How to create context menu for RecyclerView

Question

How do I implement context menu for RecyclerView? Apparently calling registerForContextMenu(recyclerView) doesn\'t work. I\'m calling it from a fra

Answer 1

I have combined my solution with the solution from @Hardik Shah:

In the activity I have:

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    if (v.getId() == R.id.rvQuests) {
        getMenuInflater().inflate(R.menu.list_menu, menu);
    }
}

In the Adapter I have:

private MainActivity context;
private int position;

public int getPosition() {
    return position;
}

public void setPosition(int position) {
    this.position = position;
}

public QuestsAdapter(MainActivity context, List objects) {
    this.context = context;
    this.quests.addAll(objects);
}

public class QuestViewHolder extends RecyclerView.ViewHolder {
    private QuestItemBinding questItemBinding;

    public QuestViewHolder(View v) {
        super(v);
        questItemBinding = DataBindingUtil.bind(v);
        v.setOnCreateContextMenuListener(context);
    }
}

@Override
public void onBindViewHolder(final QuestViewHolder holder, int position) {
    Quest quest = quests.get(position);
    holder.questItemBinding.setQuest(quest);
    holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            setPosition(holder.getAdapterPosition());
            return false;
        }
    });
}

@Override
public void onViewRecycled(QuestViewHolder holder) {
    holder.itemView.setOnLongClickListener(null);
    super.onViewRecycled(holder);
}

In fragment I have:

@Override
public boolean onContextItemSelected(MenuItem item) {
    int position = ((QuestsAdapter) questsList.getAdapter()).getPosition();
    switch (item.getItemId()) {
        case R.id.menu_delete:
            Quest quest = questsAdapter.getItem(position);
            App.getQuestManager().deleteQuest(quest);
            questsAdapter.remove(quest);
            checkEmptyList();
            return true;
        default:
            return super.onContextItemSelected(item);
    }
}
