我如何prevent从添加到库中的重复的图片？ [英] How do I prevent a duplicate picture from adding to the gallery?

问题描述

我用下面的code拍摄照片：

I use the following code to take a picture:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(path + "/" + fileName)));
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

现在，当我用这个，但是它保存在我上面指定的图片，而且还节省了第二个副本到默认图像文件夹并将其添加到库中。

Now when I use this, it does save the picture where I specify above, but it also saves a second copy to the default image folder and adds it to the gallery.

我想简单地删除第二个文件，但它似乎的onActivityResult的意图参数始终以表示照片后空那将是一点点危险的，所以我会尝试删除最近保存的图片。

I would simply delete the second file, but it seems it would be a tad dangerous as onActivityResult's intent parameter is always null after taking said picture, so I would have to attempt deleting the most recently saved picture.

有什么办法，我可以prevent这种行为，或通过获取dupicate图片的URI纠正呢？

Is there any way I can prevent this behavior or correct it by getting the URI of the dupicate picture?

推荐答案

嗯，我已经决定了它是pretty很多不可能的。我现在用的是SurfaceView用我自己的相机活动。

Well I've determined that it is pretty much not possible. I am now using a SurfaceView with my own camera activity.
