Cardslib的CardView OnCardClickListener的onClick方法不会被调用 [英] Cardslib's CardView OnCardClickListener's onClick method not being called

问题描述

我使用这个库在我的应用程序：卡库：指南并创建了一个卡如图所示的例子。
现在，我需要处理一个click事件，但是实例化下面时，我收到一个错误：新Card.OnCardClickListener ，它说 OnCardClickListener是抽象的：不能被实例化。
在我的活动我有这个code：

I am using this library in my app: Card Library : Guide and created a card as shown in the example. Now I need to handle a click event, but I receive an error when instantiating the following: new Card.OnCardClickListener, which says OnCardClickListener is abstract: cannot be instantiated. In my Activity I have this code:

    Card card = new Card(getBaseContext());//getContext()
    CardHeader header = new CardHeader(getBaseContext());
    card.addCardHeader(header);
    final CardViewNative cardView = (CardViewNative) findViewById(R.id.carddemo);
    cardView.setCard(card);

    cardView.setClickable(true);
    cardView.setOnClickListener(new Card.OnCardClickListener()); //error here

有什么不对？如何设置我的卡可点击，然后点击处理/触摸事件？

What's wrong? How can I set my card as clickable and then handle click/touch events?

修改

如果我用这种方式：

cardView.setOnClickListener(new Card.OnCardClickListener(){//error here
        @Override
        public void onClick(Card card, View view) {
            // This will execute when the the card is clicked
        }
    });

它说无法解析方法setOnClickListener（it.gmariotti.cardslib.library.internal.Card.OnCardClickListener）

EDIT1

你们是对的，我设置了 setOnClickListener 在卡上，而且也没有错误了，
但仍没有执行任何动作点击该卡时。这是新的code：

You guys are right, I set the setOnClickListener on the card itself, and there's no error anymore, but still it doesn't perform any action when the card is clicked. That's the new code:

     //Create a Card
    Card card = new Card(this);//getContext()

    //Create a CardHeader
    CardHeader header = new CardHeader(this);
    //....
    //Add Header to card
    card.addCardHeader(header);

    //Set card in the cardView
    CardViewNative cardView = (CardViewNative) this.findViewById(R.id.carddemo);
    cardView.setCard(card);

    card.setClickable(true);
    card.setOnClickListener(new Card.OnCardClickListener(){
        @Override
        public void onClick(Card card, View view) {
            // This will execute when the the card is clicked
            Toast.makeText(CardMariotti.this,"Clickable card", Toast.LENGTH_LONG).show();
        }
    });

我进行了调试，但的onClick 方法不会被调用。怎么会呢？

I performed a debug, but the onClick method is never called. How come?

推荐答案

Card.OnCardClickListener是一个接口。必须创建定义了接口中的功能如何被使用的类。试试这个：

Card.OnCardClickListener is an Interface. You must create the class that defines how the functions within the interface are to be used. Try this:

card.setOnClickListener(new Card.OnCardClickListener() {
    @Override
    public void onClick(Card card, View view) {
        // This will execute when the the card is clicked
    }
});

修改

此外，删除的android：点击=真正的通过该卡包含的RelativeLayout的。它偷点击本身。

Furthermore, remove android:clickable="true" from the RelativeLayout contained by the card. It's stealing the click for itself.
