I have problem with calling startActivity(intent) from onItemClickListener() on ListFragment. When I click on an item from listview the application crashes.

I made one ListView with image and text. I am able to parse json data in the ListView. But my requirenment is to load 10 rows of Json data, then at the bottom have a load more. to get the next 10, etc etc.
Suggest me if anyone knows the solution using json please...
Here is my code for Adapter.java
public class LazyAdapter extends BaseAdapter {
private Activity activity;
private ArrayList<HashMap<String, String>> data;
private static LayoutInflater inflater=null;
public ImageLoader imageLoader;
public LazyAdapter(Activity a, ArrayList<HashMap<String, String>> d) {
activity = a;
data=d;
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
imageLoader=new ImageLoader(activity.getApplicationContext());
}
public int getCount() {
return data.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi=convertView;
if(convertView==null)
vi = inflater.inflate(R.layout.list_row, null);
TextView title = (TextView)vi.findViewById(R.id.title); // title
TextView artist = (TextView)vi.findViewById(R.id.artist); // artist name
TextView duration = (TextView)vi.findViewById(R.id.duration); // duration
ImageView thumb_image=(ImageView)vi.findViewById(R.id.list_image);
ImageView thumb_image1=(ImageView)vi.findViewById(R.id.imageView1);// thumb image
HashMap<String, String> song = new HashMap<String, String>();
song = data.get(position);
// Setting all values in listview
title.setText(song.get(CustomizedListView.USER_NAME));
artist.setText(song.get(CustomizedListView.KEY_ARTIST));
duration.setText(song.get(CustomizedListView.KEY_DURATION));
imageLoader.DisplayImage(song.get(CustomizedListView.KEY_THUMB_URL), thumb_image);
imageLoader.DisplayImage(song.get(CustomizedListView.KEY_THUMB_URL1), thumb_image1);

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);
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:

// 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++) {

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() {

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

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

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.
My list view is parsed from a online resource, but i cant get the listview to pass the image src to the single list item

// Starting new intent
Intent in = new Intent(CustomizedListView.this, org.scouts.library.SingleMenuItem.class);
in.putExtra(KEY_SONG, song);
in.putExtra(KEY_ARTIST, artist);
in.putExtra(KEY_THUMB_URL, thumb_url);
in.putExtra(KEY_DURATION, duration);
startActivity(in);
}
});
}
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
