按下按钮5秒钟后执行操作

Question

我正在尝试在if user presses button for 5 seconds, then it should perform some action的android系统中实现情景定位。

通常，用户按下特定按钮5秒钟以上，然后应在此之后触发侦听器。

非常感谢您的回答。

我找到了解决此问题的方法

private var job: Job? = null
private var iSBeingClicked = false

fun initBtn() {
btnPlusMinus.setOnTouchListener { view, event ->
            if(event.action == MotionEvent.ACTION_DOWN) {
                isBeingClicked = true
                job?.cancel()
                job = lifecycleScope.launch {
                    delay(5000)
                    if(isBeingClicked) {
                        // do whatever your action
                        isBeingClicked = false
                    }
                }
            }

            if((event.action == MotionEvent.ACTION_UP)) {
                isBeingClicked = false
                job?.cancel()
                // if btn pressed out in less than 5 secs
                // it should perform traditional click 
                btnPlusMinus.performClick()
            }

            true
        }
}
