从fragment启动时无法找到显式活动类

Question

我有一个片段,我试图从按钮单击开始另一个活动,如下所示:

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

该应用程序在通话时崩溃startActivity(i)了Fatal Exception.这是logcat:

这是我的清单文件:

<?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" >

    <uses-sdk
        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>

奇怪的是我有另一个应用程序以同样的方式执行此操作.我在这里看了其他问题,我很确定我已经用尽了那些选择,至少那些似乎适用的选择.我试图在新活动中设置断点但没有被击中.任何人都可以看到我新近被忽视的东西吗？

Answer 1

它在你的清单中拼写错误.你有:android:name="com.wilk.android.tablink.RoundPagerAcivity"它应该是android:name="com.wilk.android.tablink.RoundPagerActivity".

另外,我不知道它是否重要,但在我的应用程序中,我还有一个关于"细节"活动的属性,如下所示:

    <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>
