ContextMenuRecyclerView - simple sample on how to adapt an existing ContextMenu to RecyclerView

MyListFragment.java

    ContextMenuRecyclerView extends Recycler View {

    onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
     //... 
     registerForContextMenu(mList);
    }

    //////////////////////////////////////////////////////////////////
    //// Menu
    //////////////////////////////////////////////////////////////////
    @Override
     public void onContextualMenuClicked(Track track, View view) {
         //call this callback from your viewholder.
         getActivity().openContextMenu(view);
     }
    
    
    @Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
        super.onCreateContextMenu(menu, v, menuInfo);
        
       
        dz.ui.Menu.MenuItem[] currentContextMenuItems = getCurrentContextMenuItems(
                menu, v, menuInfo);

        if (currentContextMenuItems != null) {

            View header = View.inflate(getActivity(),
                    R.layout.context_menu_header, null);
           
            menu.setHeaderView(header);

            // configure the header and add your menuItems
        }
    }

    @Override
    public boolean onContextItemSelected(MenuItem item) {
        // Never call super.onOptionsItemSelected(item), otherwise there will be a infinite loop
        ABaseActivity activity = (ABaseActivity) getActivity();
        return activity.onMenuEvent(activity,
                dz.ui.Menu.getSavedMenuItem(item.getItemId()));
    }



    public void customizeContextMenuHeaderView(ContextMenu.ContextMenuInfo menuInfo, RemoteImageView picture,
                                               TextView mainText, TextView secondText, TextView thirdTextView) {

    }

        if (mAdapter == null) {
            return null;
        }
        RecyclerContextMenuInfo info =
                (ContextMenuRecyclerView.RecyclerContextMenuInfo) menuInfo;
        int position = info.position;

        ///// do whatever you need to get your MenuItem Array and return it.

        

        return null;
    }
}

I wrote this for the RecyclerView preview code, there might be an easier/cleaner way to do this now.

hello! could suggest how I could do:

ContextMenuRecyclerView view = (ContextMenuRecyclerView) activity.findViewById(id);

would have to turn ContextMenuRecyclerView in a Adapter?

I'm try

    <ContextMenuRecyclerView
        android:id="@+id/repertorios_list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

but...

```JAVA
android.view.InflateException: Binary XML file line #48: Error inflating class ContextMenuRecyclerView

Use fully qualified name instead of just ContextMenuRecyclerView.

Hey, I needed to get the targetView of the ContextMenuInfo, and it works if you just add support for a View targetView in RecyclerContextMenuInfo

public static class RecyclerContextMenuInfo implements ContextMenu.ContextMenuInfo {

    public RecyclerContextMenuInfo(int position, long id, View targetView) {
        this.position = position;
        this.id = id;
        this.targetView = targetView;
    }

    public int position;
    public long id;
    public View targetView;
}

So you can access the context menu title. 👍

(For anyone who may need it...)
