  1. Android App Theming and Styles

  2. What are Styles? Styles define the appearance of UI elements (Views). Collections of attributes (e.g., color, font, size, padding). Applied to individual Views in the layout XML. Promote code reusability. Enable easy UI updates. Reduce code redundancy. Centralize design choices. Styles are the building blocks for customizing individual UI elements.

  3. What are Themes? Themes define the overall look and feel of an activity or an entire app. Collections of named resources (styles, colors, drawables). Provide a central location for design values. Applied at the activity or application level in the manifest. Enable consistency across different screens. Support light/dark mode switching. Allow for dynamic theming. Themes manage broad-based stylistic choices.

  4. Built-in Android Themes

  5. Style Inheritance

  6. Theme Attributes Theme attributes provide semantic names to resources. Examples: ?android:colorPrimary, ?android:colorBackground, ?attr/colorOnSurface Used in styles to reference theme-level values. Allow for dynamic theming changes. Improve code readability. Decouple styles from concrete values.

  7. Using Color Resources Define color resources in colors.xml. Give colors meaningful names (e.g., colorPrimary, colorAccent). Reference color resources using @color/your_color_name. Organize colors for easy updates and theme switching. Maintain color consistency across the app.

  8. Night Mode with DayNight Themes Use Theme.AppCompat.DayNight (or similar) as your app's base theme. Provide alternative resources in the res/values-night directory. Colors, drawables, and styles can be tailored for night mode. The system automatically switches based on user settings. Improves user experience in low-light environments.

  9. Material Components for Theming Provides pre-styled UI elements adhering to Material Design. Includes buttons, text fields, cards, navigation components, and more. Built-in theme attributes for easy customization. Ensures a consistent and modern Android look and feel. Simplifies app development.
