I like this library, but how implement it in Java? sample app in Kotlin, I have tried to understand but can't.

Finally, I can use this library in Java. Thanks to @sephiroth74 and thanks to om [yohanes](https://github.com/yohanes) for helping me to use this library :) Sample in Java available [here](https://github.com/indrabsudirman/Tri-State-Checkbox/blob/b2e1f14d6d1b26e2190448872339526f88d28ee0/app/src/main/java/it/sephiroth/android/library/demo/MainActivity2.java)
