display informations from database by clicking listview

I want to display differents informations depending on what object is clicked i have a listfragment which display only name of objects like : KEYS,SHOES,USB and they are stored in my data base but each element has other information who are already stored but not shown for example KEYS has also a mac adress which is for example 0.0.0.1 and a password which is 123 .

So i want to display the mac adress and the password which correspond to the object who is clicked so who is in the same line in my database.

    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);

    }

    @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;

                }

and the layout :

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:fab="http://schemas.android.com/apk/res-auto"

    android:layout_width="match_parent"
    android:layout_height="match_parent">



    <ListView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@id/android:list"

        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentBottom="true" />

    <TextView
        android:id="@android:id/empty"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:textSize="30sp"
        android:text="" />


    <com.getbase.floatingactionbutton.AddFloatingActionButton
        android:id="@+id/semi_transparent"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        fab:fab_plusIconColor="@color/primaryColorDark"
        fab:fab_colorNormal="@color/primaryColor"
        fab:fab_colorPressed="@color/AccentColor"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true" />


</RelativeLayout>

I already put the method to click item in the list.

Thanks in advance for your help
