你最有可能忘记什么。

<activity

    </activity>

将以下代码复制并粘贴到清单中。

使用此方法只需为应用程序添加名称。

        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"

导航到项目目录中的 AndroidManifest.xml 文件。将这条线放在<application></application>标签之间（其中应该有类似的东西）。

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