I grab some info for you, that might be help for you,

Once setSelectable() is implemented, you can achieve the rest of CHOICE_MODE_MULTIPLE_MODAL by using a regular ActionMode.Callback . Call through to your setSelectable() from within the relevant callback methods:

private ActionMode.Callback mDeleteMode = new ActionMode.Callback() {
        @Override
        public boolean onPrepareActionMode(ActionMode actionMode, Menu menu) {
            setSelectable(true);
            return false;
        }

        @Override
        public void onDestroyActionMode(ActionMode actionMode) {
            setSelectable(false);
        }

        @Override
        public boolean onCreateActionMode(ActionMode actionMode, Menu menu) { ... }

        @Override
        public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem) { ... }
    }

Then use a long click listener to turn on the action mode:

private class CrimeHolder extends SwappingHolder
            implements View.OnClickListener, View.OnLongClickListener {

        ...

        public CrimeHolder(View itemView) {
            ...

            itemView.setOnClickListener(this);
            itemView.setOnLongClickListener(this);
            itemView.setLongClickable(true);
        }

        @Override
        public boolean onLongClick(View v) {
            ActionBarActivity activity = (ActionBarActivity)getActivity();
            activity.startSupportActionMode(mDeleteMode );
            setSelected(this, true);
            return true;
        }
    }
