Android EditText: How to disable cursor move on touch?

Question

I have EditText which displays something like ###-###. I want the user to be able to change this text only from the 1st position onward. That is user should not be able to touch

Answer 1

Following code will force the curser to stay in last position if the user tries to move it with a tap on the edittext:

edittext.setCursorVisible(false);

    edittext.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            edittext.setSelection(edittext.getText().length());
        }
    });

Note that the user can still change the position of the curser via arrow keys and / or trackball. As far as I know there is currently no workaround for this issue.
