Question

我有一个片段，我正试图通过按钮点击这样开始另一个活动：

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

应用程序在startActivity(i)的{{1}}来电时崩溃。这是logcat：

Fatal Exception

这是我的清单文件：

奇怪的是我有另一个应用程序，它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？

你的清单中拼错了。您有：android:name="com.wilk.android.tablink.RoundPagerAcivity"它应该是android:name="com.wilk.android.tablink.RoundPagerActivity"。

另外，我不知道这是否重要，但在我的应用程序中，我也有“详细”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>

从fragment启动时无法找到显式活动类
