android.view.InflateException: Binary XML file line #19: Error inflating class fragment

Question

EDIT: This is not a duplicate, I have fixed the NullPointerException and its no longer duplicate. Please unflag this as duplicate.

Thanks to @Fondesa, I had already fixed the NullPointerException. I have read the other Question @Tunaki linked it to, it was helpful. But it didn't solve my problem completely.

I'm trying to have a listfragment in my main activity, but there's the android.view.InflateException. Any help would be very deeply appreciated. I've been stuck at this for a day now.

This is the error log.

            android:layout_alignParentStart="true" />
    </android.support.v4.widget.SwipeRefreshLayout>
    <android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/drawer_view"/>
</android.support.v4.widget.DrawerLayout>

The fragment class that is failing.

public class ADlister extends ListFragment implements SwipeRefreshLayout.OnRefreshListener, AdapterView.OnItemClickListener {
private fragCTA.OnFragmentInteractionListener mListener;
ListView listView;
ArrayList <Result> results;
FragmentListAdapter adapter;

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

// TODO: Rename and change types and number of parameters


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

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

    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.fragment_adlister, container, false);
    listView =(ListView)view.findViewById(R.id.prodlistview_fragement);
    Exxplore exxplore= (Exxplore) getActivity();
    results=exxplore.getlist();
    if(results!=null&&results.size()!=0)
        lister();
    return view;
}
void lister(){
    int count=results.size();
    String produrls[]=new String[count];
    String prodname[]=new String[count];
    for(int i=0;i<count;i++){
        prodname[i]=results.get(i).getProduct_title();
        produrls[i]=results.get(i).getProduct_url();
    }
    this.setListAdapter(adapter);
    assert listView != null;
    listView.setAdapter(adapter);
    listView.setOnItemClickListener(this);
}
@Override
public void onRefresh() {
    Exxplore exxplore= (Exxplore) getActivity();
    results=exxplore.getlist();

    lister();
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

}

The function exxplore.getlist() returns an array list of type Result.

Did you tried changing "android:name" in fragment tag to "class" ? — Sunil Sunny, Jun 07 '16 at 07:04

First you need to solve this error at com.idiots.redundant.digiteyes_beacon.ADlister.lister(ADlister.java:64)

Caused by: java.lang.ArrayIndexOutOfBoundsException: length=0; index=0
at com.idiots.redundant.digiteyes_beacon.ADlister.lister(ADlister.java:64)

Fixed that. Still the same error. I have made some edits in the question could you please check again? – Prashanth Ambati Jun 07 '16 at 07:10
I could not found where you initialize your adapter. check if it is null or what. and also check at here. **com.idiots.redundant.digiteyes_beacon.ADlister.onCreateView(ADlister.java:50)** – Sagar Thakarar Jun 07 '16 at 07:23

EDIT

After your edit, you have to check for null list in onCreateView():

if(results != null && results.size()!=0)
    lister();

You should add in a null check for results -

results = exxplore.getlist();
if (results != null && results.size() != 0)
    lister();
return view;

 Exxplore exxplore= (Exxplore) getActivity();

Its not ideal way to get Activity Instance inside your onCreateView() method. Please use onAttach(Activity mActivity) method to get your activity Instance.

onAttach(android.app.Activity) deprecated it says – Prashanth Ambati Jun 07 '16 at 07:18

Yeah did that. Thank You. Although the isn't the exact issue. – Prashanth Ambati Jun 07 '16 at 09:13
