使用“回收者视图”和“卡片视图”获取轮播的点击位置

Question

I'm using this CarouselView library .

I have used Recycler View and Card View to create the following UI.

In each card view, I have added this carousel view and contains images inside carousel.

This library has the setImageClickListener that gives the index of each clicked image in each card view.

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

I want to know which image is clicked and from which card that image belongs since there are multiple card-views.

I tried to register the click event in the ImageView and get the adapterPosition of clicked cardview using 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.
                }
            });

When both of the events are registered then only click on ImageView ( fruitImageView.setOnClickListener ) gets hit, which gives the position of the adapter. I also want to know which image is clicked.

When I remove this ImageView Click listener, then carousel view click customCarouselView.setImageClickListener gets hit which gives the postion of image clicked but not the adapter position.

Are there any work around for this? Please help.

My Adapter Class complete code:

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();
