A simple animator library

to-animator

A simple android library for multi elements animator.

Demo

• Simple - with only one animator item.
  
  

• Compose - with multi animator items, and this demo relates to a project of the company, can not be open source for the time being.
  

Usage

This repository can be found on JitPack:

https://jitpack.io/#iwhys/to-animator

1. Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

2. Add the dependency:

dependencies {
    compile 'com.github.iwhys:to-animator:v1.0'
}

3. Implement your animator item extends from the abstract class AnimatorHolder$AnimatorItem:

public class MyAnimatorItem extends AnimatorHolder.AnimatorItem {

    @Override
    protected void onAttached() {
        /**
         * Initialize or reset all properties here, not required.
         * eg:
         * {@link #setDuration(long)}
         * {@link #setInterpolator(TimeInterpolator)}
         * Set the value of {@link #mOriginRect}
         */
    }

    @Override
    protected void onDraw(Canvas canvas, Paint paint) {
        /**
         * Do the real drawing task, required.
         * The canvas is the reference of the target(View/ViewGroup/Drawable),
         * all {@link AnimatorHolder} share with the canvas.
         * The paint is the reference of the {@link AnimatorHolder},
         * all {@link AnimatorHolder.AnimatorItem} share with the paint.
         * This method will be called by the System's VSync signal,
         * and you can get the linear progress by the method {@link #getInputValue()},
         * get the interpolator progress by the method {@link #getProgress()},
         * and then you can set the specify property value with the progress value,
         * and finally easy to implement the animation.
         */
    }
}

4. Custom a View or Drawable to start your animator like this:

public class MyView extends View {

    ......

    private UiAnimator mUiAnimator;

    private void init(){
        mUiAnimator = new UiAnimator(this);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        mUiAnimator.onDraw(canvas);
    }

    @Override
    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        super.onSizeChanged(w, h, oldw, oldh);
        mUiAnimator.targetSizeChanged(w, h);
    }

    @Override
    protected void onDetachedFromWindow() {
        mUiAnimator.destroy();
        super.onDetachedFromWindow();
    }
    
    ......
}
