向图像添加元数据

Question

我想在点击图像时向图像添加元数据，例如日期，所用时间以及用户可以添加自己的笔记的描述部分。

if (requestCode == GALLERY_IMAGE_REQUEST && resultCode == RESULT_OK && data != null)
    {
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        imageUri = data.getData();
        File imagesFolder = new File(Environment.getExternalStorageDirectory(), bubbleName);
        imagesFolder.mkdirs();

        File destFile = new File(imagesFolder, "bodypart_" + timeStamp + ".png");
        try {
            copyFile(new File(getPath(imageUri)), destFile);
            imagegrid.setVisibility(View.GONE);
            preview.setVisibility(View.VISIBLE);
            finsihBtn.setVisibility(View.VISIBLE);
            removeBtn.setVisibility(View.VISIBLE);
            Picasso.with(this).load(imageUri).into(preview);

            getPhotosList(bubbleName);
            //imageAdapter.notifyDataSetChanged();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
