I have a listfragment which display name of objects stored in a sqlitedatabase and each object has a mac adress and a password which is also stored in the same database how can i do to display the mac adress and the password of the item who is clicked and not all the password or the mac adresses .

Here is the List Fragment with OnListItemClick

 public class F1_fr extends ListFragment {
   View rootview;
    TextView textView1;
    ArrayAdapter<String> aa;
    ArrayList<String> arrayList = new ArrayList<String>();
    SQLiteDatabase db;
    ListView listView;

    @Override
    public void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        Cursor c2 = db.rawQuery("SELECT * FROM test2", null);

        while(c2.moveToNext())
        {

        Toast.makeText(getActivity(), c2.getString(0), Toast.LENGTH_LONG).show();
        Toast.makeText(getActivity(), c2.getString(1), Toast.LENGTH_LONG).show();

        }
    }

    @Override

    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        rootview=inflater.inflate(R.layout.f1_lay,container,false);
        textView1=(TextView)rootview.findViewById(R.id.textView1);
        db = getActivity().openOrCreateDatabase("testDB2", Context.MODE_PRIVATE, null);
        db.execSQL("CREATE TABLE IF NOT EXISTS test2(mac VARCHAR,mdp VARCHAR,obj VARCHAR);");

        aa = new ArrayAdapter<String>(getActivity(),
                android.R.layout.simple_list_item_1,  arrayList);
        setListAdapter(aa);



                    Cursor cursor = db.rawQuery("SELECT * FROM test2", null);
                    //  Toast.makeText(myContext, ""+cursor.getCount(), Toast.LENGTH_LONG).show();
                    if(cursor.moveToFirst())

                    {
                        do {
                            arrayList.add(cursor.getString(2));


                        } while (cursor.moveToNext());
                    }


                   rootview.findViewById(R.id.semi_transparent).

                    setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick (View v){

                            Intent intent = new Intent(getActivity(), ajout.class);
                            startActivityForResult(intent, 2);

                        }

                    }

                    );
                    return rootview;

                }
