ActivityNotFound异常抛出在AndroidManifest.xml中列出的preferenceActivity

问题描述

我想一个preference屏幕添加到我的应用程序。

I'm trying to add a Preference screen to my app.

preferences.java：

 public class Preferences extends PreferenceActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.layout.preferences);
    }
 }

preferences.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
  xmlns:android="http://schemas.android.com/apk/res/android">
  <PreferenceCategory
    android:title="General Settings">
    <RingtonePreference
        android:name="Ringtone"
        android:summary="Select a Ringtone for recieved messages"
        android:title="Rington"
        android:key="ringtonPref" />
  </PreferenceCategory>
  <PreferenceCategory
    android:title="Account Settings">
        <Preference
            android:title="Sign Out"
            android:summary="Sign out of current account"
            androidKey="signOut" />
    </PreferenceCategory>
</PreferenceScreen>

和的Andr​​oidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="steamanywhere.com"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon"
                 android:label="@string/app_name"
                 android:theme="@android:style/Theme.NoTitleBar"
                 android:debuggable="true">
        <activity android:name=".SteamAnywhere"
                  android:label="@string/app_name">

        </activity>

        <acitivity android:name="steamanywhere.com.Preferences" >
        </acitivity>
        <activity android:name=".StartupScreen" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <service android:enabled="true" android:name=".WebEventListener" />
    </application>
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>

</manifest>

在preferences活动开始SteamAnywhere.java具有以下code：

The Preferences activity is started in SteamAnywhere.java with the following code:

Intent preferenceIntent = new Intent(this, steamanywhere.com.Preferences.class);
startActivity(preferenceIntent);

在 startActivity（preferenceIntent）; 我得到了以下异常：

android.content.ActivityNotFoundException: Unable to find explicit activity class {steamanywhere.com/steamanywhere.com.Preferences}; have you declared this activity in your AndroidManifest.xml?

但声明..任何想法？

But it is declared.. Any ideas?

我已经经历了许多类似的问题，但看着没有回答的为我工作。

I've looked through many similar questions but none of the answers work for me.

推荐答案

我想答案可能是在XML

I think the answer may be in your xml

<acitivity android:name="steamanywhere.com.Preferences" >
</acitivity>

您已经拼活动错了。

<activity android:name="steamanywhere.com.Preferences" >
</activity>

另外，你为什么不刚才说什么？

Also, why do you not just say?

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