Android Tinder 类似 swipeable-card setOnCardDismissedListener

Question

我正在尝试制作类似火种的可刷卡。我有这个库https://github.com/kikoso/Swipeable-Cards。我跟着演示，它工作正常。但是demo中只有一个cardModel要设置在carddismissedlisterner上。如何让适配器中的所有 cardModels 工作？我想在关闭后获取每个cardModel的信息（例如标题、文本）

private CardContainer mCardContainer;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.mainlayout);

    mCardContainer = (CardContainer) findViewById(R.id.layoutview);

    Resources r = getResources();

    SimpleCardStackAdapter adapter = new SimpleCardStackAdapter(this);

    adapter.add(new CardModel("Title1", "Description goes here", r.getDrawable(R.drawable.picture1)));
    adapter.add(new CardModel("Title2", "Description goes here", r.getDrawable(R.drawable.picture2)));
    adapter.add(new CardModel("Title3", "Description goes here", r.getDrawable(R.drawable.picture3)));
    adapter.add(new CardModel("Title4", "Description goes here", r.getDrawable(R.drawable.picture1)));
    adapter.add(new CardModel("Title5", "Description goes here", r.getDrawable(R.drawable.picture2)));
    adapter.add(new CardModel("Title6", "Description goes here", r.getDrawable(R.drawable.picture3)));
    adapter.add(new CardModel("Title1", "Description goes here", r.getDrawable(R.drawable.picture1)));

    CardModel cardModel = new CardModel("Title1", "Description goes here", r.getDrawable(R.drawable.picture1));
    String title = cardModel.getTitle();
    cardModel.setOnClickListener(new CardModel.OnClickListener() {
       @Override
       public void OnClickListener() {
           Log.i("Swipeable Cards","I am pressing the card");
       }
    });

    cardModel.setOnCardDimissedListener(new CardModel.OnCardDimissedListener() {
        @Override
        public void onLike() {
            Log.i("Swipeable Cards","I like the card");
            datasource.createComment(title);
        }

        @Override
        public void onDislike() {
            Log.i("Swipeable Cards","I dislike the card");
            datasource.deleteComment(title);
        }
    });

    adapter.add(cardModel);

    mCardContainer.setAdapter(adapter);
}

/****************** 更新********************** */ 我尝试在我所有的 cradModels 上重复 setOnCardDismissedListener。如果是 onLike，我想保存 cardModel 的标题。但是，我检查了我的数据库，我确实保存了两次，但两个标题都是“title2”，我想知道为什么“title1”没有保存。

    CardModel cardModel1 = new CardModel("Title1", "Description goes here",
            r.getDrawable(R.drawable.picture1));
    final String title1 = cardModel1.getTitle();

    CardModel cardModel2 = new CardModel("Title2", "Description goes here",
            r.getDrawable(R.drawable.picture1));
    final String title2 = cardModel2.getTitle();
    adapter.add(cardModel1);
    adapter.add(cardModel2);
    cardModel1.setOnClickListener(new CardModel.OnClickListener() {
        @Override
        public void OnClickListener() {
            Log.i("Swipeable Cards", "I am pressing the card");
        }
    });
    cardModel1
            .setOnCardDimissedListener(new CardModel.OnCardDimissedListener() {
                // onLike swipe to left, but we want it to be removed
                @Override
                public void onLike() {
                    Log.i("Swipeable Cards", "I like the card");
                    datasource.createComment(title1);
                }

                // disLike swipe to right, but we want it to be saved
                @Override
                public void onDislike() {
                    Log.i("Swipeable Cards", "I dislike the card");
                }
            });

    cardModel2.setOnClickListener(new CardModel.OnClickListener() {
        @Override
        public void OnClickListener() {
            Log.i("Swipeable Cards", "I am pressing the card");
        }
    });
    cardModel2
            .setOnCardDimissedListener(new CardModel.OnCardDimissedListener() {
                // onLike swipe to left, but we want it to be removed
                @Override
                public void onLike() {
                    Log.i("Swipeable Cards", "I like the card");
                    datasource.createComment(title2);
                }
                // disLike swipe to right, but we want it to be saved
                @Override
                public void onDislike() {
                    Log.i("Swipeable Cards", "I dislike the card");
                }
            });

只需在所有卡型号上重复 setOnCardDimissedListener。

如果界面返回某种标记，您可以为所有卡模型设置一个OnCardDimissedListener，但不幸的是，如果您这样做，您将无法知道对哪张卡进行了操作。

您需要在您创建的每个卡片模型上设置不同的 OnCardDimissedListener 实例。

编辑 - 你有没有看 github 页面？

Additionally, you can set up a Delegate to be notified when the image is being liked or disliked: 

card.setOnCardDimissedDelegate(new CardView.OnCardDimissedDelegate() {
        @Override
        public void onLike(CardView cardView) {
            Log.d("Swipeable Card", "I liked it");
        }

        @Override
        public void onDislike(CardView cardView) {
            Log.d("Swipeable Card", "I did not liked it");
        }
    });

创建OnCardDimissedDelegate 的类实例并将其设置在每张卡片上。
