出于某种原因，在我的调试器中打开了一个新选项卡，标题为：Activity.class标题说明:Class File Editor和错误说明: The JAR file c:\sdk\platforms\android-17\android.jar has no source attachment。您可以通过单击下面的附加源来附加源。

从那里我尝试从我的工作区添加它，但它仍然不起作用（它只是说现在更改附加源）

尝试关注

第 1 步：转到 adroid-sdk 安装文件夹。确保您有一个文件夹android-17，位于android-sdk/sources/

第2步：现在去Class File Editor tab。在那里你会看到一个带有标签的按钮'Attach source code'。单击它并获得选择外部文件夹的选项。并浏览直到你到达上面提到的 android-17 文件夹。选择它。它将附上源代码。

第 3 步：现在刷新项目。

第 4 步：现在再次检查Activityby的源代码ctrl+click.

就是这样，现在你可以看到Activity.

更新：

参考附上android源码

我不确定附加正确 Android 源的最简单方法，但 eclipse 尝试打开 Activity.class 的原因可能是发生了一些异常。

看看logcat。您应该能够在那里看到堆栈跟踪并找到原因，甚至不需要 Android 源代码。

发生这种情况是因为您快到了方法的末尾onCreate。然后控制返回到Activity调用您的onCreate方法的类。如果您稍后尝试在应用程序中调试某些内容，则应稍后在代码中设置断点。然而，一旦你完成了你的onCreate方法，你就真的没有什么可以调试的了。如果您想调试实际的 AndroidActivity类，您需要下载源代码并告诉 eclipse 在哪里可以找到它，尽管我怀疑这不是您想要做的。
