  • top : menu attached above the button
  • right | end : menu attached to right of button
  • bottom : menu attached beneath button
  • left | start : menu attached to left of button
  • center : menu centered on top of button


To use a FlyoutMenuView, you must provide a FlyoutMenuView.Adapter (which provides FlyoutMenuView.MenuItem instances) and a FlyoutMenuView.Layout which describes how to position the items in the menu.

You must also provide a subclass of FlyoutMenuView.MenuItem to render your items. You may also subclass FlyoutMenuView.ButtonRenderer to render your trigger button, if you don't want to assign a Drawable.

Here's an example implementation of FlyoutMenuView.MenuItem and FlyoutmenuView.ButtonRenderer which draws a simple unicode character. I use it in the demo app to render emoji.

public class EmojiFlyoutMenu {

 static String getEmojiByUnicode(int unicode){
  return new String(Character.toChars(unicode));

 public static class MenuItem extends FlyoutMenuView.MenuItem {

  int emojiCode;
  String emojiString;
  TextPaint textPaint;

  public MenuItem(int id, int emojiCode, float size, @ColorInt int color) {
   this.emojiCode = emojiCode;
   this.emojiString = getEmojiByUnicode(emojiCode);

   textPaint = new TextPaint();

  public int getEmojiCode() {
   return emojiCode;

  public void onDraw(Canvas canvas, RectF bounds, float degreeSelected) {
   canvas.drawText(emojiString, bounds.centerX(), bounds.centerY() - ((textPaint.descent() + textPaint.ascent()) / 2), textPaint);

 public static class ButtonRenderer extends FlyoutMenuView.ButtonRenderer {

  int emojiCode;
  String emojiString;
  Paint paint;
  TextPaint textPaint;

  public ButtonRenderer(int emojiCode, float size, @ColorInt int color) {


   paint = new Paint();

   textPaint = new TextPaint();

  public int getEmojiCode() {
   return emojiCode;

  public void setEmojiCode(int emojiCode) {
   this.emojiCode = emojiCode;
   this.emojiString = getEmojiByUnicode(this.emojiCode);

  public void onDrawButtonContent(Canvas canvas, RectF buttonBounds, @ColorInt int buttonColor, float alpha) {
   textPaint.setAlpha((int) (alpha * 255f));
   canvas.drawText(emojiString, buttonBounds.centerX(), buttonBounds.centerY() - ((textPaint.descent() + textPaint.ascent()) / 2), textPaint);

To use the above:

FlyoutMenuView smileyFlyoutMenu = findViewById(; 

int[] emojiCodes = {
  0x1F60D, //smiling face heart shaped eyes
  0x1F605, // smiling face with open mouth and cold sweat
  0x1F60A, // smiling face
  0x1F613, // face with cold sweat
  0x1F61E, // disappointed face
  0x1F620, // angry face
  0x1F62D, // loudly crying face
  0x1F4A9, // pile of poo

@ColorInt int color = ContextCompat.getColor(this, R.color.smileyMenuCharColor);
float fontSizeInMenu = getResources().getDimension(R.dimen.smiley_menu_item_size) * 0.5f;
float fontSizeInButton = getResources().getDimension(R.dimen.flyout_menu_button_size) * 0.5f;

// build a List<> of EmojiFlyoutMenu.MenuItem
List<EmojiFlyoutMenu.MenuItem> menuItems = new ArrayList<>();
for (int code : emojiCodes) {
 menuItems.add(new EmojiFlyoutMenu.MenuItem(menuItems.size(), code, fontSizeInMenu, color));

// assign a GridLayout with 2 columns and unspecified rows (allows menu to grow vertically)
smileyFlyoutMenu.setLayout(new FlyoutMenuView.GridLayout(2, FlyoutMenuView.GridLayout.UNSPECIFIED));

// assign the menuItems via an ArrayAdapter
smileyFlyoutMenu.setAdapter(new FlyoutMenuView.ArrayAdapter<>(menuItems));

// create and assign the button renderer. we'll change the button renderer's emoji in the callback below
final EmojiFlyoutMenu.ButtonRenderer renderer = new EmojiFlyoutMenu.ButtonRenderer(emojiCodes[0], fontSizeInButton, color);

smileyFlyoutMenu.setSelectionListener(new FlyoutMenuView.SelectionListener() {
 public void onItemSelected(FlyoutMenuView flyoutMenuView, FlyoutMenuView.MenuItem item) {
  // user has selected an item. update the button renderer's emoji to match
  renderer.setEmojiCode(((EmojiFlyoutMenu.MenuItem) item).getEmojiCode());

 public void onDismissWithoutSelection(FlyoutMenuView flyoutMenuView) {
