Android Animation Easing Functions

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

implementation 'com.android.support:appcompat-v7:25.1.1'
implementation '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();

Tips

If you encounter exceptions such as ClassNotFoundExceptions (#4), please add the following to your proguard-project.txt:

-keep class com.daimajia.easing.** { *; }
-keep interface com.daimajia.easing.** { *; }
