Codice per slide con barra laterale fissa

Mi salvo il codice:

public class MainActivity extends AppCompatActivity {

    Helper helper;
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        helper=new Helper(this);

        /*helper.save("Mario");
        helper.save("Pasquale");*/

        helper.saveData(1,"Primo");

    }

    class Helper extends SQLiteOpenHelper{

        public Helper(Context context) {
            super(context, "mioDatabase.db", null, 1);
        }

        @Override
        public void onCreate(SQLiteDatabase db) {
            db.execSQL("create table tblNomi(_id integer primary key, nome text)");
            db.execSQL("create table tblDati(_id integer primary key, extKey integer, dato text)");
        }

        public void save(String nome){
            SQLiteDatabase db=this.getWritableDatabase();
            ContentValues values=new ContentValues();
            values.put("nome",nome);
            db.insert("tblNomi",null,values);

        }

        public void saveData(int id, String dato){
            SQLiteDatabase db=this.getWritableDatabase();
            ContentValues values=new ContentValues();
            values.put("extKey",id);
            values.put("dato",dato);
            db.insert("tblDati",null,values);
        }

        public Cursor query(int id){
            SQLiteDatabase db=this.getWritableDatabase();
            Cursor c=db.rawQuery("select * from tblNomi where _id="+id, null);
            c.moveToFirst();
            return c;
        }






        @Override
        public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

        }
    }

}
