java - 启动 list 中的类时出现 ActivityNotFoundException

标签 java android android-intent android-manifest

我有一个应用程序，其主类启动了(或者至少这是我想要发生的)另外两个类。主类 WhenIGetToActivity 启动第一个类 CreateLoc 时没有错误，但在尝试启动第二个 Menu 时抛出 ActivityNotFoundException。

以下是WhenIGetToActivity中的相关代码

@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 {

两个辅助类都位于正确(且相同)的包中，都扩展 Activity。

这是我的 list 文件

<?xml version="1.0" encoding="utf-8"?>

我尝试过清理项目。

任何想法。

根据 4 个答案的建议，我更改了类的名称，我现在将其命名为 StevesToolsMenu.class

新的 onCreateOptionsMenu 现在包含以下行:

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

list 文件的相关部分现在是:

<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>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".CreateLoc" >
    </activity>
    <activity android:name=".StevesToolsMenu" >
    </activity>
</application>

我们似乎已经用一个问题替换了另一个问题(或者更确切地说发现了第二个问题)。

无论您以哪种方式看待它，我仍然很难理解为什么一个类应该工作而另一个(以看似相同的方式设置)类却不能。

最佳答案

旧的

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

至

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