Android: error: Error parsing XML: not well-formed (invalid token)
提问by Marius
There's an error in my activity_main.xml on line 13 (Wich you can see below). It says "Error parsing XML: not well-formed(invalid token)". In addition to that my R.java has killed itself. I've found ways to fix it, but they won't work (At least I think it's because of that) until this error is fixed. Thanks for any help. Just by the way I'm following the tutorial on Javacodegeeks.com
我的 activity_main.xml 中的第 13 行有一个错误（您可以在下面看到）。它说“解析 XML 时出错：格式不正确（无效令牌）”。除此之外，我的 R.java 已经自杀了。我已经找到了修复它的方法，但在修复此错误之前它们将无法工作（至少我认为是因为这个）。感谢您的帮助。顺便说一下，我正在关注Javacodegeeks.com上的教程

Have you mixed the Java code in the activity_main.xml too? Because your activity_main.xml should only contain the following code:
您是否也在 activity_main.xml 中混合了 Java 代码？因为您的 activity_main.xml 应该只包含以下代码：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView android:id="@+id/listView"
android:layout_height="match_parent"
android:layout_width="match_parent"/>
</RelativeLayout>
And MainActivity.java should contain the following code:
而 MainActivity.java 应包含以下代码：
List<Map<String, String>> planetsList = new ArrayList<Map<String,String>>();
private void initList() {
planetsList.add(createPlanet("planet", "Mercury"));
planetsList.add(createPlanet("planet", "Venus"));
planetsList.add(createPlanet("planet", "Mars"));
planetsList.add(createPlanet("planet", "Jupiter"));
planetsList.add(createPlanet("planet", "Saturn"));
planetsList.add(createPlanet("planet", "Uranus"));
planetsList.add(createPlanet("planet", "Neptune"));
}
private HashMap<String, String> createPlanet(String key, String name) {
HashMap<String, String> planet = new HashMap<String, String>();
planet.put(key, name);
return planet;
}
I have just copied the code here from the link that you have provided.
我刚刚从您提供的链接中复制了此处的代码。

Remove your JavaCode from xml and put it in seperate java file you cannot put java code inside your xml file.
从 xml 中删除您的 JavaCode 并将其放在单独的 java 文件中，您不能将 java 代码放在 xml 文件中。
回答by jfv
Are you putting Java code inside the XML file? Java code goes inside a class file.
您是否将 Java 代码放入 XML 文件中？Java 代码位于类文件中。
According to that tutorial, they want you to create a xml file called activity_main.xmlwith contents
根据该教程，他们希望您创建一个名为activity_main.xml内容的 xml 文件
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView android:id="@+id/listView"
android:layout_height="match_parent"
android:layout_width="match_parent"/>
</RelativeLayout>
And separatelly, a java class called MainActivity.java
并且单独地，一个名为的 java 类 MainActivity.java
with contents
有内容
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// ....
}
//...
}

Remove Javacode inside XML tags
删除 XML 标签内的 Javacode
And
和
I think change it as
我认为将其更改为
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:mynamespace="http://schemas.android.com/apk/res/com.Learning.learning"

mynamespace:layout_height="success">
<ListView android:id="@+id/listView"
android:layout_height="match_parent"
android:layout_width="match_parent" />
</RelativeLayout> ^Listview tag closed here
Remove </ListView>tag. Because you are already closed at 12th line
移除</ListView>标签。因为你已经在第 12 行关门了

You have included java code in the XML file. Remember that Android uses XML files for layouts and resources definition only. Code for data poplulation, manipulation and other processing must be done in the java source files. For example, you can populate the list within you MainActivity.java file.
您已经在 XML 文件中包含了 java 代码。请记住，Android 仅将 XML 文件用于布局和资源定义。数据填充、操作和其他处理的代码必须在 java 源文件中完成。例如，您可以填充 MainActivity.java 文件中的列表。

You can't write your program code in your XML file. That is why you have an error. Read more about XML Layout
您不能在 XML 文件中编写程序代码。这就是为什么你有错误。阅读有关XML 布局的更多信息
