如何在android中的gridview行中安排Cust_Name，Order_No，Freight_Rate等.. ..

這是確切的鏈接，上述XML文件

「http://54.251.60.177/StudentWebService/StudentDetail.asmx/GetTMSOrders」

源頭參考

// All static variables

    ArrayList<HashMap<String, String>> menuItems = 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(KEY_TABLE); 

    // looping through all item nodes <item> 

    for (int i = 0; i < nl.getLength(); i++) 
    { 
     // 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(KEY_CUST, parser.getValue(e, KEY_CUST)); 
     map.put(KEY_ORDER, parser.getValue(e, KEY_ORDER)); 
     map.put(KEY_FREIGHT,parser.getValue(e, KEY_FREIGHT)); 

     // adding HashList to ArrayList
