Topic of Study: Working with Animations
Grade/Level: Master of Computer Applications
Objective: To understand the mechanism of different kinds of Animation
Time Allotment: 55 Minutes
- Working with Animations
- The Android platform supports three types of graphics animation:
- Animated GIF images
- Animated GIFs store the animation frames within the image, and you simply include these GIFs like any other graphic drawable resource.
- Frame-by-frame animation
- For frame-by-frame animation, the developer must provide all graphics frames of the animation.
- Tweened animation
- Tweened animation, only a single graphic is needed, upon which transforms can be programmatically applied.
- Working with Frame-by-Frame Animation:
- Step 01: Design the XML.
- Step 02: Write a Java Code.
- Working with Tweened Animation:
- You can provide a single Drawable resource—it is a Bitmap graphic, a ShapeDrawable, a TextView, or any other type of View object.
- Android provides tweening support for several common image transformations, including alpha, rotate, scale, and translate animations.
- You can define tweening transformations as XML resource files or programmatically.
- Defining Tweened Animations as XML Resources:
- Create “anim” folder under /res directory.
- Right click on Anim folder and select other->xml file.
- Copy and Paste xmlns from any xml file.
- Tween Animation – Java Code:
- Scale Operations:
- Exa.
- Alpha Operations:
- Exa.
- Rotate Operations:
- Exa.
- Move Operations:
- Exa.
