You can split the input string based on any special character,in your case ,, as follows

String inputString = "1234,1234,1234,1234";
String[] separated = inputString.split(",");

Log.i("MainActivity",separated[0]) // prints the first string which is 1234

// to loop over all strings
for(String s : separated){
     Log.i("MainActivity",s)
}
