在我的应用程序，我最初加载从画廊，即（MediaStore.Images.Media.EXTERNAL_CONTENT_URI）所有影像

in my app, i initially load all the images from the gallery, i.e. (MediaStore.Images.Media.EXTERNAL_CONTENT_URI)

用户可以通过我的应用程序拍照，但我有一个自定义的摄像头，也就是我不使用默认的手机摄像头拍照，我有我自己的表面来看，我处理Camera对象直接，处理摄像头的画面。我保存这个形象在自定义文件夹。

user can take picture via my app, but i have a custom camera, i.e. i do not use default phone camera to take pictures, i have my own surface view, i deal with Camera object directly, and handle the camera picture. and i save this image in a custom folder.

我想在新拍摄的照片出现在我的画廊，一旦用户返回到我的应用程序

i want the newly taken picture to appear in my gallery once user returns to my app

问题： 新拍摄图像没有出现在光标我装入MediaStore.Images.Media.EXTERNAL_CONTENT_URI

problem: the newly taken picture does not appear in the cursor i loaded with MediaStore.Images.Media.EXTERNAL_CONTENT_URI

这个问题只走了，当我重新安装应用程序，并强制重新扫描。

the problem is gone only when i reinstall the app and force a rescan.

我该如何解决这一问题？我想，立即采取会出现在我的光标每一个画面？

how do i fix this? i want every picture that was immediately taken will appear in my cursor?

我已经做了一些researhc，但不要告诉我contentvalues​​中包含

i have done some researhc, but don't tell me the contentvalues with the startactivity solution like below

 startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

这是不行的，因为再次，我有我自己的相机，我不使用默认的摄像头活动从手机

this does not work, because again, i have my own camera, i am not using the default camera activity from the phone

我也试过

 getContentResolver().notifyChange(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null);

这也不行

有人可以帮忙吗？

感谢

推荐答案

您只需要发送一个广播ACTION_MEDIA_SCANNER_SCAN_FILE，这样的mediascanner可以为你保存的图像扫描。

You just need to send an broadcast "ACTION_MEDIA_SCANNER_SCAN_FILE" so that the mediascanner can scan for the image you saved.

 Intent mediaScanIntent = new Intent( Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
 mediaScanIntent.setData(uri);
 sendBroadcast(mediaScanIntent);

刚刚成立的新创建的图像的URI。 ：）

just set the uri of the the newly created image. :)
