我需要存储在本地我解雇了最后一次客户端Android应用程序，可以立即使用数据的查询结果。更新后的数据可以稍后从AsyncTack或线程

这是生成的客户端库返回的对象是扩展GenericJson类

有没有办法将它转换成共享preferences一个String和商店，后来又实例化对象？

解决方案

我通过实现一个惊人的库解决了这个问题。

Android的易缓存

使用上述样本库code：

 公共类MainListingsUpdate扩展的AsyncTask＆LT;太虚，太虚，太虚＆GT; {    私人CollectionResponseMainEventListing名单=新CollectionResponseMainEventListing（）;    私人DualCache＆LT; CollectionResponseMainEventListing＆GT;高速缓存;     @覆盖        保护无效doInBackground（虚空......空隙）{            尝试{                。名单= mainActivityConnect.getAppUserApi（）getMainListings（）执行（）;        一下SizeOf＆LT; CollectionResponseMainEventListing＆GT;整型尺寸=新中SizeOf＆LT; CollectionResponseMainEventListing＆GT;（）{                @覆盖                公众诠释整型尺寸（CollectionResponseMainEventListing对象）{                    返回object.toString（）的getBytes（）长度。                }            };        缓存=新DualCacheBuilder＆LT;＆GT;（Constants.cacheName，1，CollectionResponseMainEventListing.class）                    .useReferenceInRam（Integer.MAX_VALUE的，整型尺寸）                    .useDefaultSerializerInDisk（Integer.MAX_VALUE的，真正的）;        cache.put（OBJECT_KEY清单）;            }赶上（IOException异常五）{                queryComplete = FALSE;            }            返回null;        }    } 

和检索，它的那样简单：

  cache.get（OBJECT_KEY）; 

I need to store the results of the query that i fired the last time locally on the client android app for immediately using the data. The updated data can be fetched later from an AsyncTack or a thread

The objects that the generated client libraries return are of class that extends GenericJson

is there any way to convert this into a String and store in sharedpreferences and Later instantiate the Objects again ?

heres the class definition

    public sanket.pinboard.backend.postApi.model.Post clone() { /* compiled code */ }
}

I solved the problem by implementing an amazing library

android-easy-cache

sample code using the above library :

 public class MainListingsUpdate extends AsyncTask<Void, Void, Void> {

    private CollectionResponseMainEventListing list = new CollectionResponseMainEventListing();
    private DualCache<CollectionResponseMainEventListing> cache;

     @Override
        protected Void doInBackground(Void... voids) {
            try {
                list = mainActivityConnect.getAppUserApi().getMainListings().execute();



        SizeOf<CollectionResponseMainEventListing> sizeOf = new SizeOf<CollectionResponseMainEventListing>() {
                @Override
                public int sizeOf(CollectionResponseMainEventListing object) {
                    return object.toString().getBytes().length;
                }
            };

        cache = new DualCacheBuilder<>(Constants.cacheName, 1, CollectionResponseMainEventListing.class)
                    .useReferenceInRam(Integer.MAX_VALUE, sizeOf)
                    .useDefaultSerializerInDisk(Integer.MAX_VALUE, true);

        cache.put("OBJECT_KEY", list);

            } catch (IOException e) {
                queryComplete = false;
            }
            return null;
        }

    }

and to retrieve , its as simple as :

cache.get("OBJECT_KEY");
