推荐答案

您可以缓存使用磁盘高速缓存的远程服务的位图，有关于如何做到这一点的谷歌开发者网站的 http://developer.android.com/training/displaying-bitmaps/cache-bitmap.html

You can cache the bitmaps from a remote service using a Disk Cache, there is more information about how to do this on the Google developer site http://developer.android.com/training/displaying-bitmaps/cache-bitmap.html

这将允许你存储的图像，并立即显示如果没有连接，或者您想要加载的图像，同时装载远程图像。

This will allow you to store the images and display immediately if there is no connection, or you want to load the images whilst loading the remote images.

根据您需要存储您可以在缓存或图像或者建立一个ArrayList的数据文本关联，并存储在磁盘什么文字。这里一些细节最佳的方式来缓存数据在Android中

Depending on what text you need to store you can associate the text with the images in the cache or alternatively set up an ArrayList with the data and store to disk. Some more details here Best Way to Cache Data in Android
