How to change the style of a button in Android Studio: a complete guide

The visual appeal of an application plays a decisive role in user retention, and standard interface elements often require improvement. A standard widget Button in Android looks utilitarian and may not correspond to the brand book of your project. Changing the style of a button in Android Studio is a fundamental skill that allows you to create a unique user experience (UX) and differentiate your product from competitors.

Modern Android development offers a variety of styling tools, from simple XML attributes to complex themes based Material Design Components. You can change the color, shape, shadows, click animation, and even completely redraw the element using vector graphics. Understanding these mechanisms is necessary for every developer who strives to create high-quality interfaces.

In this article we will analyze all the current ways to customize buttons, starting from basic settings in the layout and ending with creating your own styles. We'll look at the difference between legacy methods and modern approaches to ensure your code remains relevant and maintainable in the long term.

Basic customization via XML attributes

The fastest way to change the appearance of a button is to use built-in attributes directly in the markup file. To do this, just open the file activity_main.xml and add parameters to the tag Button. You can change the background color using the android:backgroundTint attribute and the text color via android:textColor. This solution is ideal for prototyping or simple tasks where complex logic is not required.

However, it is important to understand that directly setting colors in the layout complicates dark theme support. If you hardcode the background color to white, the button may become unreadable in dark mode. Therefore, for background and text colors, it is better to use links to resources from the folder colors.xml or theme attributes, such as ?attr/colorPrimary. This will ensure automatic adaptation of the interface to the system settings of the device.

It is also worth paying attention to the android:layout_width i android:layout_heightattribute. By default, buttons often have a height set by the system, but you can fix the sizes or use wrap_content for adaptability. Don't forget about indents: the attribute android:padding allows you to add “air” around the text inside the button, making it visually lighter and more pleasant to press.

⚠️ Attention: Using the attribute android:background to set the color completely replaces the standard widget background, including click effects (ripple effect). If you need to save the click animation, use backgroundTint instead of directly setting the background.

Creating your own styles in styles.xml

To maintain code cleanliness and reuse of designs, it is recommended to move settings to a file res/values/styles.xml (or themes.xml in new projects). A style is a collection of properties that are applied to a widget as a whole. This allows you to change the appearance of all the buttons in the application, editing the code in only one place, which is critical for large-scale projects.

To create a new style, add a tag <style> with a unique name, for example CustomButtonStyle. Inside it, define the necessary attributes, such as android:textSize, android:textAllCaps (to disable Android-specific automatic uppercase) and android:fontFamily. The use of fonts is especially important for branding, since typography sets the tone for the entire interface.

Applying style to a button is done through the attribute style="@style/CustomButtonStyle". Please note that styles can be inherited. You can create a base style for all of your app's buttons, and then create child styles for specific use cases, such as cancel or confirm buttons. This hierarchy simplifies design management.

When working With styles, it is important to distinguish between Android platform attributes (prefix android:) and support library attributes (without prefix). For example, the property cornerRadius (corner rounding) is available only in Material Design components and does not have a prefix android. An error in writing the prefix will result in the attribute being simply ignored by the compiler, and the visual effect will not be applied.

Using Material Design Components

The modern standard for interface design in Android is Material Design. Instead of a regular widget Button Google recommends using com.google.android.material.button.MaterialButton. This component provides advanced features out of the box, including icon support, various form options, and built-in states.

To connect, you must make sure that the dependency build.gradle . After replacing the class in the XML file, you will have access to attributes such as implementation 'com.google.android.material:material:...' is added to the file app:cornerRadius to control the rounding of corners and app:strokeColor c app:strokeWidth to create outline buttons. Outline buttons are often used for minor actions, so as not to overload the interface.

MaterialButton also simplifies working with icons. You can add an icon to the left or right of the text using the app:icon and app:iconGravityattributes. The size of the icon is adjusted via app:iconSize, and the color - via app:iconTint. This eliminates the need to create complex layouts with LinearLayout or ConstraintLayout simply to place an image next to the text.

