Change <code>&lt;item id="@+id/my_location"</code> to <code>&lt;item android:id="@+id/my_location"</code>. This in all three places.

Also, in here: <code>android:title:="Current location"</code> remove the colon after <code>title</code>.

create an XML file inside your project's <code>res/menu/</code> directory Not in in <code>res</code> folder 
&amp; 

dont forget to prefix the id attributes. 

Try like this:

<pre><code>&lt;?xml version="1.0" encoding= "utf-8"?&gt;
&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
 &lt;item android:id="@+id/my_location"

 android:title="Current location" /&gt;

 &lt;item android:id="@+id/mapview_satellite"
 android:icon="@drawable/satelliteview"
 android:title="Satellite View" /&gt;

 &lt;item android:id="@+id/mapview_normal"
 android:icon="@drawable/normalview"
 android:title="Normal view" /&gt;
&lt;/menu&gt;

blocks|key|204664|text|有时，XML代码可能会被正确编写，因此您只需剪切当前已有的内容，然后将其从行号中删除，然后重新粘贴它，错误就应该得到修复。如果没有，那么你就知道你的代码是错的。xml的默认设置是识别您首先放入的内容，并且需要删除这些内容才能重新开始。相信我，我刚刚花了3天的时间来解决这个问题，并且完全按照上面说的那样做了，祝你好运。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|204665|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Some times the XML code might be written correctly so you need to simply cut what you currently have and then delete it from the line numbers then re-paste it and the error should be fixed. If it doesn't then you know your code is wrong. The xml default is to recognize what you have put at first and needs to be removed in order to begin again. Trust me I just spent 3 days on that very problem and did exactly what is said above, good luck.

Adding android: before the attribute solved my problem.

blocks|key|200139|text|信不信由你，对于任何试图在下载的书中使用示例的人来说，你可能需要确保你有真正的引号，因为编译器能理解它们。我收到了与OP相同的错误，以及许多类似的解析错误，因为我试图以较小的方式修改XML文件。然后，我注意到粘贴的代码片段中的引号与我键盘上的不同(在代码片段中，它们向右倾斜，如果我自己键入它们，它们是上下笔直的)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|200140|我知道这听起来很疯狂，我自己也很难相信，但当我重新输入我的语录时，它工作得很好。|200141|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Believe it or not, for anyone who tries to work through examples in downloaded books, you may need to make sure you have true quotation marks as the compiler understands them. I'd been getting the same error as the OP, and many similar parse errors as I tried to modify an XML file in small ways. I noticed then that quote marks from the pasted code snippets were different from the ones on my keyboard (in the snippets they leaned to the right, and if I typed them myself they were straight up and down). 

I know this sounds nuts and I could hardly believe it myself, but when I retyped my quotes it worked fine.

blocks|key|2835167|text|您还需要确保以下两行位于属性列表中：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2835168|xmlns:android="http://schemas.android.com/apk/res/android"

You also need to make sure the following two lines are in your attributes list:

<pre><code>xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

If you omit those, Eclipse will just give you the "missing android prefix" error.
