我是一個非常沮喪newbee！ 我真的不知道從哪裏開始。我有一個基於傻瓜書中的應用程序的應用程序。得到它的工作。然後嘗試將其轉換爲使用時間和日期的WIMMOne對話框。在一堆錯誤的開始之後，我加載了其中一個樣本並使其工作。然後我將代碼分離出來並粘貼到我的示例中。我無法過去的錯誤。 （這不利於日食不斷增加了一些它自己。有時我加載源和所有報表，包括進口，被標記爲錯誤，有時我得到的R.id，---錯誤，我甚至有它標誌着註釋爲錯誤。收到編譯錯誤，我不uderstand
不過，我已經洗乾淨，並重新加載它足夠的時間，我覺得我到幾個真正的錯誤。
有地雷和示例代碼之間的一對夫婦的基本區別： 樣本是一個大的活動的java文件，礦是一個片段礦，在當時對話框一個單獨的Java文件中的樣品是在一個文件中，所以我編寫我的這種方式礦有兩個菜單，列表。用戶從中進入「詳細」菜單。樣品全部爲一個屏幕。
共有來自WIMM 2個JAR文件，我在庫兼得。
爲了節省空間，我包括了第一部分，我得到了3個錯誤，但如果需要的話，我會很樂意提供。
首先是樣品。它的工作原理，甚至與我的註釋代碼，沒有編譯錯誤： 謝謝，克拉克

錯誤消息表明您嘗試調用不存在的類上的方法。在示例代碼中，名爲_setContentView（）_的方法是類_MedicationsActivity_的一部分，該類擴展了_LauncherActivity_（可擴展_Activity_）。也許你的類應該_擴展_Activity _...，儘管每個類只能在Java中擴展一個類。 – jahroy
