Android启动应用时屏蔽RecyclerView滑动，延时后再允许滑动，Kotlin

Kotlin 复制代码

        var bCanScrollVertically = false

        lifecycleScope.launch(Dispatchers.Default) {
            repeatOnLifecycle(Lifecycle.State.CREATED) {
                Log.d(TAG, "Lifecycle.State.CREATED")
                delay(8000) //延迟一定时间才允许用户滑动recyclerview

                bCanScrollVertically = true
                Log.d(TAG, "repeatOnLifecycle delay 结束")
            }
        }

        val layoutManager = object : LinearLayoutManager(this) {
            override fun canScrollVertically(): Boolean {
                return bCanScrollVertically
            }
        }

        val gestureDetector = GestureDetector(this, object : GestureDetector.SimpleOnGestureListener() {
            override fun onFling(e1: MotionEvent?, e2: MotionEvent, velocityX: Float, velocityY: Float): Boolean {
                if (!bCanScrollVertically) {
                    Toast.makeText(applicationContext, "请耐心等待几秒再滑动", Toast.LENGTH_SHORT).show()
                }

                return super.onFling(e1, e2, velocityX, velocityY)
            }
        })

        rv.setOnTouchListener(object : View.OnTouchListener {
            override fun onTouch(v: View?, event: MotionEvent?): Boolean {
                if (!bCanScrollVertically) {
                    gestureDetector.onTouchEvent(event!!)
                }
                return false
            }
        })

        layoutManager.orientation = LinearLayoutManager.VERTICAL
