我的xmlHandler code低于
My xmlHandler code is below
import java.util.ArrayList;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
import android.util.Log;
import com.bvbi.invoicing.client.android.customer.model.CustomerPojoInList;
public class CustomerListParser extends DefaultHandler {
Boolean currentElement = false;
String tempValue = null;
CustomerPojoInList customer = null;
public static ArrayList<CustomerPojoInList> customers = null;
@Override
public void startDocument() throws SAXException {
customers = new ArrayList<CustomerPojoInList>();
}
/** Called when tag starts ( ex:- <name>AndroidPeople</name>
* -- <name> )*/
@Override
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
currentElement = true;
if (localName.equals("Customer"))
{
/** Start */
customer = new CustomerPojoInList();
}
}
/** Called when tag closing */
@Override
public void endElement(String uri, String localName, String qName)
throws SAXException {
currentElement = false;
String currentValue = tempValue;
tempValue = "";
/** set value */
if (localName.equalsIgnoreCase("customerId"))
customer.setCustomerId(currentValue.toString());
else if (localName.equalsIgnoreCase("customerFname"))
customer.setCustomerFname(currentValue.toString());
else if (localName.equalsIgnoreCase("customerLname"))
customer.setCustomerLname(currentValue.toString());
else if (localName.equalsIgnoreCase("customerImage"))
{
Log.d("prabhu","Customer image in parser......"+currentValue);
customer.setCustomerImage(currentValue.toString());
}
else if (localName.equalsIgnoreCase("Customer"))
customers.add(customer);
}
/** Called to get tag characters */
@Override
public void characters(char[] ch, int start, int length)
throws SAXException {
if (currentElement) {
tempValue = new String(ch,start, length);
if(tempValue.equals(null))
tempValue = "";
currentElement = false;
}
}
@Override
public void endDocument() throws SAXException {
}
}
请帮我解决这个问题。
推荐答案
在SAX解析器,字符()方法只分析每次最多1024个字符。因此,我们需要追加的字符串,直到所有的字符被解析。
In sax parser, characters() method parses only maximum of 1024 characters each time. So we need to append the strings until all the characters are parsed.
我改变了上面的code如下:
I changed the above code as follows
public void characters(char[] ch, int start, int length)
throws SAXException
{
Log.d("prabhu","Customer image length in parser......"+length);
if (currentElement ) {
tempValue = new String(ch,start, length);
if(tempValue.equals(null))
tempValue = "";
}
tempValue = tempValue+new String(ch,start, length);
}
