Possible to put CheckedTextView into Group like RadioGroup?

Question

Is there a way to have multiple CheckedTextView in some sort of group like RadioGroup? So only one CheckedTextView would be checked at the same time.

If this is not possible as CheckedTextView is a child of TextView, what is the most memory efficient way to code logic that only one CheckedTextView can be checked in the group of 5 other CheckedTextViews?

It does not look memory efficient that each time one CheckedTextView is pressed, I check for the check state of all others and change it accordingly.

The simplest way is to use custom drawable like checkbox for radio buttons.. — Pankaj Kumar, Jun 03 '14 at 05:20
Thanks. This link also helped me to create my own logic http://stackoverflow.com/a/14509329/437039 — sandalone, Jun 03 '14 at 06:29

I managed to do it with CheckedTextView to behave as part of some group (e.g. only one CheckedTextView can be selected at a time).

//pass view which fired onClick event
//pass an array or other container of checkedTextViews (optional)
void setCheckedState(View v, CheckedTextView[] whichCheckedViews) {
    CheckedTextView temp = (CheckedTextView) v;

//first uncheck all views in the arraw
    for (CheckedTextView item : whichCheckedViews)
        item.setChecked(false);

//detect which checkedTextView initiated onClick event
    switch (v.getId()) {
        case R.id.checkedTextView_1:
        case R.id.checkedTextView_2:
        case R.id.checkedTextView_3:
        case R.id.checkedTextView_N:
            temp.setChecked(true);
            break;

        default:
            break;
    }
}

And this works like a charm.

NOTE: I did not check memory consumption since I have only 5 views. I also did not check execution time since on all test devices it runs without a glitch.
