Android以私人模式将照片保存在磁盘上 [英] Android save photo on disk in private mode

问题描述

我可以使用:将图像保存在磁盘中

I'm able to save a Image in disk using :

String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
        String fileName = imageId + ".png";
        String filePath = baseDir + File.separator + fileName;

        File file = new File(filePath);
        if(!file.exists())
        {
            out = new FileOutputStream(baseDir + File.separator + fileName);
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
        }

但是所有保存的图像都可以在手机的图库中看到..如何将其隐藏给用户?是否有我的私人文件夹?

But all the images saved are visible in the gallery of the phone .. How can I hide them to the user ? Is there a private folder for my appliaction ?

谢谢

推荐答案

public File getAlbumStorageDir(Context context, String albumName) {
    // Get the directory for the app's private pictures directory. 
    File file = new File(context.getExternalFilesDir(
            Environment.DIRECTORY_PICTURES), albumName);
    if (!file.mkdirs()) {
        Log.e(LOG_TAG, "Directory not created");
    }
    return file;
}
