String DNAME="1_2_5_7_12";
if(DNAMES.length()>0){
  String[] arr_drivers = DNAMES.split(",");

try as using Pattern.compile for split String to Array:

   String str = "1_2_5_7_12_";
   String[] strarray=Pattern.compile("-").split(str);

and for storing or retrieve value from SharedPreferences see

http://developer.android.com/guide/topics/data/data-storage.html#pref

  String s = "1_2_5_7_12_";

  SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
  Editor edit = preferences.edit();
  edit.putString("pref_str", s); 
  edit.commit();//storing
  // Retrieve
  String pref_numstr =  preferences.getString("pref_str", "n/a");
  ar = pref_numstr.split("_");
  System.out.println(ar.length);

For saving string you can use SharedPreferences or string.xml file. For splitting the string 

String text = "1_2_5_7_12_";
String[] splits = text.split("_");

Save like this:

SharedPreferences prefs = getApplicationContext().getSharedPreferences("prefs", Context.MODE_PRIVATE);
Editor prefsEditor = prefs .edit();
prefsEditor.putString("myString", "1_2_5_7_12");
prefsEditor.commit();

and retrieve like this:

String str= prefs.getString("myString", "");

after that you can split your string simply by doing

String[] strArr = str.split("_");

you can do by this..

            final SharedPreferences pref1 = getSharedPreferences("My_App", MODE_PRIVATE);
            SharedPreferences.Editor editor = pref1.edit();

            editor.putString("str", "yourString");
            editor.commit();

Eventually it's gonna be a string, so i do not see any problem to store it in Sharedpreference . And you can split it as in @Shreya Shah's response

to save 

SharedPreference.edit().putString(value, default).commit()

to get value

SharedPreference.getString(value, default)

to split the string

String.split("_") to split

You can split the string :

String myString = "1_2_5_7_12_";
String numbers[] = myString.split("_");
int num[] = new int[numbers.length];
int i=0;
for(String s : numbers){
   num[i] = Integer.parseInt(s);
   i++;
}

So now the array num will contain integers in that string.
