4. What is material design?
MATERIAL DESIGN CREATE A VISUAL LANGUAGE FOR USERS THAT SYNTHESIZES THE
CLASSIC PRINCIPLES OF GOOD DESIGN WITH THE INNOVATION AND POSSIBILITY OF
TECHNOLOGY AND SCIENCE. THIS IS MATERIAL DESIGN.
THE ANDROID L DEVELOPER PROVIDES THE FOLLOWING ELEMENTS FOR US TO BUILD
MATERIAL DESIGN APPS:
A NEW THEME
NEW WIDGETS FOR COMPLEX VIEWS
NEW APIS FOR CUSTOM SHADOWS AND ANIMATIONS

5. 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.
5
6. New Widgets
The 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.

7. View Shadows
In 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.

8. 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.
8
9. Continue…
The 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.

10. 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.

o Authentic Motion
o Responsive Interaction
o Meaningful Transitions
o Delightful Details

o 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.

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

13. Animation
o 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

15. 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.
15
16. Animation(Responsive Interaction)
Radial Action
All user initiated actions have an epicenter; the place or places
where their intent enters the system.
Actions should visually connect to their respective input epicenter.
Closer actions occur sooner than more distant ones, creating a
ripple of actions
16
17. Animation
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.
17
18. Examples
Visual 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
18
19. 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.
19
21. Animation
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.
