One day, I saw an iOS library, which is a view shaker, it's very beautiful. I think Android also need one, and should be better.

So, I started to collect animation effects... and in two days, this project born.

Download Demo

Since Version 2.0, NineOldAndroids has been removed. Thanks Jake Wharton.

For making animations more real, I created another project named Android Easing Functions which is an implementations of easing functions on Android. So, we need to dependent that project.

dependencies {
    implementation 'com.daimajia.androidanimations:library:2.4@aar'
}

<dependency>
    <groupId>com.daimajia.androidanimation</groupId>
    <artifactId>library</artifactId>
    <version>2.4</version>
</dependency>

Just like play Yo-yo.

YoYo.with(Techniques.Tada)
    .duration(700)
    .repeat(5)
    .playOn(findViewById(R.id.edit_area));
