Android Animation Easing Functions. Let's make animation more real

Android Easing Functions

This project is originally from my another project, AndroidViewAnimation, which is an animation collection, to help you make animation easier.

While, I was still unsatisfied with the animation effect.

So, I started to explore how to make it more and more real.

I found the Easing Functions made by Robert Penne, then, I implemented Easing Functions and make a lovely demo.

minSdkVersion: 11

Step 1

Gradle

compile 'com.android.support:appcompat-v7:25.1.1'
compile 'com.daimajia.easing:library:2.1@aar'

or maven

<dependency>
    <groupId>com.android.support</groupId>
    <artifactId>appcompat-v7</artifactId>
    <version>25.1.1</version>
    <type>apklib</type>
</dependency>
<dependency>
    <groupId>com.daimajia.easing</groupId>
    <artifactId>library</artifactId>
    <version>2.1</version>
    <type>apklib</type>
</dependency>

Step 2

Just like a glider.

AnimatorSet set = new AnimatorSet();
 set.playTogether(
         Glider.glide(Skill.BounceEaseInOut, 1200, ObjectAnimator.ofFloat(mTarget, "translationY", 0, 100))
 );

set.setDuration(1200);
set.start();
