在带有Kotlin的android中，3个手指长按

import android.content.Context
import android.view.GestureDetector
import android.view.MotionEvent
import android.view.View

class ThreeFingerLongPressDetector(context: Context) : View.OnTouchListener {

    private val gestureDetector: GestureDetector

    init {
        gestureDetector = GestureDetector(context, GestureListener())
    }

    override fun onTouch(view: View, motionEvent: MotionEvent): Boolean {
        return gestureDetector.onTouchEvent(motionEvent)
    }

    private inner class GestureListener : GestureDetector.SimpleOnGestureListener() {

        override fun onDown(e: MotionEvent): Boolean {
            return true
        }

        override fun onLongPress(e: MotionEvent) {
            // 处理3个手指长按操作
            if (e.pointerCount == 3) {
                // 执行相应的操作
            }
        }
    }
}

val myView = findViewById<View>(R.id.my_view)
myView.setOnTouchListener(ThreeFingerLongPressDetector(this))
