I am trying to display a context menu on clicking item in a recycler view, and the choose to call the person whose name has been clicked. But I am unable to retrieve the phone number because the getMenuInfo() is not working bcoz I am getting a null in contextMenuInfo in onCreateContextMenu(). I have referenced many answers and written my code accordingly but still not able to correct it Here is my code:
menu_actions.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/call"
android:title="Call">
</item>
<item
android:id="@+id/sms"
android:title="Send SMS">
</item>
<item
android:id="@+id/email"
android:title="Send email">
</item>
<item
android:id="@+id/viewContact"
android:title="View Details">
</item>
<item
android:id="@+id/editContact"
android:title="Edit Contact">
</item>
<item
android:id="@+id/deleteContact"
android:title="Delete">
</item>
</menu>
My fragment which contains the recycler view:
public class MyContacts extends Fragment {
public static RecyclerView recyclerView;
public static Person receivedData;
static Context c;
static int itemIndex;
DatabaseAdapter dbAdapter = new DatabaseAdapter(getContext());
private static RecyclerViewAdapter recyclerViewAdapter;
ArrayList<Person> persons = new ArrayList<>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
c = getContext();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
MainActivity activity = (MainActivity) getActivity();
receivedData = activity.getData();
View layout = inflater.inflate(R.layout.fragment_my_contacts, container, false);
recyclerView = (RecyclerView) layout.findViewById(R.id.myContactsList);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity());
recyclerView.setLayoutManager(layoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerViewAdapter=new RecyclerViewAdapter(activity, persons);
recyclerView.setAdapter(recyclerViewAdapter);
registerForContextMenu(recyclerView);
retrieve();
return layout;
}
public void retrieve()
{
persons.clear();
DatabaseAdapter databaseAdapter = new DatabaseAdapter(c);
databaseAdapter.openDB();
//retrieves the whole table from DB
Cursor cursor = databaseAdapter.getDataForList();
// loop and add to array list
while (cursor.moveToNext())
{
int index1 = cursor.getColumnIndex(Constants.PHONE);
String name = cursor.getString(index1);
......
Person p = new Person(name, phone, address, email, dob, R.id.contactImage);
persons.add(p);
}
//if array list not empty
if (!(persons.size() <1))
{
recyclerViewAdapter.notifyDataSetChanged();
}
databaseAdapter.closeDB();
}
@Override
public void onCreateContextMenu(ContextMenu menu, View view, ContextMenu.ContextMenuInfo menuInfo) // here menuInfo is coming NULL
{
super.onCreateContextMenu(menu, view, menuInfo);

//Initializing view holder

Person current = persons.get(position);
holder.image.setImageResource(R.drawable.contact);
holder.name.setText(current.getName());

}
@Override

TextView phone;
ItemClickListener itemClickListener;
ContextMenuRecyclerView recyclerView = new ContextMenuRecyclerView(c);
public MyViewHolder(View itemView) {
super(itemView);
