使用“回收者视图”和“卡片视图”获取轮播的点击位置

Question

我正在使用这个CarouselView库 。

我已经使用了Recycler View和Card View来创建以下UI。

在每个卡片视图中，我都添加了该轮播视图，并在轮播中包含图像。

该库具有setImageClickListener ，该setImageClickListener给出了每个卡片视图中每个单击的图像的索引。

customCarouselView.setImageClickListener(new ImageClickListener() {
        @Override
        public void onClick(int position) {
            Toast.makeText(SampleCarouselViewActivity.this, "Clicked item: "+ position, Toast.LENGTH_SHORT).show();
        }
    });

我想知道单击的图像以及该图像属于哪个卡，因为存在多个卡视图。

我试图注册在ImageView的click事件，并获得adapterPosition点击cardview的使用getAdapterPosition()

fruitImageView.setOnClickListener(new View.OnClickListener() {   /*Hits only when another click event (setImageClickListner) is not registered*/
                @Override
                public void onClick(View view) {
                    int a = getAdapterPosition(); //gives the index of clicked cardview position.
                }
            });

当两个事件都注册时，则仅单击ImageView（ fruitImageView.setOnClickListener ）会被命中，这将给出适配器的位置。 我也想知道单击了哪个图像。

当我删除此ImageView Click侦听器时，然后轮播视图单击customCarouselView.setImageClickListener会被命中，它给出了单击的图像的位置，而不是适配器的位置。

有什么解决办法吗？ 请帮忙。

我的适配器类的完整代码：

public class GridAdapter extends RecyclerView.Adapter<GridAdapter.ViewHolder> {
private ArrayList<HomeSalesModel> salesLists;
int[] sampleImages = {R.drawable.album1, R.drawable.album2, R.drawable.album3, R.drawable.album4, R.drawable.album5};
String[] sampleTitles = {"A", "B", "C", "D", "E"};
Context myContext = null;

public GridAdapter(ArrayList<HomeSalesModel> salesLists) {
    this.salesLists = salesLists;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    myContext = parent.getContext();
    return new ViewHolder(LayoutInflater.from(parent.getContext()), parent);
}

@Override
public void onBindViewHolder(GridAdapter.ViewHolder viewHolder, int i) {
    viewHolder.tv_country.setText(salesLists.get(i).getTitle());
}

@Override
public int getItemCount() {
    return salesLists.size();
}

public class ViewHolder extends RecyclerView.ViewHolder {
    private CarouselView customCarouselView;
    private TextView tv_country;
    private CardView cardView;

    public ViewHolder(LayoutInflater inflater, ViewGroup parent) {
        super(inflater.inflate(R.layout.grid_card_row, parent, false));
        tv_country = (TextView) itemView.findViewById(R.id.tv_country);
        customCarouselView = (CarouselView) itemView.findViewById(R.id.customCarouselView);
        cardView = (CardView) itemView.findViewById(R.id.card);
        customCarouselView.setPageCount(sampleImages.length);
        //customCarouselView.setSlideInterval(4000);
        customCarouselView.setViewListener(viewListener);
        customCarouselView.setImageClickListener(imageClickListner);
    }

    ViewListener viewListener = new ViewListener() {
        @Override
        public View setViewForPosition(int position) {

            LayoutInflater li = (LayoutInflater) myContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View customView = li.inflate(R.layout.view_custom, null);

            TextView labelTextView = (TextView) customView.findViewById(R.id.labelTextView);
            ImageView fruitImageView = (ImageView) customView.findViewById(R.id.fruitImageView);
            fruitImageView.setImageResource(sampleImages[position]);
            labelTextView.setText(sampleTitles[position]);
            fruitImageView.setOnClickListener(new View.OnClickListener() {   /*Works when another click event (imageClickListner) is not registered*/
                @Override
                public void onClick(View view) {
                    int a = getAdapterPosition(); //gives the index cardview position.
                }
            });
            //labelTextView.setText(salesLists.get(position).getProducts().get(position).getSlug());
            return customView;
        }
    };

    ImageClickListener imageClickListner = new ImageClickListener() {
        @Override
        public void onClick(int position) {
            Toast.makeText(myContext, "Clicked item: " + position, Toast.LENGTH_SHORT).show();  //gives index the clicked image.
        }
    };
}

}

只需获得适配器在ImageClickListener位置ImageClickListener 。

int postion = getAdapterPosition();
