Step 1:

Just get data from adapter using position in ListView.

For. e.g.

You have ArrayList<String> data;//

then access like,

GoToDisplay.putExtra("position", data.get(arg2)); // as arg2 referees to clicked item position from ListView

Step 2:

Get Clicked TextView from View

TextView clickedTextView = (TextView)arg1.findViewById(// Id of your TextView); // Or get child from view arg1

GoToDisplay.putExtra("position", clickedTextView.getText().toString());

Note: As we don't know your Adapter data, above code is just example for understanding..

@MehdiRahimi - What is `data` in your case, post code of adapter data. Mine code is just example. – user370305 Mar 03 '15 at 21:43
@MehdiRahimi - In your case it should be, `GoToDisplay.putExtra("position", data.get(arg2).get("name"));` – user370305 Mar 03 '15 at 21:55
