Question

我正在创建SOAP xml解析ListView。

我正在添加（ksoap2-android-assembly-2.6.2-jar-with-dependencies.jar）jar文件。

我也添加了权限（）

我正在使用ArrayList。

我不理解这个错误请帮帮我

MainActivity.java

Answer 1

您在主线上进行网络通话。

当应用程序尝试在其主线程上执行网络操作时， NetworkOnMainThreadException 抛出。

仅针对Honeycomb SDK或更高版本的应用程序进行此操作。针对早期SDK版本的应用程序可以在其主要事件循环线程上进行联网，但是非常不鼓励。

http://android-developers.blogspot.in/2009/05/painless-threading.html。我建议您查看链接中的文章。

使用Asynctask发出soap请求。

在您的活动中

public class MainActivity extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); new SoaprequestTask().execute(); } private class SoapRequestTask extends AsyncTask<Void, Void, Void> { //runs on ui thread. protected void onPreExecute() { //display progressdialog } // runs in the background thread. do not update ui from here protected Void doInBackground(Void... params) { //make a soap request here SoapObject request=new SoapObject(NAMESPACE, METHOD_NAME); request.addProperty("bSelected", true); SoapSerializationEnvelope sse=new SoapSerializationEnvelope(SoapEnvelope.VER11); sse.setOutputSoapObject(request); sse.dotNet=true; HttpTransportSE htse=new HttpTransportSE(URL); try { htse.call(SOAP_ACTION, sse); } catch (IOException e) { e.printStackTrace(); } catch (XmlPullParserException e) { e.printStackTrace(); } SoapObject res=(SoapObject) sse.bodyIn; final ArrayList<HashMap<String, String>> valuesList = new ArrayList<HashMap<String, String>>(); XMLParser parser = new XMLParser(); String xml = parser.getXmlFromUrl(URL); // getting XML Document doc = parser.getDomElement(xml); // getting DOM element NodeList nl = doc.getElementsByTagName(FORMMODEL); // looping through all item nodes <item> for (int i = 0; i < ((SoapObject) nl).getPropertyCount(); i++) { SoapObject namesObject = (SoapObject) res.getProperty(i); for(int j=0;j<namesObject.getPropertyCount();j++) { Object objectNames=namesObject.getProperty(j); SoapObject soapObjectText1 = (SoapObject)objectNames; SoapObject soapObjectText2 = (SoapObject)objectNames; SoapObject soapObjectText3 = (SoapObject)objectNames; String sText1 = soapObjectText1.getProperty("iText1").toString(); String sText2 = soapObjectText2.getProperty("sText2").toString(); String sText3 = soapObjectText3.getProperty("sText3").toString(); // creating new HashMap HashMap<String, String> map = new HashMap<String, String>(); Element e = (Element) nl.item(i); // adding each child node to HashMap key => value map.put(TEXT1, parser.getValue(e, sText1)); map.put(TEXT2, parser.getValue(e, sText2)); map.put(TEXT3, parser.getValue(e, sText3)); System.out.println("MY SOAP RESPONE IS"+ res.getProperty(0).toString()); // adding HashList to ArrayList valuesList.add(map); } return null; } //runs on ui thread.update ui here protected void onPostExecute(Void params) { //dismiss progress dialog and update ui. display data in listview } } }

我刚从您的问题中粘贴了上述代码。确保不要对ui doInBackground（）进行更改。在onPostExecute（）;
中显示listview中的内容
查看标题The 4 Steps

您也可以使用robopsice 。 https://github.com/octo-online/robospice

Answer 2

您正在尝试在UI线程上发出请求。将在UI线程上调用onCreate()方法，并且始终不鼓励执行这样的长操作，并且从Honeycomb（我相信）尝试这样做现在将抛出异常。

您可能希望在this question中使用Android上的线程中的某些资源。
