获取文件路径下的所有子文件夹android kotlin

import java.io.File

fun getAllSubfolders(path: String): List<String> {
    val subfolders = mutableListOf<String>()
    val rootFolder = File(path)

    if (rootFolder.exists() && rootFolder.isDirectory) {
        val files = rootFolder.listFiles()
        if (files != null) {
            for (file in files) {
                if (file.isDirectory) {
                    subfolders.add(file.absolutePath)
                    subfolders.addAll(getAllSubfolders(file.absolutePath))
                }
            }
        }
    }

    return subfolders
}

// 使用示例
val folderPath = "/sdcard/your_folder_path"
val subfolders = getAllSubfolders(folderPath)
for (subfolder in subfolders) {
    println(subfolder)
}
