我使用 MediaStore.Images.Thumbnails 来显示用户拥有的图像。但我无法通过其路径获取图像。有什么方法可以使用路径查找图像吗？

String [] proj={MediaStore.Images.Thumbnails._ID, MediaStore.Images.Thumbnails.IMAGE_ID, MediaStore.Images.Media.DATA};  
String selection =  MediaStore.Images.Media.DATA + " like '%path%'";  //this doesn't work  
cursor = managedQuery( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
                       proj, // Which columns to return   
                       selection,       // WHERE clause;   
                       null,        
                       null); // Order-by clause

此致！

I'm using MediaStore.Images.Thumbnails in order to show the images the user have. But i'm not able to get an image through its path.
Is there any way to look for an image using the path?

String [] proj={MediaStore.Images.Thumbnails._ID, MediaStore.Images.Thumbnails.IMAGE_ID, MediaStore.Images.Media.DATA};  
String selection =  MediaStore.Images.Media.DATA + " like '%path%'";  //this doesn't work  
cursor = managedQuery( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
                       proj, // Which columns to return   
                       selection,       // WHERE clause;   
                       null,        
                       null); // Order-by clause

Best regards!

嗨，

//I just get Image ID.

String [] proj={MediaStore.Image.Media._ID,MediaStore.Image.Media.DATA}
cursor=manageQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj,MediaStore.Images.Media.DATA+"= ' "+path+" ' ",null,null);
cursor.moveToFirst();

// and then, use ID to get thumbnails

Bitmap b=MediaStore.Images.Thumbnails.getThumbnail(cr,Integer.valueOf(cursor.getString(0)),kind, null);

// or for video

Bitmap b=MediaStore.Video.Thumbnails.getThumbnail(cr, Integer.valueOf(cursor.getString(0)),kind, null);

BR，
