解决方案

画廊与MediaStore内容提供商进行交互。如果更改图像文件的名称，你可能需要在内容提供商来更新字段。

您可以在MediaStore参考读了它：的http://developer.android.com/reference/android/provider/MediaStore.Images.Media.html

潜在你可以触发MediaStore的刷新。看看这些线：我怎样才能刷新MediaStore在Android <？ / p>

I am trying to rename an image in Gallery taken from Camera to give a new name. When I renamed the file the original image disappears showing 2 black squares . Can any one help me in sorting this issue by telling me procedure to rename Gallery Image.

Path is as follows : /mnt/sdcard/DCIM/Camera

I tried to update the Image title through content provider as below:

ContentValues val = new ContentValues();
val.put(Images.Media.TITLE, "ImageTitle23");
getContentResolver().update(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, val, null, null);

The image title is changed in Gallery.

But when I try to query the updated image as below I am getting the name same as previous one :

final String[] imageColumns = { MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA };
final String imageOrderBy = MediaStore.Images.Media._ID+" DESC";   
Cursor imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns, MediaStore.Images.Media._ID+"="+id, null, imageOrderBy);  
if(imageCursor.moveToFirst()){    
  int idd = imageCursor.getInt(imageCursor.getColumnIndex(MediaStore.Images.Media._ID)); 
  String fullPath = imageCursor.getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA)); 

Can anyone help me in sorting out this issue?

解决方案

The Gallery is interacting with the MediaStore content provider. If you change the name of the image file you probably need to update the field in the content provider.

You can read up on it in the MediaStore reference : http://developer.android.com/reference/android/provider/MediaStore.Images.Media.html

Potentially you can just trigger a refresh of the MediaStore. Look at this thread : How can I refresh MediaStore on Android?
