如何在android活动中使用多重继承？

public class BaseActivity extends AppCompatActivity {
    // 基础活动类
    // 包含一些共享的功能和属性
}

public interface AdditionalFunctionality {
    // 定义另一个接口，包含其他功能
    void additionalFunction();
}

public class MainActivity extends BaseActivity implements AdditionalFunctionality {
    private AdditionalFunctionality additionalFunctionality;

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

        // 实例化 AdditionalFunctionality
        additionalFunctionality = new AdditionalFunctionalityImpl();

        // 调用 AdditionalFunctionality 中的方法
        additionalFunctionality.additionalFunction();
    }

    @Override
    public void additionalFunction() {
        // 实现 AdditionalFunctionality 接口中的方法
    }
}

public class AdditionalFunctionalityImpl implements AdditionalFunctionality {
    @Override
    public void additionalFunction() {
        // 具体的功能实现
    }
}
