我們無法根據片段

Question

開始時，我有我試圖從一個點擊按鈕這樣再掀活性的片段，以找到明確的活動類：

Intent i = new Intent(getActivity(), RoundPagerActivity.class); 
// put extras 
startActivity(i); 

與通話中的應用程序崩潰到startActivity(i)一個Fatal Exception。這裏的logcat的：

這裏是我的清單文件：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.wilk.android.tablink" 
    android:versionCode="1" 
    android:versionName="1.0" >

     android:minSdkVersion="8" 
     android:targetSdkVersion="17" /> 

    <uses-permission android:name="android.permission.INTERNET" /> 
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 

    <application 
     android:allowBackup="true" 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@android:style/Theme.Holo" > 

     <!-- other activities --> 

     <!-- activity that calls the pager activity --> 
     <activity 
      android:name="com.wilk.android.tablink.RoundListActivity" 
      android:label="@string/app_name" > 

     </activity> 

     <!-- activity that is called --> 
     <activity 
      android:name="com.wilk.android.tablink.RoundPagerAcivity" 
      android:label="@string/app_name" > 
      <meta-data 
       android:name="android.support.PARENT_ACTIVITY" 
       android:value="com.wilk.android.tablink.RoundListActivity" /> 

     </activity> 

    </application> 

</manifest> 

奇怪的是我還有一個應用程序，這是否完全相同的方式W/O問題。 我在這裏看過其他的問題，我很確定我已經用盡了這些選擇，至少那些似乎適用的選項。我試圖在新活動中設置中斷點，但沒有一個被擊中。任何人都可以看到我新近忽略的東西嗎？

Answer 1

它在您的艙單中拼寫錯誤。您有：android:name="com.wilk.android.tablink.RoundPagerAcivity"它應該是android:name="com.wilk.android.tablink.RoundPagerActivity"。

另外，我不知道它的問題，但在我的應用程序也有一個屬性上這樣的「細節」活動：

<activity 
     android:name="com.wilk.android.tablink.RoundPagerActivity" 
     android:label="@string/app_name" 
     android:parentActivityName="com.wilk.android.tablink.RoundListActivity"> 
     <meta-data 
      android:name="android.support.PARENT_ACTIVITY" 
      android:value="com.wilk.android.tablink.RoundListActivity" /> 
    </activity>
