Start new activity when swiping on a ListView

I have an app in which, the main page, is 100% occupied by a ListView that contains an ArrayList of objects. My goal is that when I slide my finger from right to left on that ListView, I will go to a new window (activity).

I was guided by this tutorial: link and if I reduce the size of the ListView to be able to touch the "background "on the screen, it works. How could I make it detect that glide on the ListView?

My relevant code in the MainActivity class:

public class MainActivity extends AppCompatActivity {

    private GestureDetectorCompat gestureDetector;

    ListView character_list;

@Override
    protected void onCreate(Bundle savedInstanceState) {


        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        if (audios_megumin.isEmpty()) {
            fill_audios_list();
        }
        if (anime_characters_list.isEmpty()) {
            fill_anime_character_list();
        }

        gestureDetector = new GestureDetectorCompat(this, new LearnGesture());

        character_list = findViewById(R.id.list_view_main_characters);
        character_list.setAdapter(new CharacterListAdapter(this, R.layout.main_list_item, anime_characters_list));
//        character_list.setAdapter(new Adapter(this, anime_characters_list));


        character_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView parent, View view, int position, long id) {

                AnimeCharacter anime_character = anime_characters_list.get(position);
                Intent intent = new Intent(getBaseContext(), CharacterAudiosActivity.class);
                intent.putExtra("ANIME_CHARACTER", anime_character);
                startActivity(intent);
            }
    });

    }
            @Override
            public boolean onTouchEvent(MotionEvent event){
                this.gestureDetector.onTouchEvent(event);
                return super.onTouchEvent(event);
            }

    class LearnGesture extends GestureDetector.SimpleOnGestureListener{
        @Override
        public boolean onFling(MotionEvent event1, MotionEvent event2, float velocityX, float velocityY){
            if (event1.getX() > event2.getX()){
                Intent intent = new Intent(
                        MainActivity.this, DonationActivity.class);
                startActivity(intent);
            }
            return true;
        }
    }

There is some way to detect the displacement on the listview (or one of its items since the new activity does not vary depending on these)
