按住按钮5秒后执行操作

Question

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

一般情况下，用户按下特定按钮的时间为5+秒，之后应触发listener。

如果你能回答我，我会很感激。

我已经找到了解决这个问题的办法。

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
        }
}
