    Android Frame Animation: XML, Concepts and Optimization

    Frame Animation Concepts: Cels, Framerate, and Resolution

    动画的发展

      cel-base animation

    raster animation

    bitmap

    commonly called bitmap animation

    not currently support Animated GIF

    Optimizing Frame Animation: Color Depth and Frame Rate

    three primary ways to optimize

    reduce the resolution 

    reduce the color depth

    and reduce the framerate

    格式:PNG32,Png8

    If you don’t need to composite your animation over other graphics, you can also consider using the lossy JPEG format to get a far smaller per-frame data foot print by throwing away some of the image data and resulting quality.

    应该考虑硬件条件, 处理器及内存


    Creating Frame Animation in Android Using XML Markup

    Frame animation uses the drawable resource folder 

    animation (covered in Chapter 4) uses the /res/anim folder

    AnimationDrawable

    Android <animation-list> Tag: The Parent Frame Container

    Android's <item> Tag: Specifying Your Animation Frames

    Creating a Frame Animation for our GraphicsDesign App

    Instantiating the Frame Animation Definition Using Java

    AnimationDrawable drawable = (AnimationDrawable) imageView.getDrawable();

    drawable.start();
