I'm developing an Android application for read some information from a XML file on the web. At first, I had a problem to parsing. Now my problem is that my code read only one information. I've created my class MyFilm. How can I insert all information from that file in my arraylist. Thank you in advance.
public class FilmListActivity extends ListActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new WebService() {
#Override
protected ArrayList<MyFilm> doInBackground(Object... params) {
ArrayList<MyFilm> arr = new ArrayList<MyFilm>();
Intent intent = getIntent();
String pkg = getPackageName();
try {
MyFilm parametriRicerca = new MyFilm();
parametriRicerca = (MyFilm) intent.getSerializableExtra(pkg+".MyFilm");
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser xpp = factory.newPullParser();
URL input = new URL("http://whatdowedo.altervista.org/griffith_list2.xml");
xpp.setInput(input.openStream(), null);
int eventType = xpp.getEventType();
String currentTag = null;
MyFilm tmp = new MyFilm();
String title = null;
String regista = null;
String attore = null;
String genere = null;
String paese = null;
while (eventType != XmlPullParser.END_DOCUMENT) {
if (eventType == XmlPullParser.START_TAG) {
currentTag = xpp.getName();
} else if (eventType == XmlPullParser.TEXT) {
if ("title".equals(currentTag)) {
title = xpp.getText().trim();
}
if("director".equals(currentTag)){
regista = xpp.getText().trim();
}
if("country".equals(currentTag)){
paese = xpp.getText().trim();
}
if("genre".equals(currentTag)){
genere = xpp.getText().trim();
}
if("cast".equals(currentTag)){
attore = xpp.getText().trim();
}
if(parametriRicerca.getTitle().equals(title)){
arr.add(parametriRicerca);
}
}
eventType = xpp.next();
}
} catch (Exception e) {
e.printStackTrace();
}
return arr;
}
}.execute();

When onCreate(savedInstanceState) is called, check whether savedInstanceState is null, and if not, then getExtras from it (as it's a Bundle).
if (savedInstanceState != null)
savedInstanceState.getParcelable(key)
Then do whatever you'd like with the object.
obj is a string with the Id for a specific object in my parse database. I want to get individual rows values and show them in a text view. The below code is what I've got. Not sure why but the query alwasy seems tho return empty. Thus my strings restName,restCuisine,etc all have their initialized values only i.e their values aren't changing because of my query. Any help would be appreciated
public class SingleRestraunt extends ActionBarActivity {
private GoogleMap map;
TextView resteName, resteCuisine, resteLocation, resteAddress;
String restName = "nothing", obj, restCuisine = "nothing",
restLocation = "nothing", restAddress = "nothing";
Double Lang = 19.144378, Long = 72.837135;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

resteLocation = (TextView) findViewById(R.id.restrauntLocation);
resteAddress = (TextView) findViewById(R.id.restrauntAddress);
Intent i = getIntent();
obj = i.getStringExtra("restId");
getDetails(obj);
}
private void getDetails(final String obj) {
ParseQuery<ParseObject> query = ParseQuery.getQuery("resdb");
query.getInBackground(obj, new GetCallback<ParseObject>() {
#Override
public void done(ParseObject object, ParseException e) {
if (e == null) {
restName = object.getString("name");
restCuisine = object.getString("cuisine");

I think it is not correct to call prepareMap(Lang, Long) and addData() after to the call query.getInBackground(...) because "In background" means in a different Thread. You should reorder your calls like this:
ParseQuery<ParseObject> query = ParseQuery.getQuery("resdb");
query.getInBackground(obj, new GetCallback<ParseObject>() {
#Override
public void done(ParseObject object, ParseException e) {
if (e == null) {
restName = object.getString("name");
restCuisine = object.getString("cuisine");
restLocation = object.getString("location");
restAddress = object.getString("address");
// Update your info after to get the rest info
prepareMap(Lang, Long);
addData();
} else {
e.printStackTrace();
}
}
});
I hope this help you!
I have a simple application that pulls an XML file from pc worlds RSS feed here:
http://feeds.pcworld.com/pcworld/latestnews
I want to display the name of the titles in a ListView then when the user selects one the article opens up in a browser window.
The application is working the only thing is that the title is not being displayed correctly in the ListView.
It should be something like this:
Make you website stand out with Windows 8
But instead it is this:
com.example.simplerss.Item#424b9998
Any ideas?
This is my code for the MainActivity
public class MainActivity extends ListActivity {
ArrayAdapter<Item> adapter;
List<Item>items;//Holds item objects containing info relating to element pulled from XML file.
Item item;
#Override

}
public void onPostExecute(String s) {
Toast.makeText(getApplicationContext(), s + " Items: " + items.size(), Toast.LENGTH_SHORT).show();

}
}
}
and for the Item Class
public class Item {
//Variables
private String title;
private Uri link;
private String description;
public Item() {
super();
}
public String getTitle() {

}
public void setTitle(String title) {

}
public void setLink(Uri link) {
this.link = link;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
Override the toString() method in Item.
#Override
public String toString() {
return title;
}
This should solve your problem.
Right now, the ArrayAdapter sets its View's texts to Item.toString(), but this is the default method of Object that returns the Object's ID. With overriding it, you give it a meaningful value, in your case the title.
I think the problem lies in:
else if (xpp.getName().equalsIgnoreCase("title")) {
if (insideItem){
item.setTitle(xpp.nextText());
Log.i("title", item.getTitle());
}
}
Here, getName() is a method from the Java Class object. The method you want is readContent() I think. I haven't used this library so that may not be exactly correct but you can certainly find what you need in the docs.
i have to parse xml file to get country details like country name and country postal code.
how can i parse country names to spinner adapter and when i select perticular country using spinner i have to display particular country code in textview.

Here is a Interface by which you can get the selected country from the spinner
OnItemSelectedListener OnCountrySelected = new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View v, int position,
long id) {
if(position != AdapterView.INVALID_POSITION) {
System.out.println("Country name = " + arrCountries.get(position).getName());
//Here you can set this value to the textview
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
};
Here is a way how you can set the Listener to the spinner
spCountry.setOnItemSelectedListener(OnCountrySelected);
Here is a code to open file as inputstream from assets
try {
InputStream inputStream = v.getContext().getAssets().open("path of file");
ArrayList<Country> arrCountries = parseCountry(this, inputStream);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
When you get the response in the array of Country then set adapter to the spinner
CountryAdapter countryAdapter = new CountryAdapter(arrCountry);
spCountry.setAdapter(countryAdapter);
