目前我正在创建一个文件夹名称“Raw Image”来保存图像。如果我想在“Raw Image文件夹”中创建更多文件夹，该怎么办？请提出任何建议。

Answer 1

通过这种方式，您将在“Raw Image”文件夹中创建一个名为“another_folder”的文件夹：

File imagesFolder = new File(Environment.getExternalStorageDirectory(), "Raw Image/another_folder");

此外，您应该避免在名称中创建带空格的文件夹/文件

Answer 2

您必须检查文件夹是否已存在。你只需要添加一行代码

File imagesFolder = new File(Environment.getExternalStorageDirectory(), "Punch");

if (!imagesFolder.exists()) {
imagesFolder.mkdirs();
}
else { //do nothing

}

Answer 3

尝试以下代码

File imagesFolder = new File(Environment.getExternalStorageDirectory(), "Raw Image");
File folder= new File(imagesFolder , "yourfolder name");
        folder.mkdirs();
