Getting Listview Row Data

I have a listview in my application.I want to set the value of textview in that particular row when I click one of the textview in that row itself.so,I tried like below likes.setOn

Solution 1:

I'm not sure how you are populating your list with data, however here is a method I use that works very well.

Data Models

publicclassPublication {

publicString string1;
publicString string2;

publicPublication()  {

}
publicPublication(String string1, String string2) {
this.string1= string1;
this.string2= string2;
}


}

Create an array adapter

publicclassContactArrayAdapterextendsArrayAdapter<ContactModel> {
privatestaticfinalStringtag="ContactArrayAdapter";
privatestaticfinalStringASSETS_DIR="images/";
private Context context;
    //private ImageView _emotionIcon;private TextView _name;
private TextView _email;
private CheckBox _checkBox;

private List<ContactModel> contactModelList = newArrayList<ContactModel>();
publicContactArrayAdapter(Context context, int textViewResourceId,
                           List<ContactModel> objects) {
    super(context, textViewResourceId, objects);
    this.context = context;
    this.contactModelList = objects;
}

publicintgetCount() {
    returnthis.contactModelList.size();
}
public ContactModel getItem(int index) {
    returnthis.contactModelList.get(index);
}
public View getView(int position, View convertView, ViewGroup parent) {
    Viewrow= convertView;
    if (row == null) {
        // ROW INFLATION
        Log.d(tag, "Starting XML Row Inflation ... ");
        LayoutInflaterinflater= (LayoutInflater) this.getContext()
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = inflater.inflate(R.layout.contact_list_entry, parent, false);
        Log.d(tag, "Successfully completed XML Row Inflation!");
    }

    // Get itemfinalContactModelcontactModel= getItem(position);
    Resourcesres=this.getContext().getResources();
        //Here are some samples so I don't forget...////_titleCount = (TextView) row.findViewById(R.id.category_count);//  _category.setText(categories1.Category);////if (categories1.Category.equals("Angry")) {//Drawable angry = res.getDrawable(R.drawable.angry);//_emotionIcon.setImageDrawable(angry);//}
    _checkBox = (CheckBox) row.findViewById(R.id.contact_chk);
    _email = (TextView) row.findViewById(R.id.contact_Email);
    _name = (TextView)row.findViewById(R.id.contact_Name);

     //Set the values
    _checkBox.setChecked(contactModel.IsChecked);
    _email.setText(contactModel.Email);
    _name.setText(contactModel.Name);

    _checkBox.setOnClickListener(newCompoundButton.OnClickListener() {
        @OverridepublicvoidonClick(View view) {
            if (contactModel.IsChecked) {
               contactModel.IsChecked = false;
               notifyDataSetChanged();
            }
            else {
                contactModel.IsChecked = true;
                notifyDataSetChanged();
            }

        }
    });

    return row;
}

}

Use the array adapter to fill your list

   ContactArrayAdapter contactArrayAdapter;
   //
   List<ContactModel> contactModelList;
   //Fill list with your method
   contactModelList = getAllPhoneContacts();
   //
   contactArrayAdapter = newContactArrayAdapter(getApplicationContext(),          R.layout.contact_list_entry, contactModelList);
   //setListAdapter(contactArrayAdapter);

A sample method to fill data:

public List<ContactModel> getAllPhoneContacts() {
    Log.d("START","Getting all Contacts");
    List<ContactModel> arrContacts = newStack<ContactModel>();

    Uriuri= ContactsContract.CommonDataKinds.Email.CONTENT_URI;
    Cursorcursor= getContentResolver().query(uri, newString[] {ContactsContract.CommonDataKinds.Email.DATA1
            ,ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME
            ,ContactsContract.CommonDataKinds.Phone._ID}, null , null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
    cursor.moveToFirst();
    while (cursor.isAfterLast() == false)
    {
        String email= cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
        Stringname=  cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        intphoneContactID= cursor.getInt(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID));




        if (email != null)
        {
            ContactModelcontactModel=newContactModel();
            contactModel.Name = name;
            contactModel.Email = email;
            contactModel.IsChecked = false;
            arrContacts.add(contactModel);
        }

        cursor.moveToNext();
    }
    cursor.close();
    cursor = null;
    Log.d("END","Got all Contacts");
    return arrContacts;
}

Accessing the data on click

finalListViewlv= getListView();
        lv.setTextFilterEnabled(true);
        //Click handler for listview
    lv.setOnItemClickListener(newOnItemClickListener() {
       publicvoidonItemClick(AdapterView parent, View view, int position, long id) {
            ContactModel contact= getItem(position);//This gets the data you want to change//
            some method here tochange set data
            contact.email = "new@email.com"//send notification
             contactArrayAdapter.notifyDataSetChanged();
        }
    });
