Buttons let the user trigger a defined action. There are five types of button:
Type |
Appearance |
Purpose |
---|---|---|
Filled | Solid background with contrasting text. |
For primary actions, such as "Submit" and "Save." The shadow effect emphasizes the button's importance. |
Tonal | Background color varies to match the surface. |
For primary or significant actions. Filled buttons provide visual weight and are appropriate for actions like "Add to cart" and "Sign in." |
Elevated | Shadow makes it stand out. |
For primary or significant actions. Increase elevation to make the button more prominent. |
Outlined | Features a border with no fill. |
For actions that are important but not primary. Outlined buttons pair well with other buttons to indicate alternative, secondary actions like "Cancel" or "Back." |
Text | Text with no background or border. |
For less critical actions such as navigational links, or secondary actions like "Learn more" or "View details." |
Version compatibility
This implementation requires that your project minSDK be set to API level 21 or higher.
