I solved this problem by simply adding finish();

btnCancelar.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               finish();
                //startActivity(new Intent(getBaseContext(), MainActivity.class));
            }
        });

He automatically went back to where he was, which for now solves my problem

I have an activity, it has a button that I need to take the user to the main activity in the specific menu item

Activity

when you click cancel it needs to go here in the item “cobrar”

MAIN ACTIVITY

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        BottomNavigationView navView = findViewById(R.id.nav_view);
        // Passing each menu ID as a set of Ids because each
        // menu should be considered as top level destinations.
        AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
                R.id.navigation_home, R.id.navigation_dashboard, R.id.navigation_notifications)
                .build();
        NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
        NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
        NavigationUI.setupWithNavController(navView, navController);
    }
}

Click event

btnCancelar.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(getBaseContext(), MainActivity.class));
            }
        });
