Get Cursor Position in Android in Edit Text?

I am using a custom EditText View. I have overridden the OnKeyUp event and am able to capture the Enter Key press. Now my requirement is, when the user has entered a text "Hi. How are you?" and then keeps the cursor after the word "are" and press enter, I need to get the cursor location so that i can extract the text after the cursor at the moment the Enter Key was pressed. Please let me know how to do this. Thank you for your time and help.
