Find item clicked on multicolumn ListView

I'm making a two column list view according to this tutorial, its working fine but besides the row clicked i also need to find which column was clicked (column 1 or 2), is it possible to achieve this?

Here is my Main Activity:

public class MainActivity extends AppCompatActivity {

    private ArrayList<HashMap<String, String>> list;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        final ListView listView=(ListView)findViewById(R.id.hotelsList);

        populateList();

        ListViewAdapter adapter=new ListViewAdapter(this, list);
        listView.setAdapter(adapter);


        listView.setOnItemClickListener(new AdapterView.OnItemClickListener()
        {
            @Override
            public void onItemClick(AdapterView<?> parent, final View view, int position, long id)
            {
                // TODO find which column was clicked
            }

        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    public void populateList(){
        list=new ArrayList<HashMap<String,String>>();

        HashMap<String,String> temp=new HashMap<String, String>();
        temp.put("Hotel_Name_1", "Hotel 1");
        temp.put("Hotel_Description_1", "Descripcion Hotel 1");
        temp.put("Hotel_Name_2", "Hotel 2");
        temp.put("Hotel_Description_2", "Descripcion Hotel 2");
        list.add(temp);

        HashMap<String,String> temp2=new HashMap<String, String>();
        temp2.put("Hotel_Name_1", "Hotel 3");
        temp2.put("Hotel_Description_1", "Descripcion Hotel 3");
        temp2.put("Hotel_Name_2", "Hotel 4");
        temp2.put("Hotel_Description_2", "Descripcion Hotel 4");
        list.add(temp2);

        HashMap<String,String> temp3=new HashMap<String, String>();
        temp3.put("Hotel_Name_1", "Hotel 5");
        temp3.put("Hotel_Description_1", "Descripcion Hotel 5");

        temp3.put("Hotel_Name_2", "Hotel 6");
        temp3.put("Hotel_Description_2", "Descripcion Hotel 6");
        list.add(temp3);
    }
}

Modify this in your code

  listView.setOnItemClickListener(new AdapterView.OnItemClickListener()
    {
        @Override
        public void onItemClick(AdapterView<?> parent, final View view, int position, long id)
        {
            HashMap<String,String> selectedItem=list.get(position);//you will get the clicked item here you can use further as you want

        }

    });

Yes it it possible to do it from adapter here is an example of mine

in getview method of adapter ,set onClickListner there like below

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    convertView = null;

    ViewHolderCategory holder;
    holder = new ViewHolderCategory();

    if (convertView == null) {

        convertView = mInflater.inflate(R.layout.item_category_list, null);

        holder.tv = (TextView) convertView.findViewById(R.id.textView1);
        holder.tv.setText(mTotalCategoriesItems.get(position)
                .getCategoryTitle());

        convertView.setTag(holder);
    }

 holder.tv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
    //Do Something Here
}
 });

 //Similary keep on click listner for other views inside listView here
    return convertView;
}

Based on the link you provided, it's just customized listview with multiple textview's.

There is no complexity on that. Just set the tag to that textview.

Like, tv0.setTag("0"),tv1.setTag("1),tv2.setTag("2"),tv3.setTag("3"). and initialize onClikListener to all textview.

When the user click's you will get the clicked view. like 

 tv0.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
    TextView tv=(TextView)v;
    String pos=(String)tv.getTag();

    //you can do like below also.
    //String pos=(String)v.getTag();


  }
 });

Use a GridView instead and then you can easily work with gridView.setOnItemClickListener() method. Cheers!
