Android Material Design has revolutionized the way we interact with apps, and one of the most crucial elements of this design language is the humble button. Buttons are the gateways to actions, interactions, and ultimately, user satisfaction. Understanding the nuances of Android Material Design button styles empowers developers to create intuitive and visually appealing interfaces that enhance user experience. This comprehensive guide dives into the various button styles, exploring their functionalities and showcasing how to implement them effectively in your Android projects.

Contained Buttons

Contained buttons are the workhorses of Material Design. They are visually prominent, clearly indicating interactive elements. Their solid background color and elevation make them stand out against the app’s background. Contained buttons are best suited for primary actions within a screen, guiding users towards key functionalities. They are especially effective when placed on backgrounds with ample contrast.

For example, in a shopping app, the “Add to Cart” button would be a prime candidate for a contained button style. Its visual prominence draws the user’s attention, encouraging interaction and driving conversions. Another common use case is the “Submit” button on a form, signifying the completion of a process.

Implementing contained buttons is straightforward using the Material Design Components library. Simply use the <Button> element with the app:backgroundTint attribute to define the button’s background color.

Outlined Buttons

Outlined buttons provide a lighter touch compared to their contained counterparts. They feature a transparent background with a colored border, creating a subtler visual presence. This makes outlined buttons suitable for secondary actions or actions that are less critical within the overall user flow. They contribute to a cleaner, less cluttered interface.

Consider a scenario where you have a “Filter” button alongside a primary “Search” button. Using an outlined style for the “Filter” button allows it to perform its function without overshadowing the main call to action. This hierarchy of visual prominence contributes to a more intuitive user experience.

To create outlined buttons, you can use the <Button> element with the app:strokeColor attribute to define the border color and set app:backgroundTint to @null for a transparent background.

Text Buttons

Text buttons represent the most minimalist approach to button design in Material Design. Comprising only text, they blend seamlessly into the surrounding content. Text buttons are ideal for actions that don’t require strong visual emphasis, such as “Cancel” or “Learn More.” They maintain a clean aesthetic while still providing clear interactivity.

Imagine a dialog box with the options “Discard” and “Save.” A text button style for “Discard” minimizes its visual weight, subtly suggesting it’s a less preferred action compared to the more prominent “Save” button. This nuanced visual hierarchy helps guide user decisions.

To implement text buttons, you again use the <Button> element but remove any background or border styling, relying solely on the text color for visual distinction.

Toggle Buttons

Toggle buttons allow users to select from two or more states. They are commonly used for options like “On/Off” or “Yes/No.” Visual cues clearly indicate the selected state, providing immediate feedback to the user. This makes toggle buttons perfect for settings or preferences within an app.

A classic example is the Wi-Fi toggle in Android’s quick settings panel. The button’s appearance changes to reflect whether Wi-Fi is enabled or disabled, providing instant visual confirmation of the user’s selection.

Implementing toggle buttons involves using the <ToggleButton> or <Switch> components, customizing their appearance for different states using selectors and state lists.

“Effective button design is essential for creating a user-friendly and engaging mobile experience. Material Design provides a robust framework for building buttons that are not only visually appealing but also functionally intuitive.” - John Doe, Senior UX Designer at Example Company

• Choose the right button style based on its intended function and visual hierarchy.
• Ensure sufficient contrast between the button and its background for accessibility.

1. Select the appropriate button type (Contained, Outlined, Text, or Toggle).
2. Customize the appearance using attributes like app:backgroundTint and app:strokeColor.
3. Implement the button’s functionality in your application logic.

FAQ

Q: How do I choose the right button style?

A: Consider the button’s primary function and its visual importance within the overall interface. Contained buttons are for primary actions, outlined buttons are for secondary actions, text buttons are for subtle actions, and toggle buttons are for switching between states.

Q: Can I customize the appearance of Material Design buttons?

A: Yes, you can customize attributes like background color, border color, text color, and elevation to align with your app’s branding and overall visual style.

Question & Answer :
I’m confused on button styles for material design. I’d like to get colorful raised buttons like in the attached link., like the “force stop” and “uninstall” buttons seen under the usage section. Are there available styles or do I need to define them?

http://www.google.com/design/spec/components/buttons.html#buttons-usage

I couldn’t find the default button styles.

Example:

<Button style="@style/PrimaryButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Calculate" android:id="@+id/button3" android:layout_below="@+id/editText5" android:layout_alignEnd="@+id/editText5" android:enabled="true" /> 

If I try to change the background color of the button by adding

android:background="@color/primary" 

all of the styles go away, such as the touch animation, shadow, rounded corner, etc.

I will add my answer since I don’t use any of the other answers provided.

With the Support Library v7, all the styles are actually already defined and ready to use, for the standard buttons, all of these styles are available:

style="@style/Widget.AppCompat.Button" style="@style/Widget.AppCompat.Button.Colored" style="@style/Widget.AppCompat.Button.Borderless" style="@style/Widget.AppCompat.Button.Borderless.Colored" 

Widget.AppCompat.Button:

Widget.AppCompat.Button.Colored:

Widget.AppCompat.Button.Borderless

Widget.AppCompat.Button.Borderless.Colored:

To answer the question, the style to use is therefore

<Button style="@style/Widget.AppCompat.Button.Colored" ....... ....... ....... android:text="Button"/> 

How to change the color

For the whole app:

The color of all the UI controls (not only buttons, but also floating action buttons, checkboxes etc.) is managed by the attribute colorAccent as explained here. You can modify this style and apply your own color in your theme definition:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> ... <item name="colorAccent">@color/Orange</item> </style> 

For a specific button:

If you need to change the style of a specific button, you can define a new style, inheriting one of the parent styles described above. In the example below I just changed the background and font colors:

<style name="AppTheme.Button" parent="Widget.AppCompat.Button.Colored"> <item name="colorButtonNormal">@color/Red</item> <item name="android:textColor">@color/White</item> </style> 

Then you just need to apply this new style on the button with:

android:theme="@style/AppTheme.Button" 

To set a default button design in a layout, add this line to the styles.xml theme:

<item name="buttonStyle">@style/btn</item> 

where @style/btn is your button theme. This sets the button style for all the buttons in a layout with a specific theme
