Set onitemclicklistener to search activity search results displayed in a listview

Question

My app' s mainactivity consists of a listview that is retrived from parse.com(i know that parse is getting closed and i am also in the process of migrating).onitemclick shows information about the clicked item in singleitemview activity. This works good

I have a search activity that searches user input from list in main activity and display the search results in listview

I want to add onitemclicklistener to the search results so that it would open and show information corresponding to the search ressult clicked in singleitemview activity as it does in main activity

Now my problem is, I'll try to explain with example

let my main activity list be

America 1
America 2
America 3
Germany 1
Germany 2
Germany 3
France 1
France 2
France 3
Italy 1

now the user searches for Germany in edittext of search activity

The search results displayed are

Germanny 1
Germany 2
Germany 3

If I click germany 1 item from search results it showing information about America 1 from main activity, ,in singleitemview activity

If I click germany 2 item from search results it showing information about America 2 from main activity in singleitemview activity and so on...

What shall i do to show correct information for search results

the search activity code

public class SearchActivity extends Activity implements OnItemClickListener
{

protected  EditText searchedittext;
ImageButton searchButton;
List<ParseObject> ob;
List<CodeList> codelist = null;
FinalAdapter fnladapter;

@Override

Ok you are using an array adapter right ? ((ArrayAdapter)list.getAdapter()).notifyDataSetChanged(); call this method after your new results are obtained. — Sunil Sunny, Feb 25 '16 at 10:45
@user5894647 Just fetch the data from filtered list. You are using original list. Please see my answer. — Rohit5k2, Feb 25 '16 at 10:54

You are getting position of item from filtered list (list after search), but you are fetching item from the unfiltered list. This is causing the new activity to show wrong data. Get the item from currently loaded list.

Replace

intent.putExtra("intro",
                    (codelist.get(position).getIntroduction()));

with

String value = (String)p1.getItemAtPosition(position);
for(int i = 0; i < codelist.size(); i++)
{
    CodeList itemData = (CodeList)codelist.get(i);
    String temp = itemData.getListHeading();
    if(value.equalsIgnoreCase(temp))
    {
        intent.putExtra("intro", itemData.getIntroduction());
        intent.putExtra("conclusion", itemData.getconclusion());
        break;
    }

    if(i == codelist.size() - 1)
    {
        Log.e("onItemClick", "No item found to display");
        retrun;
    }
}

in onItemClick

I will try iit and let you know,thnx – user5894647 Feb 25 '16 at 10:56
@user5894647: Update my answer. Didn't notice item was a string. – Rohit5k2 Feb 25 '16 at 11:09
bro its showing heading of the listitem clicked instead of showing introduction as it would show if it is clicked from mainactivity – user5894647 Feb 25 '16 at 11:19
Do you have this heading in `codelist` items? If yes then search this item in `codelist` using a loop and fetch the introduction. – Rohit5k2 Feb 25 '16 at 11:22
Is `CodeList` your class? Can you post it? – Rohit5k2 Feb 25 '16 at 11:23
ya its my class. I ll post it – user5894647 Feb 25 '16 at 11:24
Also post `getView` method of `FinalAdapter` – Rohit5k2 Feb 25 '16 at 11:27
Sorry, missed something. Try now. – Rohit5k2 Feb 25 '16 at 11:39
ya doing it , thnx for your concern – user5894647 Feb 25 '16 at 11:41
ya that worked,in case i have to add conclusion also do i have to do the same procedure you told for introduction – user5894647 Feb 25 '16 at 11:47
like if i had to add conclusion along with introduction ,, like this intent.putExtra("conclusion (codelist.get(position).getconclusion())); – user5894647 Feb 25 '16 at 11:53
Updated my answer to add conclusion. – Rohit5k2 Feb 25 '16 at 11:57
and also i have to add intent.putextra("conclusion" , value); – user5894647 Feb 25 '16 at 12:01
No I removed that from my answer. Just the code block I have provided. – Rohit5k2 Feb 25 '16 at 12:02
ya ya ok thank you very much, you were the best and most patient coder i have ever met on stack overflow. You waited till my problem was solved – user5894647 Feb 25 '16 at 12:04

try setting custom adapter to searchedlist. as of now you are setting ArrayAdapter<String> instead of that try settings adapter of ArrayAdapter<ArrayList<CodeList>>

and then in onItemClick you will get CodeList object; then you can use this object to pass to next activity via intent
