Filtering On A List

I have a list of Countries and I am using it as a search, so if I am searching for a specific country, once its found the country I want, I selected it from the filtered list. The

Solution 1:

Once for all the time: If you are using AdapterView.setOnItemClickListener, the right way to get clicked item is such implementation:

adapterView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Object item = parent.getItemAtPosition(position);
    }
});

parent.getItemAtPosition(position) returns Adapter.getItem(position) from your adapter used in AdapterView (with setAdapter)

so for example:

• if you are using ArrayAdapter<T> you should cast parent.getItemAtPosition(position) to T and use it ...

• for ArrayAdapter<POJO> use:

  POJO item = (POJO)parent.getItemAtPosition(position);

• if you are using CursorAdapter

  • Cursor c = (Cursor)parent.getItemAtPosition(position);

• if you are using SimpleAdapter

  • Map<String, ?> item = ( Map<String, ?>)parent.getItemAtPosition(position);

of course it depends on your Adapter implementation ... so you should remeber that Adapter should return the right object with getItem(position)

As it is stated in the documentation it apply to: ListView, GridView, Spinner, Gallery and other subclasses of AdapterView

So in your case the right way is obviously:

Countries country = (Countries)parent.getItemAtPosition(position);

Solution 2:

do this way

---

add one method in adapter class to get current list

public ArrayList<Countries> GetCurrentListData() {
        return countryArrayList;
    }

---

CountryAdapter dcAdapter = new CountryAdapter("whatever your perameter");
    listview.setAdapter(dcAdapter);
    lstDoctorsList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                        @Override
                        public void onItemClick(AdapterView<?> parent, View view,
                                                int position, long id) {
                            try {
                                Countries countries = dcAdapter
                                     .GetCurrentListData().get(position);
                                // get data from countries model class

                            } catch (Exception e) {

                            }
                        }
                    });
