ActivityNotFoundException啓動清單中的類

我有一個主類啓動（或至少這是我想要發生的）兩個其他類的應用程序。主類WhenIGetToActivity啓動第一類CreateLoc，但沒有發生錯誤，但在嘗試啓動第二個Menu時拋出ActivityNotFoundException。ActivityNotFoundException啓動清單中的類

下面是從WhenIGetToActivity

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    Intent myIntent = new Intent(getApplicationContext(), Menu.class); 
    startActivity(myIntent); 
    return true; 
} 
... 

public boolean onTap(final GeoPoint p, final MapView mapView) { 
     boolean tapped = super.onTap(p, mapView); 
     if (tapped) { 
      Intent myIntent = new Intent(getApplicationContext(), CreateLoc.class); 
      startActivity(myIntent); 
     } else {

兩個次級類在正確的（和相同）封裝相關的代碼，既extends Activity。

這裏是我的清單文件

我曾嘗試清洗項目。

任何想法。

從4個回答，我改變類的名稱下面的建議，我已經在這樣做，現在所謂的StevesToolsMenu.class

新onCreateOptionsMenu現在有行：

Intent myIntent = new Intent(getApplicationContext(), StevesToolsMenu.class);

的相關部分清單文件是現在：

<application> 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" > 

    <uses-library android:name="com.google.android.maps" /> 

    <activity 
     android:name=".WhenIGetToActivity" 
     android:label="@string/app_name" 
     android:theme="@android:style/Theme.NoTitleBar" > 
     <intent-filter>

      <category android:name="android.intent.category.LAUNCHER" />

    <activity android:name=".StevesToolsMenu" >

我們似乎已經用另一個問題代替了一個問題（或者更確切地說，發現了第二個問題）。

無論從哪個角度來看，我仍然很難理解爲什麼一個類應該工作而另一個類（看起來是相同的方式安裝）沒有。

您試圖啓動一個名爲android.view.Menu的活動。您沒有名爲android.view.Menu的活動。你有一個活動，出於某種原因，被命名爲SandS.Geo.Cal.Menu。

意圖myIntent =新意圖（getApplicationContext（），Menu.class）;

如果更改Intent構造的Class對象的第二個參數爲您的活動，這可能會更好地工作。更好的辦法是不要有名爲Menu的活動，但要使用更具特色的活動，以幫助防止將來發生這種衝突。

我不確定你在這裏的意思。首先，這個活動被稱爲'SandS.Geo.Cal.Menu'，因爲我希望它被命名爲;我已將其更改爲'SandS.Geo.Cal.StevesToolsMenu'，以防止與View.Menu衝突。其次，如果你花時間看看，你會發現我的Intent構造函數的第二個參數是'Menu.class'（現在是'StevesToolsMenu.class'）。 –

@ steve.watson128：「其次，如果你花時間看看，你會看到我的Intent構造函數的第二個參數是Menu Menu。」 - 我*做*花時間看看。然而，你顯然沒有。您的錯誤消息是「無法找到明確的活動類{SandS.Geo.Cal/android.view.Menu}'。注意對'android.view.Menu'的引用。這是因爲你試圖啓動'android.view.Menu'作爲一個activity，因爲你的'Menu.class'引用解決了'android.view.Menu'，因爲你正在導入'android.view.Menu'和不是你自己的菜單類。 – CommonsWare

@ steve.watson128：關於您的新錯誤，「MapViews只能在MapActivity的實例中創建」是一個相當直接的錯誤消息。 Android認爲無論你在膨脹什麼佈局的第17行，都會引用'MapView'，並且你的'StevesToolMenu'不是'MapActivity'。如果您確信您的佈局未引用MapView，請嘗試清理項目（Eclipse中的項目> Clean或命令行開發中的ant clean），因爲偶爾Android的資源ID引用不同步。 – CommonsWare

我認爲問題在於Android庫中已經定義了一個Menu類。如果您嘗試打開「選項」菜單，則不會將其作爲另一項具有Intent的活動啓動。您可以編程方式創建一個Menu或從XML文件充氣一個Menu。

你說得對，但更改名稱並沒有解決問題。見上面修改的問題。 –

如何在AndroidManifest.xml

改變你的活動

老一

<activity android:name="CreateLoc" ></activity> 
<activity android:name="Menu" ></activity>

要

<activity android:name=".CreateLoc" ></activity> 
<activity android:name=".Menu" ></activity>

來源

2012-06-21 15:47:37 Hein

在這種情況下，它不起作用。另外，Eclipse本身也放入了「CreateLoc」條目，而不是點。無論如何，看上面修改的問題，它已經解決了這個問題。 –
