我有存储在特定的文件夹在SD卡中的视频。目前，我有路径作为唯一的参数（例如：SD卡/测试/ sample.mp4），单独使用的URL是否有可能获取图像的缩略图

I have the video which is stored under specific folder in sdcard. Currently i have the path as only parameter(Ex:"sdcard/test/sample.mp4"), by using url alone is it possible to retrieve the thumbnail of the image.

我也想表现出的Andr​​oid视频preVIEW显示，任何一个提供一些例子来做这个事情。

I also want to show the video preview display in android ,any one provide some example to do this thing.

感谢

ThumbnailUtils是用来从任意一个文件系统路径缩略图一个易于使用的API。它是在API 8级可用。

ThumbnailUtils is an easy-to use API for generating thumbnails from arbitrary filesystem paths. It is available in API level 8.

查看ThumbnailUtils.createVideoThumbnail:

Bitmap thumb = ThumbnailUtils.createVideoThumbnail(path,
    MediaStore.Images.Thumbnails.MINI_KIND);
