如何从 MultiChoiceModeListener ActionMode 中隐藏后退按钮？

Question

我正在尝试从我们长按 Listview 项目时出现的上下文菜单中隐藏后退 button。我不知道如何访问 actionMode 菜单项，我试过 actionMode.getMenu().getItem() 但它没有显示后面的 button id。似乎 items 是这个菜单的默认项目，因为我从来没有给它充气。

这里是代码：

        _m_list_view.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) {
            _m_list_view.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
            _m_tweet_adaptateur.setChoiseMode(_m_list_view.getChoiceMode());
            _m_list_view.setItemChecked(i, true);
            return true;
        }
    });

    _m_list_view.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() {
        @Override
        public void onItemCheckedStateChanged(ActionMode actionMode, int i, long l, boolean b) {

            updateActionModeTitle(actionMode);
            if(_m_list_view.getCheckedItemCount()==0) {
                _m_list_view.setChoiceMode(ListView.CHOICE_MODE_NONE);
            }
        }

        @Override
        public boolean onCreateActionMode(ActionMode actionMode, Menu menu) {
            mActionModeIsActive = true;
            MenuInflater inflater = getMenuInflater();
            inflater.inflate(R.menu.context_menu_tweet, menu);
            actionMode.setCustomView(LayoutInflater.from(MainActivity.this).inflate(R.layout.menu_select_tweet, null));
            updateActionModeTitle(actionMode);
            return(true);
        }

        @Override
        public boolean onPrepareActionMode(ActionMode actionMode, Menu menu) {
            return false;
        }

        @Override
        public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem) {
            switch (menuItem.getItemId()) {
                //quand on appui sur ok dans le menu
                case R.id.item_select_multi_tweet:
                   //code when ok
                    }
                    return true;
                default:
                    return false;
            }
        }


        @Override
        public void onDestroyActionMode(ActionMode actionMode) {
            //_m_list_view.setChoiceMode(ListView.CHOICE_MODE_NONE);
            mActionModeIsActive = false;
            _m_tweet_adaptateur.setChoiseMode(_m_list_view.getChoiceMode());
            _m_list_view.setAdapter(_m_tweet_adaptateur);
        }
    });

我想要的只是delete/hide这一项：

谢谢！

我找到了解决方案，我只需要将一项 actionModeCloseButtonStyle 添加到 styles.xml 中：

    <!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="actionModeCloseButtonStyle">@style/NoCloseButtonActionModeStyle</item>
</style>

<style name="NoCloseButtonActionModeStyle">
    <item name="android:visibility">invisible</item>
</style>
