Sorry for the confusion. Here's some relevant code.
My onClickRadioButton():
public void onClickRadioButton(View v) {
View vMain = ((View)v.getParent());
if (radioBut != null) {
radioBut.setChecked(false);
}
radioBut = (RadioButton)v;
if (radioBut.isChecked()) {
listIndex = ((ViewGroup) vMain.getParent()).indexOfChild(vMain);
} else {
radioBut = null;
listIndex = -1;
}
}
It seems that View/ViewGroups relate only to what's visible on the screen?
So, when I use indexOfChild, the index starts from the first visible item
on the screen, rather than the first item of the actual View/Layout. How do
I get the actual index of the list items starting from the very first one,
rather than the first visible one?
Thanks!
