我有一个主菜单，上面有一张图片，上面写着水平选择菜单。一旦你通过主菜单并继续选择一个级别它崩溃并给出这个错误。我用与主菜单中完全相同的方式制作了意图。任何人都能帮我弄清楚为什么会一直崩溃？

答案 0 :(得分：0)
根据您的logcat错误，它清楚地表明您错过了AndroidManifest文件中的活动声明。
请在清单文件中声明您的活动，如下所示：
<application android:label="@string/app_name" <activity android:name="com.christianalvarez.justriddles.Level1" android:label="@string/app_name" > </application>
答案 1 :(得分：-1)
好像你没有在android清单文件中为此活动添加活动标签。您需要为androidmanifest文件中的每个活动添加一个活动标记。
