Button appearance

Use the buttonStyle and touchForward properties to configure the look of the button. The provided styles format the button consistently with overall Alexa visual design.

To set the button style, set the buttonStyle property to one of the following values:

  • contained – Use this style for the main action you want the user to take. This style displays a button filled in with a semi-transparent background color.
  • outlined – Use this style for secondary actions. This style displays a button outlined in a solid color, but with a transparent body.
  • ingress – Use this style for actions such as "confirm", "yes", and "next". This style uses solid colors like contained, but with a different color scheme.
  • egress – Use this style for actions such as "decline", "no", and "previous". This style uses an outline with a transparent body.

Use the touchForward toggle to set the font style for the button according to how you expect users to interact with the button:

  • Set touchForward to false when you expect users to interact with the button with voice. This setting is the default. The button displays the buttonText in an italic font to signify that the user can speak to trigger the button in addition to using touch. Make sure your interaction model lets users select the buttons by voice.
  • Set touchForward to true when you expect users to interact with the button primarily with touch. The button displays the buttonText in a plain font to signify that the buttons are not "speakable".

AlexaButton example

The following example shows a button that uses the default contained and voice-forward settings. When the user selects the button, the button runs the SendEvent command to send a UserEvent to the skill.

{
  "type": "AlexaButton",
  "buttonText": "Button with default settings",
  "id": "idForThisButton",
  "primaryAction": {
    "type": "SendEvent",
    "arguments": [
      "AlexaButton"
    ]
  }
}

This following example shows a complete document and data source that displays the four options in buttonStyle and the two settings for touchForward.
