Kotlin: How to override a class, then pass it to a function as an anonymous function argument

```kotlin

val commonDestureDetector = GestureDetector(this, object : GestureDetector.OnGestureListener {
    // 1. 用户轻触触摸屏
    override fun onDown(e: MotionEvent): Boolean {
        Log.i("MyGesture", "onDown")
        return false
    }

    // 2. 用户轻触触摸屏，尚未松开或拖动
    // 与onDown()的区别：无松开 / 拖动
    // 即：当用户点击的时，onDown（）就会执行，在按下的瞬间没有松开 / 拖动时onShowPress就会执行
    override fun onShowPress(e: MotionEvent) {
        Log.i("MyGesture", "onShowPress")
    }

    // 3. 用户长按触摸屏
    override fun onLongPress(e: MotionEvent) {
        Log.i("MyGesture", "onLongPress")
    }

    // 4. 用户轻击屏幕后抬起
    override fun onSingleTapUp(e: MotionEvent): Boolean {
        Log.i("MyGesture", "onSingleTapUp")
        return true
    }

    // 5. 用户按下触摸屏 & 拖动
    override fun onScroll(
        e1: MotionEvent, e2: MotionEvent,
        distanceX: Float, distanceY: Float
    ): Boolean {
        Log.i("MyGesture", "onScroll:")
        return true
    }

    // 6. 用户按下触摸屏、快速移动后松开
    // 参数：
    // e1：第1个ACTION_DOWN MotionEvent
    // e2：最后一个ACTION_MOVE MotionEvent
    // velocityX：X轴上的移动速度，像素/秒
    // velocityY：Y轴上的移动速度，像素/秒
    override fun onFling(
        e1: MotionEvent, e2: MotionEvent, velocityX: Float,
        velocityY: Float
    ): Boolean {
        Log.i("MyGesture", "onFling")
        return true
    }
})

commonDestureDetector.setOnDoubleTapListener(object : GestureDetector.OnDoubleTapListener {
    override fun onSingleTapConfirmed(p0: MotionEvent?): Boolean {
        TODO("Not yet implemented")
    }

    override fun onDoubleTap(p0: MotionEvent?): Boolean {
        TODO("Not yet implemented")
    }

    override fun onDoubleTapEvent(p0: MotionEvent?): Boolean {
        TODO("Not yet implemented")
    }
})

```
