    View itemView;


    if (convertView == null) {
        itemView = layoutInflater.inflate(R.layout.activity_delivering_partner_item, parent, false);

The specified child already has a parent. You must call removeView() on the child's parent first

Due to :

partner_linear.addView(addView);

line.

Inside for-loop adding same object of View multiple times in partner_linear.

To get it work inflate activity_delivering_partner_item_row layout in for-loop :

for(int k = 0; k< deliveringListActivity.partner_goods_arr.size(); k++){
  // inflate layout and access all Views from it here
   final View addView = layoutInflater.inflate(
                      R.layout.activity_delivering_partner_item_row, null);
   TextView goods_name = (TextView) 
                      addView.findViewById(R.id.partner_goods_name_row);

 .... your code here...

    partner_linear.addView(addView);
}

First important thing to know when you are adding a child view in Android is "A child can have only 1 parent" here the textView which you are adding is already a child for a layout in xml file so you cannot set another parent for that child.Instead of using FindViewById() try to add TextViews dynamically by creating objects for TextView class and set parameters for those textViews using LayoutParams.

You are adding same view again and again to parent_linear. You need to create a new view everytime you iteratate in forloop

 for(int k = 0; k< deliveringListActivity.partner_goods_arr.size(); k++){
  // inflate layout and access all Views from it here
   final View addView = layoutInflater.inflate(
                      R.layout.activity_delivering_partner_item_row, null);
   TextView goods_name = (TextView) 
                      addView.findViewById(R.id.partner_goods_name_row);

 .... your code here...

    partner_linear.addView(addView);
}
