错误@Override片段中的方法被调用（Android）

问题描述：

我有一个使用片段的问题。
首先是一些基本的信息。我正在使用带3个Tabs/Fragments的Actionbar（support.v4）。前两个片段会导致问题。第一个片段扩展了ListFragment，第二个扩展了片段。两者都有一个ListView和一个ArrayAdapter（不同的ArrayAdapters）。错误@Override片段中的方法被调用（Android）

我的片段：

在两个片段我创建了一个ContextMenu（不同的菜单/的菜单项）：

在两个片段我重写onCreateContextMenu(..)和onContextItemSelected(..)。
我的适配器：

两个适配器重写getView方法。
- 如果我选择片段2的ContextItem，frament 1的onContextItemSelected方法被称为：
- 我的问题。
- 如果我更新片段2，也调用片段1的getView。

有了您的帮助和StackOverflow的我已经发现，如果一个片段是活跃的两个片段直接在它旁边是已经激活。因此，如果两个片段具有相同的可覆盖方法，则将选择第一个片段。问题是，我没有找到解决方案;-)

有人在这里，谁了解我的问题和/或曾经处理过吗？

发布一些代码，您提出，我们会尽力帮助你们。但现在，这很困难。 – Fllo

你使用viewpager来保存片段？ –

是的，我喜欢。因为圣诞节我没有那么多时间。但我会尽快写一些代码。非常感谢！ – Wicked161089

答

的Android FragmentManager通过所有碎片迭代处理针对的ContextMenuItem选择覆盖，让您的每一个片段处理上下文菜单中点击需要有逻辑，是否处理呼叫或者如果该呼叫应该传递给下一个片段。
