June 25, 2014Android L Preview

Material Theme

The material theme provides a new style for our app, system widgets that let us set their color

palette, and default animations for touch feedback and activity transitions.

Material Design

● Universal platform design that functions across Android Wear, Android TV, Android Auto, and all of Google’s apps and services

● Making the whole device feel unified ● Its all about everything animation, but flat at the same

time ● Elevation value to any UI surface to get 3D effects by

virtual light sources and real time shadows

Material Theme

● Material Design ● Android RunTime (ART) ● Battery life (Project Volta) ● Security ● Multitasking and Recent App ● Notifications ● Many more...

New WidgetsThe Android L Developer Preview includes two new widgets for displaying complex views: ● The new RecyclerView widget is a More

advanced version of ListView. ● The new CardView widget lets us Important

pieces of information inside Cards that have a consistent look and Feel.

View ShadowsIn addition to the X and Y properties, views in the Android L Developer 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 Android L Developer provides new APIs

that let us to create custom animations for touch feedback in UI controls, view state changes, and activity transitions.

● Touch feedback animations are built into several standard views such as buttons.

● The new APIs let us customize these animations and add animations to our custom views

AnimationsThe new animation APIs let us: ● Respond to touch events in our views with touch

feedback animations. ● Hide and show views with reveal effect animations. ● Switch between activities with custom activity transition

animations. ● Create more natural animations with curved motion. ● Show animations in state list drawables between view

state changes.

Principles of Material● Design Material is the metaphor : A material

metaphor is the unifying theory of a rationalized space and a system of motion.

● Bold, graphic, intentional : These elements do far more than please the eye; they create hierarchy, meaning, and focus.

● Motion provides meaning : Motion is meaningful and appropriate, serving to focus attention and maintain continuity.

Animation has four contents● Authentic Motion● Responsive Interaction● Meaningful Transitions● Delightful Details

Animation● Authentic Motion

Perceiving an object's tangible form helps us understand how to manipulate it. Observing an object's motion tells us whether it is light or heavy, flexible or rigid, small or large.

● Contents Mass and Weight: Physical objects have mass and move only when forces are applied to them.Objects can’t start or stop instantaneously.

Animation● Responsive Interaction

Responsive interaction builds trust with the user and engages them. It is thoughtful and purposeful, not random, and can be gently whimsical but never distracting.

In material design, apps are responsive to and eager for user input:

● Touch, voice, mouse and keyboard are all first-class input methods ● Although UI elements appear tangible, they are locked behind a layer

of glass

Animation(Responsive Interaction)Surface Reaction One way to express this acknowledgment is through the ink metaphor, the dynamic display surface that coats every sheet of paper.

Animation(Responsive Interaction)● Material Response ● In addition to ink-like actions on the surface, the material itself

can also respond to interaction. ● The material can lift up when touched or clicked, indicating an

active state. ● Material appears from touch point. ● Paper appears from center of screen, breaking relationship with

input.

Animation(Responsive Interaction)Meaningful Transitions ● It can sometimes be difficult for a user to know where to focus

their attention in an app or how an app element got from point A to point B.

● Motion design should not only be beautiful, but serve a functional purpose.

ExamplesVisual Continuity ● Transitioning between two visual states should be smooth,

appear effortless, and above all, provide clarity to the user, not confusion.

A transition has three categories of elements: ● Incoming elements ● Outgoing elements ● Shared elements

Animation(Meaningful Transitions)Hierarchical Timing ● When building a transition, consider both the order in which

elements move and the timing of their movement. ● It Ensure that motion supports the information hierarchy.

Animation(Meaningful Transitions)Consistent Choreography ● As transitioning elements move around the screen. ● They should behave in a coordinated manner.

Animation(Meaningful Transitions)Delightful Details ● Animation can exist within all components of an app and at all

scales, from finely detailed icons to key transitions and actions. ● All elements work together to construct a seamless experience

and a beautiful, functional app.

What were the goals?

…synthesize the classic principles of good design with the innovation and possibility of technology and science…

…single underlying system that allows for a unified experience across all platforms…

…touch, voice, mouse and keyboard are all first-class input methods…

Material Design

Material design is a comprehensive guide for visual, motion, and interaction design across

platforms and devices.

What if we could design for materials of the future instead of

materials that we use today? - Matias Duarte”
