Android - 可检查的上下文菜单不起作用

Question

这是准备代码：

@Override
public void onCreateContextMenu(ContextMenu menu, View v,
                                ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);

    MenuInflater inflater = getActivity().getMenuInflater();
    inflater.inflate(R.menu.language_menu, menu);

    MenuItem menuItem = menu.findItem(R.id.arabic);
    if (UtilityPreferenceManager.getSelectedLanguage() == UtilityPreferenceManager.LanguageArabic) {
        menuItem.setChecked(true);
    } else {
        menuItem.setChecked(false);
    }

    menuItem = menu.findItem(R.id.english);

    if (UtilityPreferenceManager.getSelectedLanguage() == UtilityPreferenceManager.LanguageEnglish) {
        menuItem.setChecked(true);
    } else {
        menuItem.setChecked(false);
    }
}

@Override
public boolean onContextItemSelected(MenuItem item) {
    item.setChecked(true);
     switch (item.getItemId()) {
        case R.id.arabic:
            if (UtilityPreferenceManager.getSelectedLanguage() != UtilityPreferenceManager.LanguageArabic) UtilityPreferenceManager.changeLanguage(); 
            return true;

        case R.id.english:
            if (UtilityPreferenceManager.getSelectedLanguage() != UtilityPreferenceManager.LanguageEnglish) UtilityPreferenceManager.changeLanguage(); 
            return true;

        default:
            return super.onContextItemSelected(item);
    }
}

，这是菜单xml：

<group android:checkableBehavior="single">
    <item android:id="@+id/arabic"
          android:title="@string/arabic" />

    <item android:id="@+id/english"
          android:title="@string/english" />

</group>

问题是菜单始终显示为选择了英语。我确信语言首选项在首选项中正确保存。事实上，if条件工作正常，但似乎在完成onCreateContextMenu

后覆盖所选菜单项的内容
