Im parsing an xml file and i keep getting a nullpointer exception. I don't know here the null pointer is :(

list.setAdapter(adapter);
list.setOnItemClickListener(new OnItemClickListener() {

in.putExtra(KEY_FILESIZE, filesize);
in.putExtra(KEY_THUMB_URL, thumburl);
in.putExtra(KEY_DOCUMENT_URL, doc_url);
startActivity(in);
}
});
}
}
i only started getting the nullpointer excepetion after i added the preference variable
Put the SharedPreferences line into you onCreate() method.
Also you need to use if(){//do something} else {//do something else}
SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(this);
if(sharedPrefs.getBoolean("french", false))
{
URL="https://dl.dropbox.com/u/######/wosm-library-EN.xml";
}
else
{
URL="https://dl.dropbox.com/u/######/wosm-library-FR.xml";
}
A far better way to do this would be to use a resource string for the Dropbox URL and provide different localizations. Then you would not need this code at all.

the error in line 38 or line i was give (*) this mark...
pleas help me...
If the nullpointer is coming up on below line (with *):
(*) NodeList nl = doc.getElementsByTagName(KEY_ITEM); //i reckon the nullpointer is coming up on the doc object...
Then I reckon to check whether the xml which is being retrieved from the getXMLFromURL method
is correct?:
XMLParser parser = new XMLParser();
String xml = parser.getXMLFromURL(URL); // getting XML (Is this correctly retreived?
Document doc = parser.getDomElem(xml); // getting DOM element (This is returning null)
For more help share your XMLParser class
You need to use a Thread or AsyncTask to perform the "Networking Operations". Otherwise you will get NetworkOnMainThreadException. read this
Add permission to AndroidManifest.xml.
<uses-permission android:name="android.permission.INTERNET"/>
An example using a Thread
menuItems = new ArrayList<HashMap<String, String>>();
final XMLParser parser = new XMLParser();
Thread th = new Thread(new Runnable() {
#Override
public void run() {
xml = parser.getXmlFromUrl(URL);
handler.post(new Runnable() { //create an object of Handler class in onCreate() - (android.os.Handler)
#Override
public void run() {
Document doc = parser.getDomElement(xml);
nl =doc.getElementsByTagName(KEY_ITEM);
//other code inside onCreate() - for loop
}
});
}
}
th.start();
SimpleAdapter adapter = new SimpleAdapter(this, menuItems, R.layout.list_item,
new String[]{KEY_NAME, KEY_COST, KEY_DESCRIPTION}, new int[]{R.id.name, R.id.cost, R.id.description});
setListAdapter(adapter);

I have a big xml file(Around 100+ Items), how do you filter the download according to "String KEY_ID = "id";" in an XML? Below is the sample of my XML code. Example, I want to list out the item "String KEY_ID = "id";" from 1 - 20 to show in my gridview. My objective is to limit the xmlparsing. Currently my codes just downloads everything in my xml and shows them in gridview.
myXML.xml
<song>
<id>1</id>
<title>1</title>
<artist>Blabla</artist>
<duration>0</duration>
<thumb_url>https://jpg</thumb_url>
<big_url>https://jpg</big_url>
</song>
<song>
<id>2</id>
<title>2</title>
<artist>Nature</artist>
<duration>0</duration>
<thumb_url>https://jpg</thumb_url>
<big_url>https://jpg</big_url>

XML parsing is actually usually pretty fast (faster than JSON in some phones). But to display just some of the document you might want to look into XPath (java.xml.xpath) - e.g.:
/music/song[id <= 20]
See http://developer.android.com/reference/javax/xml/xpath/package-summary.html
Hi i wrote one xml parsing example.here i have to get the data information from mysql database and display it in android emulator successfully.
this is my code:
public class CustomizedListView extends Activity {
// All static variables
static final String URL = "http://192.168.1.168/xcart432pro/orderdetails.xml";
// XML node keys
static final String KEY_SONG = "Order"; // parent node
static final String KEY_ID = "orderid";
static final String KEY_TITLE = "orderid";
static final String KEY_ARTIST = "payment_method";
static final String KEY_DURATION = "total";
ListView list;
LazyAdapter adapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(URL); // getting XML from URL
Document doc = parser.getDomElement(xml); // getting DOM element
NodeList nl = doc.getElementsByTagName(KEY_SONG);
// looping through all song nodes <song>
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_ID, parser.getValue(e, KEY_ID));
map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE));
map.put(KEY_ARTIST, parser.getValue(e, KEY_ARTIST));
map.put(KEY_DURATION, parser.getValue(e, KEY_DURATION));
// adding HashList to ArrayList
songsList.add(map);
}
list=(ListView)findViewById(R.id.list);
// Getting adapter by passing xml data ArrayList
adapter=new LazyAdapter(this, songsList);
list.setAdapter(adapter);
// Click event for single list row
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String Orderid= ((TextView) view.findViewById(R.id.title)).getText().toString();
String Price = ((TextView) view.findViewById(R.id.duration)).getText().toString();
String Description = ((TextView) view.findViewById(R.id.artist)).getText().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra(KEY_TITLE, Orderid);
in.putExtra(KEY_DURATION, Price);
in.putExtra(KEY_ARTIST, Description);
startActivity(in);
}
});
}
}
dis is my singlemenuitem.java class is:
public class SingleMenuItemActivity extends Activity {
// XML node keys
static final String KEY_TITLE = "orderid";
static final String KEY_ARTIST = "payment_method";
static final String KEY_DURATION = "total";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.single_list_item);
// getting intent data
Intent in = getIntent();
// Get XML values from previous intent
String product = in.getStringExtra(KEY_DURATION);
String login = in.getStringExtra(KEY_TITLE);
String description = in.getStringExtra(KEY_ARTIST);
// Displaying all values on the screen
TextView lblName = (TextView) findViewById(R.id.name_label);
TextView lblPName = (TextView) findViewById(R.id.cost_label);
TextView lblDesc = (TextView) findViewById(R.id.description_label);
lblName.setText(login);
lblPName.setText(product);
lblDesc.setText(description);
}
}
Here i have to successfully displayed on android emulator.
but i wish to display on first page orderid and payment_method only.then it is move to next page means have to display total for that particular id.please give me solutions.how can i to do.i wish to my output is :
if i clicked 13 means that particular order total only displayed on next activity.
How is to do.please help me.
i got the answer.if u need hide the "description" field by adding andorid:visibility="gone" to description label in your xml file. So that the description filed will be present in listview but it won't be visible.
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra("KEY_TITLE", Orderid);
in.putExtra("KEY_DURATION", Price);
in.putExtra("KEY_ARTIST", Description);
startActivity(in);

product = getIntent().getExtras().getString("KEY_TITLE");
login = getIntent().getExtras().getString("KEY_DURATION");
description = getIntent().getExtras().getInt("KEY_ARTIST");

i think i need to parse through the imageloader class maybe
You can simply try this one -
URL url = new URL("http://image10.bizrate-images.com/resize?sq=60&uid=2216744464");
Bitmap bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
imageView.setImageBitmap(bmp);
Create one ImageView in your CustomizedListView class and oncreate() method receive url path from the calling file through intent. And paste it in below code and try it.
And, have a look this example
