Android custom Animation for an ArcShape

Question

First let me explain my goal. I am trying to make an Animation that changes the properties of an ArcShape. An ArcShape\'s constructor

Answer 1

I think you might be better off extending Drawable and override the draw() function to modify the sweep angle on each call and draw the corresponding arc. Draw is typically called every time the object is updated, which will mean that you'll have to make a new ArcShape every time it's drawn Animation is more for performing transformations on Views and other UI components.

Something like:

public class OpenPacman  
{

public OpenPacman(float startAngle, float sweepAngle) {  
    this.mStartAngle = startAngle;  
    this.mSweepAngle = sweepAngle;  
    this.wakaWaka = new ArcShape(this.startAngle, this.mSweepAngle);  
} 

public void draw(Canvas c){  
  //Do drawing stuff here with the canvas
}

//Your other functions for calculating angle, etc and making the ArcShape changes
//Can call these from inside draw function so that when the view that contains your
//object calls draw, it updates correctly.

public float mStartAngle;  
public float msweepAngle;  
private ArcShape wakaWaka;  
}

Hope this gets you on the right track.
