FlyoutMenus

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.


XML

<org.zakariya.flyoutmenu.FlyoutMenuView  android:id="@+id/myMenu"  android:layout_width="wrap_content"  android:layout_height="wrap_content"  android:layout_marginBottom="@dimen/flyout_menu_button_margin"  android:layout_marginLeft="@dimen/flyout_menu_button_margin"  android:layout_marginRight="@dimen/flyout_menu_button_margin"  android:layout_marginTop="@dimen/flyout_menu_button_margin"  app:fmButtonSize="@dimen/flyout_menu_button_size"  app:fmItemHeight="@dimen/palette_menu_item_size"  app:fmItemMargin="0dp"  app:fmItemWidth="@dimen/palette_menu_item_size"  app:fmMenuAnchor="top"  />

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

Java

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) {

 super(id);

 this.emojiCode = emojiCode;
 this.emojiString = getEmojiByUnicode(emojiCode);

  textPaint = new TextPaint();

 textPaint.setTextSize(size);

 textPaint.setTextAlign(Paint.Align.CENTER);

 textPaint.setStyle(Paint.Style.FILL);

 textPaint.setColor(color);

}

 public int getEmojiCode() {

 return emojiCode;

}

 @Override
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) {

 super();

  this.setEmojiCode(emojiCode);

  paint = new Paint();

 paint.setAntiAlias(true);

  textPaint = new TextPaint();

 textPaint.setTextSize(size);

 textPaint.setTextAlign(Paint.Align.CENTER);

 textPaint.setStyle(Paint.Style.FILL);

 textPaint.setColor(color);

}

 public int getEmojiCode() {

 return emojiCode;

}

 public void setEmojiCode(int emojiCode) {

 this.emojiCode = emojiCode;
 this.emojiString = getEmojiByUnicode(this.emojiCode);

}

 @Override
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(R.id.smileyFlyoutMenu);

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.setButtonRenderer(renderer);
  smileyFlyoutMenu.setSelectionListener(new FlyoutMenuView.SelectionListener() {
  @Override  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());
  
}

@Override  public void onDismissWithoutSelection(FlyoutMenuView flyoutMenuView) {
  
}
 
}
);
