Hi Sandra

I suspect you have not implemented the TextView and Button classes into your class. Pressing Alt + Enter together when highlighting the red underlined code should import the class for you, alternatively copy and paste the lines of code below into your java class.

import android.widget.Button;
import android.widget.TextView;

These should go right at the top of the page

Hope the helps

Daniel

I think you should write it in capital case: FactTextView and ShowFactButton

TextView factLabel = (TextView) findViewById(R.id.FactTextView); Button showFactButton = (Button) findViewById(R.id.ShowFactButton);
