            }
        };

this is my code help me out?

Kalpana, I checked your code. Yes, It is not showing cursor. I suggest you to use EditField instead of BasicEditField. You can override these methods for Editfield also. I tried it and it is showing cursor.

I think I may have solved this by adding another field to the manager before this custom BasicEditField. Add a field that doesn't do anything. Something like this:

BitmapField bugFix = new BitmapField(Bitmap.getBitmapResource("empty_image.png"));
myFieldManager.add(bugFix);
myFieldManager.add(demo);

However, what I found is that the size of the dummy field (BitmapField in this case) matters. If your "empty_image.png" image is only 2px high, only the top 2px of the cursor will display. So, if you can deal with the extra padding, add a field that has at least 20px or so and the entire cursor should display. I should also add that this bug does not seem to show up on any subsequent custom BasicEditFields that you add to the manager... only the first one. Hmmm...
