How to extend two classes in an Activity?

Question

This is the activity so I want to extend the JavaFX Activity class here since we can't extend two classes in java how do I extend the class next to AppCompatActivity.

public class BarchartActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_barchart);
    }
}

Java is single Inheritance, you can only implement Multiple interfaces — AmrDeveloper, Jun 05 '21 at 07:03

Java can only extends from one class, but many interfaces can be implemented
