这是我下面的代码，它从服务器获取 xml 响应我如何在这段代码中设置请求超时计时器？如果服务器没有响应我的应用程序返回异常我是否在下面的代码中设置计时器所以如果服务器在 15 秒异常调用中没有响应
public static String[][] AgAppXMLParser( String parUrl) {
String _node,_element;
String[][] xmlRespone = null;
try {
String url = www.xyz.com;
URL finalUrl = new URL(url);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(finalUrl.openStream()));
doc.getDocumentElement().normalize();
NodeList list=doc.getElementsByTagName("*");
_node=new String();
_element = new String();
xmlRespone = new String[list.getLength()][2];
//this "for" loop is used to parse through the
//XML document and extract all elements and their
//value, so they can be displayed on the device
for (int i=0;i<list.getLength();i++)
{
Node value=list.item(i). getChildNodes().item(0);
_node=list.item(i).getNodeName();
_element=value.getNodeValue();
xmlRespone[i][0] = _node;
xmlRespone[i][1] = _element;
}//end for
}//end try
catch (Exception e)
{
flag=false;
Log.e(LOG_TAG, "CONNECTION ERROR SERVER NOT RESPONDING", e);
}
return xmlRespone;
}
