setCustomSelectionActionModeCallback(new ActionMode.Callback() {
public boolean onCreateActionMode(ActionMode actionMode, Menu menu) {
return false;
}
public boolean onPrepareActionMode(ActionMode actionMode, Menu menu) { return false; }
public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem) { return false; }
public void onDestroyActionMode(ActionMode actionMode) {}
});
