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.
please help me.
Thanks in advance.

Here is a code to parse Xml file where you will have to pass inputstream of your local xml file.
public static ArrayList<Country> parseCountry(Context context, InputStream inputStream) {
String KEY = "";
String VALUE = null;
ArrayList<Country> arrCountires = new ArrayList<Country>();
Country country = null;
ArrayList<State> arrStates = null;
State state= null;
ArrayList<City> arrCities = null;
City city = null;
try {
InputStreamReader inputreader = null;
if(inputStream != null) {
inputreader = new InputStreamReader(inputStream);
}
if(inputreader != null) {
XmlPullParserFactory factory = null;
factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser xpp = null;
xpp = factory.newPullParser();
xpp.setInput(inputreader);
int eventType = 0;
eventType = xpp.getEventType();
eventType = xpp.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
if(eventType == XmlPullParser.START_TAG) {
KEY = xpp.getName();
if(KEY.equalsIgnoreCase(TAGS.COUNTRIES)) {
arrCountires = new ArrayList<Country>();
}else if(KEY.equalsIgnoreCase(TAGS.COUNTRY)) {
country = new Country();
arrStates = new ArrayList<State>();
country.setCountryId(xpp.getAttributeValue(null, TAGS.ID));
}else if(KEY.equalsIgnoreCase(TAGS.STATE)) {
state = new State();
arrCities = new ArrayList<City>();
state.setStateId(xpp.getAttributeValue(null, TAGS.ID));
}else if(KEY.equalsIgnoreCase(TAGS.CITY)) {
city = new City();
city.setCityId(xpp.getAttributeValue(null, TAGS.ID));
}
}else if(eventType == XmlPullParser.END_TAG) {
KEY = xpp.getName();
if(KEY.equalsIgnoreCase(TAGS.COUNTRY)) {
country.setArrStates(arrStates);
arrCountires.add(country);
}else if(KEY.equalsIgnoreCase(TAGS.COUNTRY_NAME)) {
country.setCountryName(VALUE);
}else if(KEY.equalsIgnoreCase(TAGS.STATE_NAME)) {
state.setStateName(VALUE);
}else if(KEY.equalsIgnoreCase(TAGS.STATE)) {
state.setArrCities(arrCities);
arrStates.add(state);
}else if(KEY.equalsIgnoreCase(TAGS.CITY)) {
arrCities.add(city);
}else if(KEY.equalsIgnoreCase(TAGS.CITY_NAME)) {
city.setCityName(VALUE);
}
}else if(eventType == XmlPullParser.TEXT) {
VALUE = xpp.getText();
}
eventType = xpp.next();
}
}
}
catch (Exception e) {
e.printStackTrace();
}finally {
if(inputStream != null) {
try {
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return arrCountires;
}
Here is a Country class with Getter and Setter methods.
public class Country {
String countryId;
String countryName;
ArrayList<State> arrStates;
public ArrayList<State> getArrStates() {
return arrStates;
}
public void setArrStates(ArrayList<State> arrStates) {
this.arrStates = arrStates;
}
public String getCountryId() {
return countryId;
}
public void setCountryId(String countryId) {
this.countryId = countryId;
}
public String getCountryName() {
return countryName;
}
public void setCountryName(String countryName) {
this.countryName = countryName;
}
}
Here is a Adapter class to set country in the spinner.
private class CountryAdapter implements SpinnerAdapter{
ArrayList<Country> data;
public CountryAdapter(ArrayList<Country> data){
this.data = data;
}
#Override
public int getCount() {
return data.size();
}
#Override
public Object getItem(int position) {
return data.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public int getItemViewType(int position) {
return android.R.layout.simple_spinner_dropdown_item;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView v = new TextView(getApplicationContext());
v.setTextColor(Color.BLACK);
v.setText(data.get(position).getName());
v.setTextSize(15);
v.setPadding(10, 10, 10, 10);
v.setSingleLine();
v.setEllipsize(TruncateAt.END);
return v;
}
#Override
public int getViewTypeCount() {
return android.R.layout.simple_spinner_item;
}
#Override
public boolean hasStableIds() {
return false;
}
#Override
public boolean isEmpty() {
return false;
}
#Override
public void registerDataSetObserver(DataSetObserver observer) {
}
#Override
public void unregisterDataSetObserver(DataSetObserver observer) {
}
#Override
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
return this.getView(position, convertView, parent);
}
}
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);

search in listview only refreshes the whole list and does not get the result into list

I am getting the data from server using JSON and when i try to search in the listview it just refreshes the whole list and does not narrate it, but when i debug i can see the result on getfilter is right right and it drugsFiltered = (ArrayList<drugs_json_data>) results.values; does have the filtered data inside it. just the listview.setadaptor is being done inside onPostExecute of the asynctask.
here is my adapter code:
public class drugs_adaptor_listView extends ArrayAdapter<drugs_json_data> implements Filterable {

How to do Filter listview in android?

How to do the Filter concept from Below design? I here by attached two screen designs.
DashBoard Fragment -> Having Listview with Base adapter.
The above ListView code is given Below
DashBoardRefactor
public class DashBoardRefactor extends Fragment {
public static ProgressDialog progress;
public static List<DashListModel> dashRowList1 = new ArrayList<DashListModel>();

Clarification:
How do to Filter while click the Filter Button On DashBoard Fragment. Please Suggest the way. I here by attached My Filter design also.
Dashboard Fragment--> Filter Button-> Filter screen-> the Filtered results should view on DashBoard Fragment.
Once click the apply Button Based on the input from Filter screen it filters the list view the result comes from back end team. I have to display that result on Dashboard Fragment.
Kindly please clarify this Filter concept.

Android ListView doesn't populate

This is simple Android project that I did. I get no warnings or errors while running. But the ListView doesn't get populated. I don't understand what's going wrong.
Since I dont' understand where is the exact problem and copy-pasting all the code won't help, here is my project code repository: https://bitbucket.org/geejo/msk-v2
Any kind of help will be appreciated

I am trying to write a program to select multiple items in the listview i populate. but I am having difficulty of selecting multiple items. Please let me know how to do it. Bellow is how i have populate the Arraylist and i have a custom row with checkbox. i need to get the selected items (name, number) on the button click event. Thank you in advance.

notifyDataSetChanged does not update the listView of custom objects after sorting

I am trying to sort the collection in custom arrayadapter and making a call to update the view . However, the view does not gets updated.
There are two values over which I want to sort (date and amount) and have a custom comparators for them.
I can see that the data itself has changed (i.e if a list item has gone outside of view after sorting and when it gets the view, the data it show is the correct data that should exist after sorting).
The second question is about the filter. The way the filter is implemented right now, it does not update the views either.
Here is code
public class SearchActivity extends BListActivity {
