List<Row> result = new ArrayList<Row>(); 
    for (int i = 0; i < array.length(); i++) { 
     try { 
     result.add(new Row(array.getJSONObject(i).getString("thumbnail"))); 
     } catch (JSONException e) { 
        e.printStackTrace(); 
    } 
    } 

     return result;

Answer 1

 String[] qwe = row.thumbs.toArray(new String[row.thumbs.size()]); 
     loader.displayImage(qwe[position], image, options); 

你肯定qwe至少包含postion + 1元素？
