如何以编程方式在Android手机内部存储中打开文件夹？

Answer 1

File folderDirectory = new File(Environment.getDataDirectory()+"/foldername/");

File[] listFiles = fileDirectory.listFiles();

if (listFiles.length != 0) {
    
    for (int indx = 0; indx < listFiles.length; indx++) {
        String fileName = listFiles[indx].toString();
        System.out.println(fileName); 
    }
}
