Answer 1

Remove the "score=" part of each line in the text file, and for each line check if the remaining content is a valid number - if so, store that as an integer in a collection. Once you're done with reading the text file, you can just sort the collection and use the data in whatever fashion you want in your TextView.

Answer 2

You can do the following Scanner Reader=new Scanner(fileName); In a for loop read all the integers from using Reader.nextInt() function.
