Android Build a Simple Android App (2014) Basic Android Programming Making a Button Do Something


I get a "Cannot resolve symbol 'setOnClickListener'" when I enter showFactButton.setOnClickListener();

I had to import the Button library to resolve another error, but am I missing a library. I don't see "set..." show up at all in the auto complete for the method.

Double-check your code and compare it to the video, just to be safe. Also, can you paste your code here for us to see?

Try something like this.

final View.OnClickListener listener = new View.OnClickListener()

If you're using Android Studio, it'll prompt you to impliment the unused method and that will add the method needed to define what the listener will do. After the method, outside of its scope, declare your .setOnClickListener(listener);

If I had a peek at your code, I'd be able to help you with your specific problem. :) Be sure to update the question with a snippit of your code!
