I'm new to Android want to read a XML-file and write the content into a ListView
The XML Parser must be the problem. I hope it is only a little mistake in my code.
orderxml2.xml
<?xml version="1.0"?>
<order>
<item id="1">
<title>BiTest1</title>
<group>G1</group>
<price>5.00</price>
<description>Example</description>
</item>
<item id="2">
<title>Test2</title>
<group>g1</group>
<price>2.00</price>
<description>Example</description>
</item>
</order>
The Parser
public class Order extends Activity
{
private String[] lv_arr = {};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.order);
try {
ArrayList<String> orderxmlarray = PrepareListFromXml();
lv_arr = (String[]) orderxmlarray.toArray(new String[0]);
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
ListView lv = (ListView) findViewById(R.id.listViewOrder1);
lv.setAdap开发者_JAVA技巧ter(new ArrayAdapter<String>(Order.this, android.R.layout.simple_list_item_1, lv_arr));
}
public ArrayList<String> PrepareListFromXml() throws XmlPullParserException, IOException
{
ArrayList<String> orderItems = new ArrayList<String>();
XmlResourceParser orderxml = getResources().getXml(R.xml.orderxml2);
orderxml.next();
int eventType = orderxml.getEventType();
while (eventType != XmlResourceParser.END_DOCUMENT)
{
if (eventType == XmlResourceParser.START_DOCUMENT) {
orderItems.add(orderxml.getAttributeValue(null, "title"));
}
else if(eventType == XmlResourceParser.END_DOCUMENT) {
orderItems.add(orderxml.getAttributeValue(null, "title"));
}
try {
eventType = orderxml.next();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return orderItems;
}
}
I think, you can visit this site http://www.ibm.com/developerworks/opensource/library/x-android/ . Read section Easier SAX parsing, I think that the solution presented there would be better than what you have right know, definitely less error prone.
My working code:
while (eventType != XmlPullParser.END_DOCUMENT) {
if (eventType == XmlPullParser.START_TAG) {
if (orderParser.getName().equalsIgnoreCase("title")) {
orderItems.add(orderParser.nextText());
}
}
