我在應用程序中出現了一些關於物理菜單按鈕的奇怪，不一致的行爲。物理菜單/溢出按鈕在某些視圖中無響應
以下可能會有幫助或可能沒有幫助： 我有一個應用程序，根據設備+屏幕大小+方向更改其UI的應用程序。在橫向平板電腦上，我使用同時查看2個片段的活動（聯繫人列表+所選聯繫人的聊天）。在手機上，在平板電腦上縱向擺放，我改用兩項獨立的活動;一個用於聯繫人列表，一個用於聊天。
我提到這一點是因爲我觀察到以下奇怪行爲：手機和平板電腦縱向方向上，我設備上的物理菜單按鈕在我的應用程序中沒有反應。當平板電腦處於橫向模式時，物理按鈕按預期工作（顯示我的操作欄的溢出菜單）。菜單按鈕在我的應用程序外正常工作。
我原本以爲問題出在我手機的android版本上，但考慮到我在縱向上也看到了平板電腦的問題，我不確定問題出在哪裏。我沒有硬編碼物理菜單按鈕的任何代碼，所以它不應該是一些功能不適合手機和麪向肖像的平板電腦的單窗格視圖複製。
任何想法或答案將不勝感激！ 謝謝
編輯：添加了要求的代碼。

我也有片段和片段xml的代碼，這也可能對你有用，但片段代碼非常大。我認識到，該活動的XML不是很有幫助，但沒有休息。讓我知道還有什麼可以幫助的，我會找出更好的分享方式。
你可以發佈你的菜單xml嗎？ – petey 2014-12-01 20:27:16
，併發布在縱向定位活動中添加xml的代碼。 – petey 2014-12-01 20:31:41
我添加了肖像取向活動代碼和它的xml。我沒有特定的menu.xml文件，每個活動和片段都有xml文件，我想他們會根據需要傳遞。對不起，如果它沒有幫助，讓我知道我還能提供什麼。 – gabe3vino 2014-12-02 16:30:06
