Note sure what's going on, but this loop:
boolean hasCheckedElement = true;
for (int i = 0; i < checked.size() && !hasCheckedElement; i++) {
hasCheckedElement = checked.valueAt(i);
}
will not execute ever, because "&&!hasCheckedElement" is always false,
since "hasCheckedElement = true".
The loop is redundant anyway, since the SparseBooleanArray is either null
or empty, or has elements, which can be checked without a loop.
I also don't see where you set "mActionMode" to null in the "finish" case.
Finally, multiple-choice element selection is performed by
ListView.setItemChecked(position, true/false), and I don't see your code
calling that. If you did, the action mode would be started and terminated
automatically, IIRC.
Take all this with a grain of salt since I've not used ActionBarSherlock,
but these are the things I would check.
