Android應用程序不會運行

請幫我理解爲什麼我的應用程序未運行。我想檢查滑動是否有效，但它甚至不會在模擬器上啓動。由於我對編程非常陌生，因爲沒有編譯錯誤，所以我找不到有什麼問題。Android應用程序不會運行

如果它崩潰，你需要找到和職位時，你得到錯誤顯示的logcat的消息。它應該是一些10-50線堆棧跟蹤。 – Tim

你是否真的希望有人能夠篩選出所有這些，並猜測你所得到的編譯器錯誤？如果您要複製並粘貼整個應用程序的源代碼，那麼您至少可以爲我們提供堆棧跟蹤，對預期行爲與您所得行爲的解釋等。 –

我只檢查了幾行代碼，但我注意到，你是不要撥打super.onCreate()（和您的onCreate方法應該是不publicprotected）：

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main);

未能調用super.onCreate()拋出一個SuperNotCalledException。從onCreate文檔：

派生類必須通過打電話給超類的這個方法的實現。如果他們不這樣做，就會拋出異常。

如果您仍然需要幫助，則需要發佈新的LogCat錯誤。

在主要活動改變"public abstract class mainActivity"到"public class mainActivity" 然後換"protected void onCreate"到"public void onCreate。你還應該包括"super.onCreate(savedInstanceState);"在主activity.Guess中的onCreate類應該只是罰款。

嗨，我已經改變了代碼由薩姆和Mungaih的建議。我已將CatLog添加到帖子中，因爲對我來說沒有任何變化。所以我一定還在做錯事。 RG，埃裏克 – Eric

@Eric - 我沒有看到在您的文章中logcat中，請確保您添加它。 – Tim

我設法讓它工作。問題是手勢檢測器的東西。它甚至沒有調用類，我已經刪除了兩個，並使用TouchListener方法。

它現在刷卡，但只有一次，所以不是完全固定的，但要真的... :-)
