How to add overflow icon items in a card in Android

问题

Hi I am trying to create a layout like this using support library https://developer.android.com/reference/android/support/v7/widget/CardView.html but i didn't found a way to add overflow icon in a card.

I don't want to use this library https://github.com/gabrielemariotti/cardslib/blob/master/doc/CARDGRID.md. I want to do same using support library that Google introduced recently.

Isn't there is way to achieve using support library or I have to use gabrielemariotti library to add overflow items in a card view.

Update

Guys I have edited question now it is more clear what i want.

First of all you shouldn't use this lib only to achieve an overflow menu inside a card.

Said that,the CardView in support Library is a FrameLayout with any model behind. The best way to achieve it, now is to use the new Toolbar inside the CardView layout.

Also you can add a ImageView inside the CardView layout and do something like this:

PopupMenu popup = new PopupMenu(getContext(), mImageButton);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.your_menu, popup.getMenu());

Finally (but it is not so important) if it isn't enough, the new cardslib (coming soon) will use the CardView in support library.

Here's how to do it correctly in an android.support.v7.widget.CardView. In my example, it's a cardview inside of a RecyclerView, so I set this up in the adapter, inside the onBindViewHolder method:

public class DashboardItemAdapter extends RecyclerView.Adapter<DashboardItemAdapter.ViewHolder> {
    ArrayList<Item> mItems = new ArrayList<>();
    private Context mContext;

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        mContext = parent.getContext();
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_dashboard, parent, false);
        return new ViewHolder(v);
    }

    @Override
    public void onBindViewHolder(ViewHolder vh, int position) {
        final Item item = mItems.get(position);

        ...

        PopupMenu popup = new PopupMenu(mContext, vh.btnMenu);
        popup.inflate(R.menu.dashboard_card_waiting);
        popup.setOnMenuItemClickListener(item -> {
            switch (item.getItemId()) {
                case R.id.action_cancel:
                    cancelItem();
                    return true;
                default:
                    return true;
            }
        });
        vh.btnMenu.setOnClickListener(btn -> popup.show());
    }

    ...
}
