[android-developers] Re: How to use CheckBox as children in ExpandableList?
You are using
final ListView listView = getExpandableListView();
listView.setItemsCanFocus(false);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
but you are extending ExpandableListActivity, not ListActivity. To use
chekboxes properly you have to use mAdapter variable..

Hello kostmo,
use the following code to toggle checkbox
@Override
public boolean onChildClick(ExpandableListView parent, View v, int
groupPosition, int childPosition, long id)
{
CheckedTextView tempView = (CheckedTextView)v.findViewById
(android.R.id.text1);
tempView.setChecked(!tempView.isChecked());
return super.onChildClick(parent, v, groupPosition,
childPosition, id);
}

[android-developers] Re: How to use CheckBox as children in ExpandableList?
Has anyone tried this yet. I am getting strange results. When I click
on one of the check boxes a second one will sometimes become checked
also.
