Android Build an Interactive Story App (Retired) Intents and Multiple Activities Adding a Second Activity

Code Switched In The Video (Unknown Reason)

Hello, I am confused to why the code has changed and how I should be looking at it? In the last activity, line 24 code was set up as follows.

***Java mStartButton.setOnClickListener(new View.OnClickListener());

Today, I am trying to add a second activity and my code now doesnt match up to what we were shown to use in the last video. It just jumps from the last code to the new code with no explanation. Here is what line 24 now looks like:

***Java mStartButton.setOnClickListener((v) -> { };

I was wondering if I missed something or if I am just blind. Any help would be great! Thanks, Andrew :)

Hey Andrew!

This is part of Android Studio and it does this to make your code easier to read. If you click on the code, it will expand it out back to how it was earlier.

Hope it helps :)
