Thanks for the reply. The code provided in theead did not help and display nothing in imageview. I will appreciate if you share sample code to achieve the same in android,Thanks. — Rauf Abid, Oct 10 '16 at 18:42

I resolved what i needed. Writing the code following if it helps someone, thanks.

   Bitmap bm = StringToBitMap(GetString);
   MyPhoto.setImageBitmap(bm);   //MyPhoto is image control.
}

public Bitmap StringToBitMap(String encodedString) {
    try {
        byte[] encodeByte = Base64.decode(encodedString, Base64.DEFAULT);
        Bitmap bitmap = BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
        return bitmap;
    } catch (Exception e) {
        e.getMessage();
        return null;
    }
}

Assume that you store your image in an Arraylist or database in like R.drawable.bucket in string form.

Then you can retrieve the image from the string using the following method:

Field declaredField;
declaredField = R.drawable.class.getDeclaredField( mTrafficSignalList.get(i)
    .getImagePath()
    .split("\\.")[2]);
MyViewHolder.image_traffic_sign_textview.setImageResource(declaredField.getInt(declaredField));
