how to OnClick button in LinerLayout to Retreieve particular's row value?

Question

Following is my code.I use spring JSON restful web service to retrieve list of data and display at ADT.Display mulriple rows of data works fine ^_^.

My question is,how do I retrieve particular item row's value on user click button row?

|  Id   | Description | Button  |
|  2    | iPhone 5    |(Submit) |
|  3    | Samsung Tab |(Submit) |

Lets say user click on "submit" button on 2nd row, so that system would know id is 3.

Hope someone advice

Regards

public class MyMainActivity extends ListActivity{

    @Override
    protected void onCreate(){...}

    @Override
    protected void onStart(){
        super.onStart();
        new HttpRequestTask().execute();

    }

    public void pickActions(View v){

    }

    private class HttpRequestTask extends AsyncTask<Void,Void,ArrayList<ItemDetail>>{
        protected ArrayList<ItemDetail> doInBackground(Void... params){

            final String url = "http://10.0.2.2:8080/restdata";
            RestTemplate restTemplate = new RestTemplate();
            restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
            List<ItemDetail> resultList = Arrays.asList(restTemplate.getForObject(url, ItemDetail[].class));
            ArrayList<ItemDetail> list = new ArrayList<ItemDetail>();
            if(resultList.size()>0){
                for(int i=0;i<resultList.size();i++){
                    ItemDetail itemDetail = resultList.get(i);                  
                    list.add(itemDetail);

                }
            }

            return list;
        }

        @Override
        protected void onPostExecute(ArrayList<ItemDetail> list) {
         m_adapter = new TheArrayAdapter(MyMainActivity .this,list);
        setListAdapter(m_adapter);
        }

    }

}

the adapter

public class TheArrayAdapter extends ArrayAdapter<ItemDetail>{
    private ArrayList<ItemDetail> objects;
    private String currentSku;

    public TheArrayAdapter(Context context,ArrayList<ItemDetail> objects){
         super(context,R.layout.activity_main_list,objects);
         the.objects = objects;
    }

    public View getView(int position,View convertView,ViewGroup parent){
        View v = convertView;

        //....//
        ItemDetail i = objects.get(position);

        if(i!=null){
            TextView itemId= (TextView) v.findViewById(R.id.itemId)
            Button btn = (Button) v.findViewById(R.id.submitButton)

            btn.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        //new ListFruitActivity().pickActions(v);
        //String s = currentsku;
        v.getId();
        System.out.println("selected: "+v.getId());
        }
    });


        }



    }
}

the main activity xml

<LinearLayout
    android:clickable="true"
    ....>

<TextView
    android:id="@+id/itemId"
    ....>
</TextView>

<Button
    android:id="@+id/submitButton"
    android:onClick="pickActions"
    android:clickable="true"
    ..../>



</LinearLayout>

Answer 1

One simple way is to use setTag . You can set the item id on the button using setTag like this

Button btn = (Button) v.findViewById(R.id.submitButton)
btn.setTag(id);
btn.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
    // retrieve the button item id
     int itemId = (Integer)v.getTag();
     // now you have the id, do your other stuff based not the id here
    }
});

Answer 2

You have position parameter in the getview meyhod which will tell you which row you are clicking

public View getView(int position,View convertView,ViewGroup parent){
        View v = convertView;

        //....//
        ItemDetail i = objects.get(position);

        if(i!=null){
            TextView itemId= (TextView) v.findViewById(R.id.itemId)
            Button btn = (Button) v.findViewById(R.id.submitButton)

            btn.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        System.out.println("selected: "+position);
        }
    });


        }
