我正在尝试在 recycleview android 中从 cardview 共享和保存 imageview。我的 imagview 是一个静态文件，我想将此文件保存在 android 库中，并在单击共享图像按钮时共享此图像。请看下面的快照！ 在此处输入图像描述

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();


                    }
                });

            }
        }
    });
}
}

我解决了我的问题:)

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

                share_st_img.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 GET Successfully",    Toast.LENGTH_LONG).show();
                        //share image code
                        Intent shareIntent = new Intent(Intent.ACTION_SEND);
                        Uri photoUri = Uri.parse(ImagePath);
                        shareIntent.setData(photoUri);
                        shareIntent.setType("image/png");
                        shareIntent.putExtra(Intent.EXTRA_STREAM, photoUri);
                        context.startActivity(Intent.createChooser(shareIntent, "Use this for sharing"));
                    }
                });

                save_img.setOnClickListener(new View.OnClickListener() {

                        ImagePath = MediaStore.Images.Media.insertImage(
                                context.getContentResolver(),
