我有一個應用程序有2個活動，主要活動（HomeActivity）有一個列表與不同對象的信息，我可以點擊這個對象和一個警報對話框將會出現，可以啓動我的第二個活動（ServerConfig），它將顯示所選對象的信息以及其他一些功能，現在問題在於，當我編譯該項目並將其稱爲第一個活動時魅力，但如果我回去，然後選擇列表上的相同或其他對象，並調用這個Activity ServerConfig，它會加載並顯示新的信息，但我放在底部的按鈕不再工作，他們只是什麼都不做，這個按鈕是單獨的，但另一個LinearLayout上的按鈕工作得很好。這個應用程序的服務告訴我，當我點擊按鈕時發送了這個工作，但是沒有任何更改。安卓系統 - 當我第二次致電活動時按鈕不工作
這裏是文件：
ServerConfig活動的XML。

沒有人會讀這樣一個胖的問題。如果他也讀了他會感到困惑。用緊湊的代碼或其中的一部分提供Short，Working和Compact問題更好 – mustangDC
