Android启动应用时屏蔽RecyclerView滑动，延时后再允许滑动，Kotlin
var bCanScrollVertically = falselifecycleScope.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recyclerviewbCanScrollVertically = trueLog.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.VERTICALrv.layoutManager = layoutManager
