            File file = new File(itemList.get(position));
            Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
            Uri data = Uri.parse("file://" + file.getAbsolutePath());
            intent.setDataAndType(data, "image/*");

By using this you can open default Image Viewer

Intent viewImageIntent = new Intent(android.content.Intent.ACTION_VIEW, uri);
startActivity(viewImageIntent);

You can save bitmap to file and show image this code :

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("file://" + filepath), "image/*");
startActivity(intent);
