删除照片缩略图画廊后手动删除该照片文件 [英] Delete photo thumbnail in Gallery after manually delete the photo file

问题描述

case R.id.menu_delete:
    File photoToDelete = new File(photoPath, photoList[gPosition]);
    photoToDelete.delete();
    checkPhotoFolder();
    galleryAdapter.notifyDataSetChanged();
    Log.d("position", "" + gPosition);
    return true;

我是手动使用上述code删除照片文件。但是在系统图库照片仍然显示为空白缩略图。
现在的问题是我怎么能删除的照片文件，也缩略图在画廊？

I'm manually delete a photo file using above code. But in the system gallery the photo still show the blank thumbnail. The question is how can I delete the photo file and also the thumbnail of it in the gallery?

推荐答案

试试这个。

getContentResolver().delete(Uri.fromFile(photoToDelete), null, null);
