Android-在选项卡活动中更新片段

我正在构建一个带有tab活动的android应用程序。 选项卡将列出当用户触发长按事件时 在列表中确定的项目中，将显示上下文菜单 将被打开，用户将能够选择该选项 编辑该项目

为此，我创建了一个Activity，它扩展了FragmentActivity并实现了ActionBar.TabListener

我需要做的是，当用户选择编辑项目的选项时，表单会在该列表的选项卡（fragmentlist）内打开，更新当前选项卡的片段。 我尝试在列表活动片段中使用FragmentTransaction，但没有成功

我尝试的代码如下（在ListFragment处）

有人能帮我吗？谢谢

编辑： FragmentActivity的布局如下所示：

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"

您能再解释一下吗？列表在哪里？您需要在哪里显示表格？选项卡包含什么？我编辑了问题并添加了相关代码。您必须将该项目设置为viewPager，例如：viewPager.setCurrentItem（tab.getPosition（））在OnAbsSelected（）中。试试这个，让我知道。我试过了，但没有任何改变：（只是把你发布的代码放进去了吗？你有没有收到任何错误？或者这样行吗？
