Question

I am using this method to check how many items on a list a checked and I get this error that this method is not available for any SDK older than 11.

What is the equi

Answer 1

I'm using this code which I believe is efficient and works in all cases:

public int getCheckedItemCount() {
    ListView listView = getListView();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        return listView.getCheckedItemCount();
    }

    SparseBooleanArray checkedItems = listView.getCheckedItemPositions();
    int count = 0;
    for (int i = 0, size = checkedItems.size(); i < size; ++i) {
        if (checkedItems.valueAt(i)) {
            count++;
        }
    }
    return count;
}

Please inform me if you find a case where it doesn't work.
