        super.onStart();
        ArrayAdapter<String> arrayAdapt=new ArrayAdapter<String>(getApplicationContext(),android.R.layout.simple_list_item_multiple_choice,xmlList);
        listView_xml.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
        listView_xml.setAdapter(arrayAdapt);
    }
}

我的 main.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
 <ListView 
    android:id="@+id/listView_xml" 
    android:layout_height="wrap_content" 
    android:layout_width="match_parent">
 </ListView>
</LinearLayout>

和我的 AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="BasicWebService.com"
      android:versionCode="1"

堆栈跟踪充满了 BasicWebServiceActivity.java 文件第 49 行抛出的 ClassCastExceptions。跟踪表明有问题的行位于 getListFromXML() 方法中。我将您的代码复制到文本编辑器中，对我来说，第 49 行是：

   NodeList nodeListText=( (Document) elementMain).getElementsByTagName("text");

Here you are Casting elements as Documents，这可能会导致问题

The stack trace is full of ClassCastExceptions getting thrown by line 49 of your BasicWebServiceActivity.java file. The trace indicates the offending line is in the getListFromXML() method. I copied your code into a text editor and for me line 49 was:

   NodeList nodeListText=( (Document) elementMain).getElementsByTagName("text");

Here you are casting elements as documents which is probably causing the problem

当元素不是文档的实例时，您正在将它们转换为文档。

NodeList nodeListText=( (Document) elementMain).getElementsByTagName("text");

NodeList nodeListValue=( (Document) elementMain).getElementsByTagName("value");

You are casting Element to Document when they are not instances of Document.

NodeList nodeListText=( (Document) elementMain).getElementsByTagName("text");

NodeList nodeListValue=( (Document) elementMain).getElementsByTagName("value");
