Try this code out:

Sending Activity

 public void registerCallClickBack() {
    ListView list = (ListView) findViewById(R.id.listView1);
    list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View viewClicked,
                int position, long id) {
            TextView tv1 =(TextView)viewClicked.findViewById(R.id.stock_name);
            TextView tv2 =(TextView)viewClicked.findViewById(R.id.stock_price);
            Intent intent = new Intent(MainActivity.this, StockItem.class);


            intent.putExtra("name", tv1.getText().toString());
            intent.putExtra("price",tv2.getText().toString());

            //passes all you stock info (note you do not need the above 2 lines)
            intent.putExtra("stockInfo", stocksList.get(position));
            startActivity(intent);
        }
    });
}

Receiving activity

HashMap<String, String> hashMap = (HashMap<String, String>) getActivity().getIntent().getSerializableExtra("stockInfo");

I think you are going to need a HashMap. You can pull the data you want from the List and get store it in an array. Something like: HashMap<String,String> map = stocksList.get(0); String[] values = new String[map.size()]; Then you can set each item of the array such as values[position] = map.get(KEY value). Alternative is after getting the map ArrayList<String> values = map.values; Then get the array from the arraylist values.toArray();

I updated to code to send a HashMap to your second activity. There you can use the data to set up the listview.
