You forgot to declare the Button as variable and your variable name is incorrect. It should be "showFactButton" instead of "ShowFactButton". The variable name is case sensitive, so you should be careful when typing.

Here is the answer for the problem: Button showFactButton = (Button) findViewById(R.id.showFactButton);
