How to put only real items in the second Activity?

I'm trying to make a Favorites Activity, I'll follow the example of this guy here . In the second Activity I will create as I would to put these items set as true in a listview? and playing them normally would I have to re-create all the playback code in the second Activity? and then how would I remove them. This is a favorites scheme if anyone knows a good tutorial is already a big help, thank you.

MainActivity.class

public class MainActivity extends AppCompatActivity {

    ListView lv;
    MediaPlayer mp;
    ArrayList<memes> item;
    ArrayAdapter<memes> arrayAdapter;
    String[] Nomes = new String[]{"Compartilhar meme", "Favoritos"};
    List<memes> favoriteMemes= new ArrayList<memes>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(activity_main);

        isStoragePermissionGranted();

        lv = findViewById(R.id.lv);
        mp = new MediaPlayer();

        item = new ArrayList<>();
        //itens
        item.add(new memes("Arnold Musica", R.raw.diffrentstrokes));
        item.add(new memes("Aham sei  ", R.raw.ahamsei));
        item.add(new memes("2 mil anos", R.raw.milanos));
        item.add(new memes("Acelera jesus", R.raw.acelera_jesus));


        arrayAdapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, item);
        lv.setAdapter(arrayAdapter);

        //play audio
        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
                playSong(position);
            }
        });

        lv.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> adapterView, View view, final int position, long l) {
                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                builder.setTitle("Olá, Marilene!");
                builder.setItems(MainActivity.this.Nomes, new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        switch (which) {
                            case 0:
                                sendWhatsAppAudio(position);
                                return;
                            case 1:

                                item.get(position).setmIsFavourite(true);
                                return;
                            default:
                        }
                    }
                });
                builder.show();
                return true;
            }
        });

//Aqui esta a bagunça 
 public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {

case R.id.abreFavoritos:
                for(int i=0;i<lv.getAdapter().getCount();i++){
                    memes fMeme = (memes)lv.getAdapter().getItem(i);
                    //mIsFavourite em meu codigo fica vermelho
                    //o que eu devo colocar depois do item. para que funcione?
                    if (item.mIsFavourite()) {
                        favoriteMemes.add(fMeme);
                    }
                }
                intent = new Intent(this, Favoritos.class);

                intent.putExtra("favoritos", new Gson().toJson(favoriteMemes));
                startActivity(intent);

                return true;
              default:

                return super.onOptionsItemSelected(item);

        }
    }

}

Favorites.class

   public class Favoritos extends AppCompatActivity {
    ListView lv;
    ArrayAdapter<memes> arrayAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(activity_main);

        lv = findViewById(R.id.lv);

        String memesString = getIntent().getStringExtra("favoritos");
        memes[] fMemes = new Gson().fromJson(memesString,memes[].class);

        arrayAdapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, fMemes);
        lv.setAdapter(arrayAdapter);
    }
}

memes.class (Adapter)

public class memes{

    private String nome;
    private int resID;
    private Boolean mIsFavourite;

    public memes(String nome, int resID){

        this.nome = nome;
        this.resID = resID;
    }

    public Boolean getmIsFavourite() {
        return mIsFavourite;
    }

    public void setmIsFavourite(Boolean mIsFavouriteResource) {
        this.mIsFavourite = mIsFavouriteResource;
    }

    public String getNome(){
        return nome;
    }

    public int getResId(){
        return resID;
    }

    @Override
    public String toString(){
        return nome;
    }

}

It seems like I'm well behind the goal, if I do not have time to tell tutorials or links that I need to study to do this.
