有没有办法在Android中以编程方式用密码保护文件夹?
By default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user).

AFAIK, No, you cannot.
You could zip the contents of the folder and store it as an Passworded Zip File. That's the closest solution i can think of. ofcourse, the folder won't exist anymore.
