I2C adapter and oneWire sensor

I'm feeling some confusion with my project. I have a DS18B20 temp sensor connected and it works great. I have a Sunfounder LCD connected to an inexpensive I2C adapter and it works just fine with this test library found here: Bitbucket

I'd like to print the data from the oneWire sketch to the LCD but am not sure how to go about doing so. Maybe I'm a bit confused on the serial.println vs lcd.print.
Is there any suggestion how to do this?
