1) the person you tagged doesn't seem to be an active member on treehouse
2) I inputted your code into a blank project, and I see what could be potentially your problem. In your design, you see you have a TextView right? But in your main code you wrote this:
mEditText = (EditText) findViewById(R.id.editText);
I think you might have accidentally used a textview instead of an edittext :)
Tell me if that fixes your problem!!
Happy Thanksgiving
