Introduction to material design in Android


     Material design is a comprehensive guide for visual, motion, and interaction design across platforms and devices. 
To use material design in your Android apps, follow the guidelines defined in the material design specification and use the new components and functionality available in Android 5.0 (API level 21) and above.

Android provides the following elements for you to build material design apps:
A new theme
New widgets for complex views
New APIs for custom shadows and animations
Following are the major introduction with Material Design APIs.

Material Theme
The material theme provides a new style for your app, system widgets that let you set their color palette, and default animations for touch feedback and activity transitions.
Lists and Cards
Android provides two new widgets for displaying cards and lists with material design styles and animations:

View Shadows
In addition to the X and Y properties, views in Android now have a Z property. This new property represents the elevation of a view, which determines:

  • The size of the shadow: views with higher Z values cast bigger shadows.
  • The drawing order: views with higher Z values appear on top of other views.

Animations
The new animation APIs let you create custom animations for touch feedback in UI controls, changes in view state, and activity transitions.

These APIs let you:

  • Respond to touch events in your views with touch feedback animations.
  • Hide and show views with circular reveal animations.
  • Switch between activities with custom activity transition animations.
  • Create more natural animations with curved motion.
  • Animate changes in one or more view properties with view state change animations.
  • Show animations in state list drawables between view state changes.
  • Touch feedback animations are built into several standard views, such as buttons. The new APIs let you customize these animations and add them to your custom views.

We will see these things one by one in coming posts.
