图片权限（不要在图库中使用它们） [英] image permissions (don't want them in gallery)

问题描述

我正在开发一个将其图像存储在Android / data文件夹中的应用程序。
图片在图库中可见，但我不想这样。

I'm working on a application which stores its images in the Android/data folder. The pictures are visible in the gallery, but I don't want that.

是否可以设置文件夹的权限，以便只能使用它们应用程序本身，还是应该将它们存储在另一个文件夹中？

Is it possible to set permissions on a folder so they can only be used by the application itself, or should I just store them in another folder?

推荐答案

创建一个名为的文件文件夹中的.nomedia 。这会将它们隐藏在图库应用程序中。

Create a file called .nomedia in the folder. That'll hide them from the gallery application.

以下是如何在Java代码中执行此操作：

Here's how to do it in Java code:

File nomedia = new File(dataFolder, ".nomedia");
try {
    nomedia.createNewFile();
} catch (IOException e) {
    e.printStackTrace();
}
