Question

Android

Help good people ...
What method can I transfer objects from 1 listview to another, located in another activity?

public class Korzina extends AppCompatActivity
        implements NavigationView.OnNavigationItemSelectedListener, View.OnClickListener {
    private SwipeLayoutAdapterKorz mAdapter;
    private ListView mListView;
    Korz mData= new Korz();
    ImageButton button,button2,button3;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_korzina);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        button = (ImageButton) findViewById(R.id.button);
        button2 = (ImageButton) findViewById(R.id.button2);
        button3 = (ImageButton) findViewById(R.id.button3);
        button.setOnClickListener(this);
        button2.setOnClickListener(this);
        button3.setOnClickListener(this);

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);

Answer 1

I have 2 classes, in the first one the list is full, in the 2nd it is empty... the first one is a list of goods, the second one is a shopping cart. How can I fill the basket?

in your case, there is a database anyway, even if you don’t have it yet, most likely you need it, so the answer comes from the fact that you have a database.
describe the ContentProvider use CursorLoader
+ SimpleCursorAdapter
in the products when you click the add to cart button, the product is added to the cart
.... that's all
baskets, moreover, if the price of a product changes, it will change in the basket and in general many other goodies that come out of the box
