Android additive animations

Additive animations for Android! An easy way to additively animate a huge number of properties.

Quick start

Here is a sample of what additive animations can do to the user experience (note: there seem to be a few dropped frames in the gif which aren't present when running on a device):

The amount code required to produce this animation is trivial:

public boolean onTouch(View v, MotionEvent event) {
    AdditiveAnimator.animate(animatedView).x(event.getX()).y(event.getY()).setDuration(1000).start();
    return true;
}

Additionally, AdditiveAnimator supports animating multiple views simultaneously without any boilerplate:

new AdditiveAnimator().setDuration(1000)
                      .target(myView1).x(100).y(100)
                      .target(myView2).xBy(20).yBy(20)
                      .start();

Integration

To use AdditiveAnimator in your project, add the following lines to your build.gradle:

dependencies {
    compile 'at.wirecube:additive_animations:1.3.1'
}
...
repositories {
    jcenter()
}
