从android studio内部存储中删除列表

String fileName = "list.txt"; // 列表文件名
File file = new File(getFilesDir(), fileName); // 获取文件路径
boolean deleted = file.delete(); // 删除文件
if (deleted) {
    // 文件删除成功的处理逻辑
} else {
    // 文件删除失败的处理逻辑
}

String directoryName = "list_directory"; // 列表目录名
File directory = new File(getFilesDir(), directoryName); // 获取目录路径
boolean deleted = deleteDirectory(directory); // 删除目录
if (deleted) {
    // 目录删除成功的处理逻辑
} else {
    // 目录删除失败的处理逻辑
}

private boolean deleteDirectory(File directory) {
    if (directory.isDirectory()) {
        File[] files = directory.listFiles();
        if (files != null) {
            for (File file : files) {
                deleteDirectory(file);
            }
        }
    }
    return directory.delete();
