无法将相机拍摄的照片保存在应用程序的“文件"中文件夹 [英] Can not save camera's captured photo in application's "files" folder

问题描述

我在应用程序的内部存储文件"文件夹中创建了一个名为"myImage"的文件夹.当我用相机拍摄照片时，我希望将照片保存在"files/myImage"文件夹中.似乎相机没有权限在该文件夹中写入内容，因为该文件夹仍然为空.另一方面，当我在外部存储中创建"myImage"文件夹时，照片将正常保存.

I create a folder called "myImage" in my application's Internal Storage "files" folder. When i take a photo with the camera i want the photo to be saved in "files/myImage" folder. It seems that the camera has not the permsission to write in that folder because the folder remains empty. On the other hand, when i create "myImage" folder in the external storage, the photo is saved normally.

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
UUID myPhotoGuid = UUID.randomUUID();
myPhotoName = myPhotoGuid.toString();

String dirPath = getActivity().getFilesDir().getAbsolutePath() + File.separator + "myImage";
File myPhotoDirectory = new File(dirPath);
myPhotoDirectory.mkdir();

File f = new File(myPhotoDirectory.toString(), myPhotoName);                    

                // Save the captured image in f file
                intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));                    
                startActivityForResult(intent, CAPTURE_IMAGE);

可能是什么问题? 有没有办法更改文件夹的权限?

What could be wrong? Is there a way to change folder's permissions?

提前谢谢！

推荐答案

使用getExternalFilesDir代替getFilesDir.

Instead of getFilesDir use getExternalFilesDir.

您可能还需要添加一些权限:

You might also need to add some permissions:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
