What am i doing wrong?

Question - Initialize the getAnswerButton variable using the findViewById() method like the TextView above it. The ID for the button is 'button1', and don't forget to cast it to a Button with '(Button)'!

My Answer - Button getAnswerButton = (Button) findviewById(R.id.button1);

you need to capitalize the v in View

Button getAnswerButton = (Button) findViewById(R.id.button1);

Actually I found that by removing '(Button)' and just leaving 'findViewById(R.id.button1);'fixes the issue. Which leaves me to wonder why they tell us to remember to add the (Button) to it...

This is just a guess but findviewbyid most likely returns a basic view type, so if you want to assign the return value to a button you have to cast that returned view to a button using (Button)
