How to populate custom list View under fragment activity (extends Fragment)

I want to Add Simple List View of some items under Fragment activity which is extending Fragment but not ListFragment.

Here is My code :

public class ProductListFragment extends Fragment {

String[] ibizzproducts=
        {
                "Attendance",
                "GPS",
                "CCTV"
                "Website"
                "Application"

        };

ListView listView;


public static ProductListFragment newInstance(int sectionNumber) {
    ProductListFragment fragment = new ProductListFragment();
    Bundle args = new Bundle();
    args.putInt(Constants.ARG_SECTION_NUMBER, sectionNumber);
    fragment.setArguments(args);
    return fragment;
}

public ProductListFragment() {
    // Required empty public constructor
}

     @Override
     public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
}

     @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container,
                     Bundle savedInstanceState) {

     List<HashMap<String,String>> aList = new ArrayList<HashMap<String,String>>();

     for(int i=0;i < ibizzproducts.length;i++){
    HashMap<String, String> hm = new HashMap<String,String>();
    hm.put("txt", "Products Here : " + ibizzproducts[i]);

    aList.add(hm);
   }

   String[] from = { "Products Here" };

int[] to = { R.id.listView1};

View v = inflater.inflate(R.layout.fragment_product_list, container, false);

 // ListView list = (ListView)v.findViewById(R.id.listView1);

  listView = (ListView)v.findViewById(R.id.listView1);

   SimpleAdapter adapter = new SimpleAdapter(getActivity().getBaseContext(), aList, R.layout.fragment_product_list, from, to);

   listView.setAdapter(adapter);
    return v;

If I am using this in onCreateView(), thn its giving me error:

java.lang.IllegalStateException: android.widget.ListView is not a  view that can be bounds by this SimpleAdapter

I just want to add simple ListView , so that if i select Product from the navigation Drawer, it should show me this simple List of product items.

please , help me with this. Thanks

i hope it will help you

public class FragmentShowAll extends Fragment {

ListView listViewMsg;
ArrayList<String> array_list=new ArrayList<>();

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_fragment_all, container, false);

       array_list.add("hello");
       array_list.add("hello");
       array_list.add("hello");
       array_list.add("hello");
       array_list.add("hello");

    listViewMsg = (ListView) v.findViewById(R.id.listViewMsg);
    ArrayAdapter<String> adapter=new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,array_list);
    listViewMsg.setAdapter(adapter);

    listViewMsg.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//on click action
        }
    });//listview on click

    return v;
}

Change your code from listView.setAdapter(adapter); to list.setAdapter(adapter);

Keep your eyes open while copy-paste is being done

Here:

listView.setAdapter(adapter);

listView object is null because getActivity().findViewById is used to access ListView from fragment_product_list layout which is layout of Fragment.

Because list object of ListView is initialized from fragment_product_list which is returned from onCreateView method so used it to setAdapter for ListView:

list.setAdapter(adapter);

It is better:

for(int i = 0; i < ibizzproducts.length; i++) {
    HashMap<String, String> hm = new HashMap<String,String>();
    hm.put("txt", "Products Here : " + ibizzproducts[i]);
    aList.add(hm);
}
