在 Recycleview 中保存和共享来自 Cardview 的 ImageView Android

Question

我正在尝试在 recycleview android 中共享和保存来自 cardview 的图像视图。我的 imagview 是一个静态文件，我想将此文件保存在 android 图库中，并在我单击共享图像按钮时共享此图像。请看下面的快照！

我的代码在下面！

public class PicCardViewHolder extends RecyclerView.ViewHolder {

public TextView pic_name;
public ImageView st_image;
public ImageView save_img;
public ImageView share_st_img;
public Drawable drawable;
public Bitmap bitmap;
public String ImagePath;
public Uri URI;

public Context context;


public PicCardViewHolder(View v) {
    super(v);
    context = itemView.getContext();
    pic_name = (TextView) itemView.findViewById(R.id.pic_name);
    st_image = (ImageView) itemView.findViewById(R.id.st_pic);
    save_img = (ImageView) itemView.findViewById(R.id.down_img);
    share_st_img = (ImageView) itemView.findViewById(R.id.share_pic_st);

    v.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            int pos = getAdapterPosition();
            if (pos == 0) {

                 //code for save image into gallery android
                st_image.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {

                        drawable = ContextCompat.getDrawable(context, R.drawable.test_image);
                        bitmap = ((BitmapDrawable) drawable).getBitmap();
                        ImagePath = MediaStore.Images.Media.insertImage(
                                context.getContentResolver(),
                                bitmap,
                                "demo_image",
                                "demo_image"
                        );

                        URI = Uri.parse(ImagePath);
                        Toast.makeText(context, "Image Saved Successfully", Toast.LENGTH_LONG).show();


                    }
                });

            }
        }
    });
}
}

    v.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            int pos = getAdapterPosition();
            if (pos == 0) {

                share_st_img.setOnClickListener(new View.OnClickListener() {
