I'm trying to implement multiple list item selection and user can perform actions based on menu item appears on actionbar.
I have tried a way ListView.CHOICE_MODE_MULTIPLE_MODAL
but this option works only for API 11 or above.
Is there a way we can make use of the same technique for API 11 below i.e below code works only API 11 onwards.
list.setMultiChoiceModeListener(new MultiChoiceModeListener() {
@Override
public void onItemCheckedStateChanged(ActionMode mode,
int position, long id, boolean checked) {
// Capture total checked items
final int checkedCount = list.getCheckedItemCount();
// Set the CAB title according to total checked items
mode.setTitle(checkedCount + " Selected");
// Calls toggleSelection method from ListViewAdapter Class
listviewadapter.toggleSelection(position);
}

Using ActionBarSherlock the MultiChoiceModeListener if you want to support API level < 11.
A workaround is to use the onItemClickListener.
List setup:
listView = (ListView) timeline.findViewById(android.R.id.list);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setItemsCanFocus(false);
listView.setAdapter(new ListAdapter(getActivity(), R.layout.cleaning_list_item, items));
Listener of ListFragment or ListActivity:
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
SparseBooleanArray checked = listView.getCheckedItemPositions();
boolean hasCheckedElement = false;
for (int i = 0; i < checked.size() && !hasCheckedElement; i++) {
hasCheckedElement = checked.valueAt(i);
}
if (hasCheckedElement) {
if (mMode == null) {
mMode = ((SherlockFragmentActivity) getActivity()).startActionMode(new MyActionMode());
mMode.invalidate();
} else {
mMode.invalidate();
}
} else {
if (mMode != null) {
mMode.finish();
}
}
}
Where MyActionMode is an implementation of ActionMode.Callback:
private final class MyActionMode implements ActionMode.Callback { /* ... */ }
