问题
I noticed a method called Post in Android's Button class. I was wondering what this method was for? This method takes a runnable argument, my question is when should we use this vs just having a listener bind to the click event of this button? What is the difference? Any example is appreciated.

post() is inherited from View. It has nothing to do with button clicks and is not a replacement for an OnClickListener. post() is used to arrange for a Runnable to be executed on the main application thread, typically by some code running on a background thread.
