Not sure what you want to do... i assume when you click the button, you want something to happen. In that case, do this:

showFactButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Write your code here //e.g: toast a message } };

Hope it helps.

Happy coding!
