Have you stepped through the code to ensure that every line is getting
executed as expected and checked the variables list to make sure all
the expected values are set?
The one thing I am curious about is these lines:
todoItems.add(0, myEditText.getText().toString());
myEditText.setText("");
I haven't used in Java in a good 2 years, so I could be forgetting the
specifics, but since Java handles everything as pointers behind the
scenes, when you call setText(""), the pointer that you is created by
todoItems.add() may also be getting set to "" and therefore comes out
blank. Try commenting out the setText(""); and see if that does
anything.
