и вы можете попробовать это со своим кодом

`

    public class MyActivity extends Activity  {

private ListView listView;

 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);

     listView .setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
     listView .setMultiChoiceModeListener(callback);

     final ActionMode.Callback callback = new ActionMode.Callback() {
         /** Invoked whenever the action mode is shown. This is invoked immediately after onCreateActionMode */
 @Override
 public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
     return true;
 }


 /** Called when user exits action mode */
 @Override
 public void onDestroyActionMode(ActionMode mode) {

 }

 /** This is called when the action mode is created. This is called by startActionMode() */
 @Override
 public boolean onCreateActionMode(ActionMode mode, Menu menu) {
     mode.setTitle("Demo");
     getMenuInflater().inflate(R.menu.edit_vow, menu);
     return true;
 }

 /** This is called when an item in the context menu is selected */
 @Override

     switch(item.getItemId()){
         case R.id.editBTN:
             Toast.makeText(getBaseContext(), "Selected Action1 ", Toast.LENGTH_LONG).show();
             mode.finish();  // Automatically exists the action mode, when the user selects this action
             break;
