如何在Android CardView上添加滑动功能？

我有一个包含两个TextView和两个ImageView的CardView.我希望能够向左和向右滑动以"解雇".我实际上想要向右滑动以发送一个Intent,但这可以在以后完成.现在,我希望能够通过向左或向右滑动来解除CardView.我也想要滑动动画.

我试过使用,romannurik's SwipeDismissTouchListener但CardView没有响应刷卡.

如果有人有比romannurik's自定义监听器更好的解决方案,请分享.

这是我的CardView布局:

我如何设置SwipeDismissTouchListener:

RelativeLayout rootLayout;
CardView restaurantCardView;

...

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        rootLayout = (RelativeLayout) inflater.inflate(R.layout.fragment_main, container, false);

        restaurantCardView = (CardView) rootLayout.findViewById(R.id.restaurantContainer);

        restaurantCardView.setOnTouchListener(new SwipeDismissTouchListener(restaurantCardView, null, new SwipeDismissTouchListener.DismissCallbacks() {
            @Override
            public boolean canDismiss(Object token) {
                Log.d("Chris", "canDismiss() called with: " + "token = [" + token + "]");
                return true;
            }

            @Override
            public void onDismiss(View view, Object token) {
                Log.d("Chris", "onDismiss() called with: " + "view = [" + view + "], token = [" + token + "]");
            }
        }));
    ....

    return rootLayout;

我能够看到日志canDismiss(...)而不是来自onDismiss(...).

你必须把它放在里面RecyclerView(你CardView作为唯一的项目)

然后,使用ItemTouchHelper.SimpleCallback来itemTouchHelper.attachToRecyclerView(recyclerView);

它会给你动画和

@Override
public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
}

您可以根据滑动方向指定特定操作.

请参阅此处的完整说明:向RecyclerView滑动至关闭

此外,您还必须禁用垂直滚动RecyclerView:

public class UnscrollableLinearLayoutManager extends LinearLayoutManager {
    public UnscrollableLinearLayoutManager(Context context) {
        super(context);
    }

    @Override
    public boolean canScrollVertically() {
        return false;
    }
}

.....

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new UnscrollableLinearLayoutManager(this));
recyclerView.setAdapter(new RestaurantCardAdapter());

否则 - 一旦你试图向上或向下滚动 - 你会看到RecyclerView列表末尾的动画.

UPD:

这是RecyclerView.Adapter我用来测试的:

private class RestaurantCardAdapter extends RecyclerView.Adapter {
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new RestaurantViewHolder(new RestaurantCard(parent.getContext()));
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {}

    @Override
    public int getItemCount() {
        return 1;
    }

    private class RestaurantViewHolder extends RecyclerView.ViewHolder {
        public RestaurantViewHolder(View itemView) {
            super(itemView);
        }
    }
}

RestaurantCard- 只是一个习惯View(CardView在我们的例子中扩展):

public class RestaurantCard extends CardView {
    public RestaurantCard(Context context) {
        super(context);
        initialize(context);
    }

    public RestaurantCard(Context context, AttributeSet attrs) {
        super(context, attrs);
        initialize(context);
    }

    private void initialize(Context context){
        LayoutInflater.from(context).inflate(R.layout.card, this);
        // ImageView imageView = (ImageView)getView.findViewById(...);
    }
}
