android - How to show only non-hidden folders programmatically -

so have simple method helps list all of files in directory (hidden and non-hidden) , wish edit display only non hidden files.

 public arraylist<string> getfiles(string directorypath) {         arraylist<string> myfiles = new arraylist<string>();         file file = new file(directorypath);          //you create array list         //the public final field length, contains number of components of array         file.mkdirs();         file[] files = file.listfiles();         //list of files in array         if (files.length == 0)             //if there no files, return null             return null;         else {             //if number of files greater 0, add files , names             (int = 0; < files.length; i++)                 myfiles.add(files[i].getname());         }          return myfiles; 

how can modify above code display non hidden files?

by way, inserting . in front of file name hides file.

thank you.

you should able make use of ishidden(). refer docs here.

//if number of files greater 0, add files , names         (int = 0; < files.length; i++) {             if(!files[i].ishidden())                  myfiles.add(files[i].getname()); // add non hidden files         }
