Hi! Your material design switch is cool!

But, how to read the state of the switch? I know that I receive the boolean flag in my onchangestatelistener but not the id of the view that did launched the event. Because of that I try to determine the state of each view, but I don't find the method to read the state.

Como creo que eres español, te lo comento en español ya que mi ingles no es muy bueno. El componente me parece genial, esta diseñado con mucho gusto, pero no encuentro como leer el estado del switch. ¿Hay algun metodo tipo isChecked o algo asi?

Un saludo y gracias.

i change the width and height in my xml file ,but size never change . Looking into the source code, you hardcode the size for 45dp 28dp ,not supporting wrap_content or other fixed size?

this is now full of bugs and once you update gradle pass 3.5.3 you get this message Failed to resolve: com.github.glomadrian:MaterialAnimatedSwitch:1.1 Show in Project Structure dialog Affected Modules: app !!!!regardless of whatever solution you can find online regardless where you position maven

IT IS NOT WORKING ANYMORE

In this release I've made some fix on some bugs on BallPainter class. I also make the code compatible with androidx and the last version of Android Studio (3.6) The compile version has also been update to api 29.

I have an app like uber. Lets assume that the rider has already requested a ride. Once the driver goes online, then the request is seen but if the rider doesn't request a ride until after the driver goes online, the request is not seen. Is there anything else I can do other than if online or if offline? I tried doing switch.isChecked() but nothing changed.

Added function to enable and disable switch. To enable materialAnimatedSwitch.setClickable(true); To diable materialAnimatedSwitch.setClickable(false); Before that add setClickableManageByLibrary(false);
