Q:

Can we have uneditable text in edittext

I am using an EditText. Is it possible to have a part of text uneditable and the rest editable in the same EditText?

A:

You could use
editText.setFocusable(false);
or
editText.setEnabled(false);
although disabling the EditText does currently not ignore input from the on-screen keyboard (I think that's a bug).
Depending on the application it might be better to use an InputFilter that rejects all changes:
editText.setFilters(new InputFilter[] {
    new InputFilter() {
        public CharSequence filter(CharSequence src, int start,
            int end, Spanned dst, int dstart, int dend) {
            return src.length() < 1 ? dst.subSequence(dstart, dend) : "";
        }
    }
});
