JSON数据解析拿到其中的一个属性

[Ryanly_z]

[{"numValue":1,"color":"","isUpload":"","otherType":3,"content":"住宅","type":2},{"numValue":2,"color":"","isUpload":"","otherType":3,"content":"别墅","type":2},{"numValue":3,"color":"","isUpload":"","otherType":3,"content":"写字楼","type":2},{"numValue":4,"color":"","isUpload":"","otherType":3,"content":"商铺","type":2},{"numValue":5,"color":"","isUpload":"","otherType":3,"content":"小产权","type":2},{"numValue":6,"color":"","isUpload":"","otherType":3,"content":"厂房","type":2},{"numValue":7,"color":"","isUpload":"","otherType":3,"content":"其他","type":2}]
这是我从自己缓存中那到的一段JSON数据，使用hiJosn校验如图：

现在我只想拿到其中的content属性并存到集合中要怎么做？
我使用如下代码转换失败，

  try {
                JSONObject jsonObject = new JSONObject(response.get(2).getData());
                int jsonStr = jsonObject.length();
                LogUtils.d("json", jsonStr+"");
                for (int i = 0; i < jsonStr; i++) {
                    LogUtils.d("json", jsonObject.getString("content"));
                }
            } catch (JSONException e) {
                LogUtils.d("json", "失败");
                e.printStackTrace();
            }

log只打印出了“失败”
求各路高手帮忙
