My recycler view adapter is as follows
@Override
public ContactViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View itemView = LayoutInflater.from(viewGroup.getContext()).
inflate(R.layout.contacts_list_item, viewGroup, false);
return new ContactViewHolder(itemView);
}
@Override
public void onBindViewHolder(ContactViewHolder viewHolder, int position) {
super.onBindViewHolder(viewHolder, position);
viewHolder.removeContact.setTag(position);
Contact contact = contacts.get(position);
viewHolder.contactName.setText(contact.getContactName());
viewHolder.contactNumber.setText(contact.getContactNumber());
viewHolder.removeContact.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Integer taggedPosition = (Integer) v.getTag();
Log.wtf("ad","Posirtion"+ Integer.toString(taggedPosition));
contacts.remove(Integer.parseInt(Integer.toString(taggedPosition)));
notifyItemRemoved(Integer.parseInt(Integer.toString(taggedPosition)));
}
});
}
@Override
public int getItemCount() {
return contacts.size();
}
public void removeItem(int pos) {
contacts.remove(pos);
// notifyItemRemoved(pos);
}
public void add(Contact contact, int position) {
contacts.add(position, contact);
notifyItemInserted(position);
}
and my view holder is
class ContactViewHolder extends RecyclerView.ViewHolder {
public TextView contactName,contactNumber;
public ImageButton removeContact;
public ContactViewHolder(View itemView) {
super(itemView);
contactName= (TextView) itemView.findViewById(R.id.tv_contactName);
contactNumber= (TextView) itemView.findViewById(R.id.tv_contactNumber);
removeContact= (ImageButton) itemView.findViewById(R.id.ib_removeItem);
}
}
The issue is i cant seem to get the postion of viewHolder.removeContact
.All i want to achieve is to remove the row when the viewHolder.removeContact
is clicked.I have tried getting the postion by getTag() method also but it gives me only one postion ie 0.

Thanks to @pskink.Thanks. Solved the issue all i did was to pass the reference of my adapter and contacts
arraylist to my view holder class like this
@Override
public ContactViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View itemView = LayoutInflater.from(viewGroup.getContext()).
inflate(R.layout.contacts_list_item, viewGroup, false);
return new ContactViewHolder(itemView,this,contacts);
}
where itemView
is the View to be returned,this
is the adapter refrence and contacts
is the arraylist i have to updated on button click.My ViewHolder class loooks like this
class ContactViewHolder extends RecyclerView.ViewHolder {
public TextView contactName,contactNumber;
public ImageButton removeContact;
private List<Contact> contacts1;
private ContactsAdapter contactsAdapter1;
public ContactViewHolder(View itemView, ContactsAdapter contactsAdapter, final List<Contact> contacts) {
super(itemView);
this.contacts1=contacts;
this.contactsAdapter1=contactsAdapter;
contactName= (TextView) itemView.findViewById(R.id.tv_contactName);
contactNumber= (TextView) itemView.findViewById(R.id.tv_contactNumber);
removeContact= (ImageButton) itemView.findViewById(R.id.ib_removeItem);
removeContact.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
contacts1.remove(getPosition());
contactsAdapter1.notifyItemRemoved(getPosition());
}
});
}
}
