Target Must Not Be Null Using Picasso Library

I implemented a listView using the Picasso Library 2.4.0 and I'm facing an issue. What happens: I launch the app using Android Studio, then I go to the specific fragment on which I

Solution 1:

The error occurs because holder.image is null - and into() specifically checks that the argument you pass in is not null.

When you use setTag()/getTag(), only a single object can be stored. Therefore when you call

view.setTag(holder);
view.setTag(holder1);

None of the data in holder is saved - it is replaced with holder1. Instead of having multiple ViewHolder, you should just add another field to your existing ViewHolder class:

classViewHolder {
  ImageView image;
  TextView url;
  TextView price;
}

Then you can use just a single ViewHolder:

holder = new ViewHolder();

holder.image = (ImageView) view.findViewById(R.id.photo);
holder.url = (TextView) view.findViewById(R.id.url);
holder.price = (TextView) view.findViewById(R.id.price);

view.setTag(holder);
