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
