Create CardView with dynamic custom list inside

问题

I create a RecyclerView with CardViews in my app. Now I want to add inside each CardView a new List of custom Views, with a custom layout (see example Image). When the add button is pressed, there should be insert a new row of this layout inside the card.

How do I realize that? In the internet I readed, that a ListView inside the CardView is not possible, because a ListView is scrollable, and there should not be two scrollable Views on the activity (thats what I found..)

the red marked row is the custom row.

for the RecylcerView I used the ViewHolder, CustomAdapter, etc. Do I need this for the rows inside to? or is there a simpler way?

回答1:

What I would do is attached a click handler to the Views is your ViewHolder. In this event handler you can delegate to a presenter of some sort that will add/remove/edit the View in the card holder.

 private class MyHolder extends ViewHolder 
        implements View.OnClickListener {
    ...

    public MyHolder(View itemView, MyPresenter presenter) {
        super(itemView);
        itemView.setOnClickListener(this);

        ...
    }

    @Override
    public void onClick(View v) {
        presenter.addRow(v);
    }
}