Attribute	Description	Example value
app:cornerRadius	Radius button corner rounding	16dp or 0dp
app:backgroundTint	Background color (supports selectors)	@color/primary
app:strokeColor	Stroke color for outline buttons	@color/black
app:elevation	Shadow height (for Material 2)	4dp

Working with shapes and rounded corners

Rectangular buttons with sharp corners are a thing of the past, giving way to softer shapes. Rounding corners (borderRadius) is one of the most common requests in interface design. In standard Button this is implemented in a complex manner by creating a separate form file (shape), but in MaterialButton this is done with one attribute.

If you still use a standard widget or ImageButton, you will need to create a file resource type drawable. Inside it, a tag <shape> with a parameter <corners android:radius="..." />is described. This file is then included as the background. This approach gives complete freedom: you can round only the top corners or make the button oval by setting a radius equal to half the height of the element.

Modern versions of Android also allow you to use the attribute android:clipToOutline in conjunction with a background-form. This ensures that the elevation and ripple effect follow the shape of your rounded background, rather than extending beyond the rectangular area. Without this property, the button may look square with a shadow, even if the background inside is round.

⚠️ Attention: The fillet radius value must be a multiple of the screen density or set in dp. Setting the radius too large on small buttons can lead to visual artifacts or turn the button into a perfect circle, which is not always the desired effect.

How to make a button completely round?

Set the button's height and width equal (for example, 50dp by 50dp) and set the cornerRadius to 25dp (half a side). For MaterialButton, this will work automatically.

Animation and click effects (Ripple Effect)

Feedback during interaction is a key element of good UX. When a user clicks a button, they should see a visual response. In Android this effect is called Ripple (ripple). By default, it is present in all standard buttons, but when customizing the background, you can accidentally lose it.

To save or customize the ripple effect, use the attribute android:foreground (for containers) or a special background property. In MaterialButton the click effect is built-in and automatically adapts to the color of the button. You can change the color of the “wave” itself using the android:colorControlHighlight attribute in the theme or creating a custom one. ripple drawable.

To create complex animations, such as smooth resizing or moving a button when pressed, you can use StateListAnimator. This XML resource allows you to describe property changes (for example, translationZ or scaleX) depending on the state of the button: pressed, focused, or enabled. This adds “liveness” and tactility to the interface.

Common errors and ways to solve them

When styling buttons, developers often encounter a problem when the specified color is ignored. Most often this happens due to topic priority. If set colorButtonNormalin the application theme, it may override local settings in XML. The solution is to explicitly specify the attribute android:backgroundTint or use a style with high priority.

Another common mistake is incompatible library versions. If you use MaterialButtonbut the version of the library Material Components b build.gradle is outdated, some attributes (for example iconTint) may simply not work or cause the application to crash on older devices. Always check version compatibility when updating dependencies.

It's also worth keeping Accessibility in mind. When changing text or background color, ensure that the contrast remains sufficient for people with visual impairments to read. Android Studio tools can tell you if the text color you choose against the selected background has too low a contrast ratio.

⚠️ Note: The interfaces and attribute names in Android Studio may change as new versions of the Jetpack SDK and libraries are released. If an attribute is not suggested by the code editor, check the official documentation for the specific version of the Material Components library that you are using in the project.

FAQ: Questions and Answers

How to change the color of just one specific button without creating a style?

You can use the attribute android:backgroundTint="@color/your_color" directly in the button tag in the XML file. This will override the color for this instance only, without affecting the rest of the interface.

Why is the text on a button always shown in capital letters?

This is standard Android behavior for buttons. To disable it, add an attribute android:textAllCaps="false" to the XML or a property textAllCaps="false" to your style.

Can the button be made transparent?

Yes, set android:background="@android:color/transparent" or use app:backgroundTint="@android:color/transparent" for MaterialButton. Do not forget to set the color of the text, otherwise it will not be visible.

How to add an icon inside a button without using ImageView?

When using MaterialButton just add an attribute app:icon="@drawable/your_icon". You can also control the position of the icon via app:iconGravity (start, textStart, top, end).

What is the difference between Button and MaterialButton?

Button is a standard platform widget with basic functionality. MaterialButton is an advanced component from Google, supporting modern design standards, icons, strokes and improved work with themes.
