Observing check state

View reacts to clicks and maintains the state on its own. To listen to the check state change, implement the following callback.

import co.ankurg.expressview.OnCheckListener
likeButton.setOnCheckListener(object : OnCheckListener {
    override fun onChecked(view: ExpressView?) {
        Log.d(TAG, "Checked")
    override fun onUnChecked(view: ExpressView?) {
        Log.d(TAG, "Unchecked")
