更换德precated GestureDetector构造

问题描述

所以下面我有一个GestureDetector，但整个事情显示德precated构造在Eclipse ..

So below I've got a GestureDetector, but the whole thing shows "Deprecated Constructor" in Eclipse..

我用它来检测和飞灰湮灭它的伟大工程，但我无法找到一个并行构造。整个事情是去precated。要什么我切换到？

I'm using it to detect flings and it works great but I'm unable to find a parallel constructor. The whole thing is deprecated. To what do I switch over to?

不管怎么说，这里的code：

Anyways, here's the code:

mGestureDetector = new GestureDetector(
            new GestureDetector.SimpleOnGestureListener() {
                @Override
                public boolean onDown(MotionEvent e) {
                    return true;
                }

                @Override
                public boolean onFling(MotionEvent e1, MotionEvent e2,
                        float velocityX, float velocityY) {
                    // Roll the ball in the direction of the fling
                    Direction mCommandedRollDirection = Direction.NONE;

                    if (Math.abs(velocityX) > Math.abs(velocityY)) {
                        if (velocityX < 0)
                            mCommandedRollDirection = Direction.LEFT;


                    else
                                mCommandedRollDirection = Direction.RIGHT;
                        } else {
                            if (velocityY < 0)
                                mCommandedRollDirection = Direction.UP;
                            else
                                mCommandedRollDirection = Direction.DOWN;
                        }

                        if (mCommandedRollDirection != Direction.NONE) {
                            mGameEngine.rollBall(mCommandedRollDirection);
                        }

                        return true;
                    }
                });
        mGestureDetector.setIsLongpressEnabled(false);
    }

很显然，我希望同样的功能。
那么什么样的新功能做我要补充（如有）和构造正是我需要使用？

Clearly, I want the same functionality.So what new functions do I have to add (if any) and which constructor exactly do I need to use?

（是的，我知道关于Android开发文档，但就像我说的，我无法找到的新版本what's，它被称为-GestureDetector）

(Yes, I know about the Android dev docs but like I said I'm having trouble finding the newer version of what's-it-called-GestureDetector)

感谢您！

推荐答案

换来这样的：

GestureDetector gd = new GestureDetector(getActivity(), new OnGestureListener() {
   Methods for the listener
}
