    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ls = (ListView) findViewById(R.id.mainlist);

Answer 1

You will need a custom ArrayAdapter and a method that returns all the values that you need from the database, probably a subclass of the SQLiteOpenHelper class. Read about them in detail and eventually you'll know the answer.
