如何在Android上将Google云端硬盘与Picasso集成？

概述我正在编写一个应用程序,将图像存储在Google云端硬盘中,我想显示这些图库(GridView).为了更高效(即异步),我想将其与毕加索结合起来.但是Picasso.load(String)只是一个加载的别名(Uri.parse(path)),我没有Uri,因为图像是这样加载的(简化和未公开的实用程序方法)： public static Bitmap getBitmap(DriveId id) { 我正在编写一个应用程序,将图像存储在Google云端硬盘中,我想显示这些图库(GrIDVIEw).为了更高效(即异步),我想将其与毕加索结合起来.但是Picasso.load(String)只是一个加载的别名(Uri.parse(path)),我没有Uri,因为图像是这样加载的(简化和未公开的实用程序方法)：

public static Bitmap getBitmap(DriveID ID) {    Googleapiclient clIEnt = apiclientAsyncTask.createConnectedClIEnt(App.getAppContext());    Drivefile file = Drive.DriveAPI.getfile(clIEnt,ID);    Metadata Meta = sync(file.getMetadata(clIEnt));    Contents contents = sync(file.openContents(clIEnt,Drivefile.MODE_READ_ONLY,null));    inputStream imagestream = contents.getinputStream();    try {        return BitmapFactory.decodeStream(imagestream);    } finally {        IOTools.ignorantClose(imagestream);        sync(file.discardContents(clIEnt,contents));    }}

是否有任何其他类似的库可能支持任意输入(String / Object)的集成？

当然我想在Picasso中使用缓存(网络(上面的方法),磁盘,内存)的完全支持.

解决方法 当时毕加索的版本不支持我想要的东西所以我去使用了 Glide 3.这就是我设法放在一起的东西.
我还没有测试它,我把它从历史中拼凑起来,因为我从我的应用程序中删除了这个支持,这是一个过度杀伤力;但是当功能仍然存在时,它正在工作.

在ConnectionCallbacks.onConnected中：

GlIDe.get(getContext()).register(DriveID.class,inputStream.class,new DriveIDModelLoader.Factory(mClIEnt));

在ConnectionCallbacks.onConnectionSuspended中：

GlIDe.get(getContext()).unregister(DriveID.class,inputStream.class);

在列表适配器：

String driveString = cursor.getString(cursor.getColumnIndex("image"));DriveID driveID = DriveID.decodeFromString(driveString);GlIDe.with(this)     .from(DriveID.class)     .load(driveID)     .into(imageVIEw);
