java - 删除条件语句

Question

我想知道如何删除条件语句并用方法替换它。对于没有监听器的代码，我可以做到。但是这个有监听器事件（arg0），这让我很困惑。仅供参考，这段代码在主类中，我想把这些代码从主类中删除。

感谢您的帮助！！

@Override
public void onMotionSensingEvent( MotionSensingEvent arg0) {

    double gradient = 1.38;
    double speed;

    float testpitch = 0;
    testpitch = arg0.getOrientation().getPitch();

    float testroll = 0;
    testroll = arg0.getOrientation().getRoll();

    if (testroll > 16 && flyingControl)
    {
        speed = gradient*testroll-22.1;
        System.out.println("kanan = " + speed);
        ardrone.goRight(speed);
    }
    else if (testroll < (-24) && flyingControl)
    {
        speed = gradient*testroll*-1 - 22.1;
        System.out.println("kiri = " + speed);
        ardrone.goLeft(speed);
    }
    else if (testpitch < (-20) && flyingControl)
    {
        System.out.println("go up");
        ardrone.up();
    }
    else if (testpitch > 20 && flyingControl)
    {
        System.out.println("go down");
        ardrone.down();
    }
    else
    {
        ardrone.stop();
    }

}
