Android procedural Animation:: XML, Concepts and optimizationProcedural Animation Concepts:tweens and Interpolators

interpolator: http://developer.android.com/reference/android/animation/TimeInterpolator.html

Procedural Animation Data values:ranges and Pivot Point

Range and Center point

procedural Animation Transforms:rotate, scale, Translate scale:One Of them involves size rotation:< Span style= "FONT-SIZE:14PX;" >involves orientation (which direction that something is facing) translation:involves movement procedural Animation compositing:alpha blending  procedural Animation timing:using Duration and Offsets < /span>procedural Animation Loops:repeatcount and repeatmode 

RepeatCount Interger (Loop forever Use Infinite (-1))

Repeatmode:restart (1)

Reverse (2)

The <set> tag:using XML to Group procedural Animation

Android.view.animation

rule of thumb is to apply your transformational parameters locally

Procedural Animation vs. frame animation:the trade-off frame Animation

Memory intensive (requires many other memories): Displaying the image from memory onto the View is fairly straightforward and does not require a NY complex calculations, so all processing involves moving each frame's image asset from memory through to display screen.

Procedural animation

tends to is more processing intensive (many other calculations required)

Creating a procedural Animation Definition Using XML

Animation Pagani = Animationutils.loadanimation (this, r.anim.pag_anim); (view) pag.startanimation (Pagani);

Using Set to Create a more Complex procedural AnimationRotation transformation:going a Bit Too far with FXTweaking Transform values:the Ease of adjusting XML
