How to use setTag and getTag with custom adapter

Question

I get stucked and I need help. I'm trying to use set and get Tag but i can't get how it works for this action:

• I'm using list view to show images loaded to extended adapter
• The custom Adapter inflate a layout with imageview_1, textview_1 and button_1
• On my principal activity, I have a "Public Void OnClickHandler" for button_1 and was configurated on layout with "android:onClick", so when button is clicked it do something
• When button_1 is clicked, I want to get the text from textview_1 from that specific view and then load a different image. I want to to this using get and set TAGS, so I need to do the reference with button_1 and imageview_1. here my snipped code. Thank you in advance

The custom Adapter

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder = null;

    LayoutInflater mInflater = (LayoutInflater) 
        context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);

    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.itemstartsession, null);
        holder = new ViewHolder();

        holder.image = (WebView)convertView.findViewById(R.id.img_session);
        //holder.image.setTag(position);

        holder.code = (TextView)convertView.findViewById(R.id.code_item_session_text);
        //holder.code.setTag(position);


        holder.share=(ImageButton)convertView.findViewById(R.id.share_item_session_button);
        holder.share.setTag(position);

        convertView.setTag(holder);
    // Check if my setTag is ok for button and get the reference to get 
        //text from textview and the referece to webview, then I gonna load a url
    } else {

        holder=(ViewHolder)convertView.getTag();
    }

    StoreDataForBA storeItem= (StoreDataForBA) getItem(position);
    holder.image.loadUrl(storeItem.getImage());

        holder.code.setText(storeItem.getCode());

return convertView;
}

This is my getter and setter for data, very easy

public StoreDataForBA( String image, String code) {

    this.setImage(image);
    this.setCode(code);

}

public String getImage() {
    return image;
}

public void setImage(String image) {
    this.image = image;
}


public String getCode() {
    return code;
}

public void setCode(String code) {
    this.code = code;
}

My principal Activity snipped

public void shareOnClickHandler(View v) {
// plz here i need the code to get the text from textview and also get the 
// reference of the webview, so i can do something like
// StoreDataForBA data = (StoreDataForBA)v.getTag();
// image2.loadUrl("http://image2")..... I'm not sure, thank you
