当我单击项目时,我现在有50个绿色的recyclerview项目
它变成红色,当我再次单击时又变成绿色,下面是代码如何实现的代码

public void onBindViewHolder(final RecyclerView.ViewHolder holder, int position) {

    if (holder instanceof ItemViewHolder) {
        ((ItemViewHolder)holder).Title.setText(position+1+"");
        ((ItemViewHolder)holder).imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (status==0){
                    status=1;
                    ((ItemViewHolder) holder).imageView.setImageResource(R.drawable.ic_social_person);//red icon
                }else {
                    status=0;
                    ((ItemViewHolder) holder).imageView.setImageResource(R.drawable.ic_social_person_green);//green icon
                }

            }
        });


    } else {
        ((progressHolder) holder).progressBar.setIndeterminate(true);
    }


}


现在的问题是,当我单击第一项时它变成红色图标,但是当我单击第二项时它没有变成红色图标,当我第二次再次单击时它变成红色图标如何解决这个问题

最佳答案

 public SparseBooleanArray array = new SparseBooleanArray();
    public void onBindViewHolder(final RecyclerView.ViewHolder holder, final int position) {

        if (holder instanceof ItemViewHolder) {
            ((ItemViewHolder)holder).Title.setText(position+1+"");
            ((ItemViewHolder)holder).imageView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    boolean status = array.get(position);
                    if (!status){
                        array.put(position,!status);
                        ((ItemViewHolder) holder).imageView.setImageResource(R.drawable.ic_social_person);//red icon
                    }else {
                        array.put(position,!status);
                        ((ItemViewHolder) holder).imageView.setImageResource(R.drawable.ic_social_person_green);//green icon
                    }

                }
            });


        } else {
            ((progressHolder) holder).progressBar.setIndeterminate(true);
        }


    }
