Passing data between activities from listview to another activity

Question

I am trying to pass the data from this main activity to another activity

I am successful in sending data between activities .... Like the data from Edit-text to next activity through putExtra and GetExtra methods and passing as intents

But i am facing challenge in this particular task where it involves sending data from listview to an ordinary activity
data is populated in the list view from JSON so when on click of a row how can i send the data from that row to a new activity

Any Ideas,

ativity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ListView
        android:id="@+id/listViewID"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 

        android:layout_gravity="center">
    </ListView>

</LinearLayout>

MainActivity.java

public class MainActivity extends Activity {

    // url to make request
    private static String url = "http://54.218.73.244:7002/";
    List<Item> yourData = new ArrayList<Item>();

    ProgressDialog progressDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //Instantiating ProgressDialog with onCreate method
        progressDialog=new ProgressDialog(MainActivity.this);
        new ParsingAsync().execute();

    }

    private class ParsingAsync extends AsyncTask<Void, Void, Void>
    {

        @Override
        protected void onPreExecute() {
            // TODO Auto-generated method stub
            super.onPreExecute();
            progressDialog=ProgressDialog.show(MainActivity.this, "", "Please Wait", true, false);


        }

        @Override
        protected Void doInBackground(Void... params) {
            // TODO Auto-generated method stub

            // Creating JSON Parser instance
            JSONObjParser jParser = new JSONObjParser();

            // getting JSON string from URL
            JSONArray json = jParser.getJSONFromUrl(url);

            try {
                for (int i = 0; i < json.length(); i++) {
                    JSONObject c = json.getJSONObject(i);

                    // Storing each json item in variable
                    String NAME=c.getString("restaurantNAME");

                    yourData.add(new Item(NAME));
                }
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            // TODO Auto-generated method stub
            super.onPostExecute(result);
            progressDialog.dismiss();
            ListView yourListView = (ListView) findViewById(R.id.listViewID);
            ListAdapter customAdapter = new ListAdapter(MainActivity.this, R.layout.itemlistrow, yourData);
            yourListView.setAdapter(customAdapter);
            yourListView.setOnItemClickListener(new OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                        int position, long id) {
                    // When clicked, show a toast with the TextView text
                    if(position == 0)
                    {
                        //code specific to first list item    
                        Intent myIntent = new Intent(MainActivity.this,CopperChimneyDesc.class);
                        startActivity(myIntent);
                    }else if(position == 1)
                    {
                        //Intent myIntent = new Intent(MainActivity.this,AroyDesc.class);
                        //startActivity(myIntent);                  
                    }

                }
            });
        }

    }

}

item.java

public class Item{
    private String Name;

    public Item(String name){
        this.Name = name;
    }
    public String getName(){
        return Name;
    }
}

Thanks,

so you trying to pass the restaurent name that you clicked in listview — Peshal, Aug 13 '13 at 02:33
In onItemClick, you can get the clicked item using: Item item = yourData.get(position); Now you can pass this item using intent.putExtra, By the way, how does this Item object look like — Peshal, Aug 13 '13 at 02:39
I have updated how item object looks like in the question ... please have a look at it ..... i tried your solution im getting the error in the putextra line as `The method putExtra(String, boolean) in the type Intent is not applicable for the arguments (String, Item)` — , Aug 13 '13 at 02:57
Ok so you would do String item = yourData.get(position).getName(); Then you can add the string to intent using: intent.putExtra("restaurent", item); — Peshal, Aug 13 '13 at 03:02
Thanks, Hey on the final end of another activity how can i get the extra since im not using basket to send the data ..... i find the textview using `findviewbyid` then ? — , Aug 13 '13 at 03:37
On the other end if its textview you would to textView.setText(getIntent().getExtras().getString("restaurent")); I am gonna right this in answer, and please mark it correct if i solved your problem — Peshal, Aug 13 '13 at 03:46

Then you can add the string to intent using:

intent.putExtra("restaurent", item);

On the other end if its textview you would do

textView.setText(getIntent().getExtras().getString("restaurent"));

You can save the data in sharedPreferences and can access it from other activity. Just an idea :)

But how to get the data(JSON) from the listview and store it in a string ... any ideas ? – Aug 13 '13 at 02:33
if the data is static, like `session_key`, I think the `SharePreference` is way to go. – Ye Lin Aung Aug 13 '13 at 02:35
mJsonString = downloadFileFromInternet(urls[0]); if(mJsonString == null /*|| mJsonString.isEmpty()*/) return false; JSONObject jObject = null; try { jObject = new JSONObject(mJsonString); JSONArray jsonImageArray = jObject.getJSONArray("imageTarget"); – Sushil Aug 13 '13 at 02:37

Since you have the index of the item in the listview the user has clicked you can get the item value from the adapter:

String value = (String)customAdapter.getItem(position);
Intent myIntent = new Intent(MainActivity.this,CopperChimneyDesc.class);
intent.putExtra("restaurant_name", value);
startActivity(myIntent);
