ListView标记在Contextual ActionBar中onItemLongClick上的选定列表条目

Question

我已经在主要详细信息视图中实现了ListView：onItemClick()根据列表项调用新的Activity详细信息。

onItemLongClick调用ActionMode.Callback以提供多个列表项的选择。我已经解决了问题，以避免在onItemClick()中返回true时选择项目时调用onItemLongClick()。

问题是在我点击一个项目并从活动中返回后，选择被显示/可视化。

请不要使用标准listSelector。我不确定这是否是正确的方法/解决方案。我尝试实现自定义listSelector，但它无法正常工作。

有什么建议吗？

ListView的XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".ResultFragment" >

    <!-- standard list_selector_background -->
    <ListView
        android:id="@+id/fragment_ergebnis_listView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:choiceMode="multipleChoice"
        android:divider="@color/gray_3"
        android:dividerHeight="1dp"
        android:listSelector="@android:drawable/list_selector_background"
        android:saveEnabled="true" >
    </ListView>
</LinearLayout>
