Custom Listview Adapter Null Object Reference

Not sure what hasn't been initialised here, I'm guessing I have to manually create a new row on the list itself but I have no clue how to even start on that. Here is the code I use

Solution 1:

your convertView is null. You are not assigning your layout view in convertView

try use the row as you are using:

row = inflator.inflate(R.layout.fragment_delivery_collect_item, parent, false);

so do:

if(row!= null) {
    handler.mName = (TextView) row.findViewById(R.id.item_name);
    handler.mSize = (TextView) row.findViewById(R.id.item_size);
    handler.mQty = (TextView) row.findViewById(R.id.item_qty);
    handler.mPrice = (TextView) row.findViewById(R.id.item_price);
