在Java中有一个本地debounce click监听器

view.setOnClickListener(new DebouncedOnClickListener(1000) { //in milisecs
            @Override
            public void onDebouncedClick(View v) {
                //action
            }
        });

在kotlin

button.setOnClickListener { 
    it?.apply { isEnabled = false; postDelayed({ isEnabled = true }, 400) } //400 ms
    //do your work
}

Kotlin创建类SafeClickListener

class SafeClickListener(
        private var defaultInterval: Int = 1000,
        private val onSafeCLick: (View) -> Unit
) : View.OnClickListener {
    private var lastTimeClicked: Long = 0    override fun onClick(v: View) {
        if (SystemClock.elapsedRealtime() - lastTimeClicked < defaultInterval) {
            return
        }
        lastTimeClicked = SystemClock.elapsedRealtime()
        onSafeCLick(v)
    }
}

在baseClass或else中创建一个函数

fun View.setSafeOnClickListener(onSafeClick: (View) -> Unit) {val safeClickListener = SafeClickListener {
        onSafeClick(it)
    }
    setOnClickListener(safeClickListener)
}

并使用按钮点击

btnSubmit.setSafeOnClickListener {
    showSettingsScreen()
}

Setting the button as clickable false upon clicking and true once it is desired to make the button clickable again is the right approach. For instance, consider the following scenario: you are making a service call upon click of a button and once the service is done you want to display a dialog. For this, once the button is clicked you can set setClickable(false) and once the service responds you will do setClicklable(true) through a reference you pass to your custom dialog. When dialog invokes isShowing() you can trigger the listener and setClicklable(true).

setEnabled(false)非常适合我。

我写{setEnabled(true);}，并在第一次点击按钮时将其设为false。

如果按钮做的唯一一件事是启动一个新活动，这个问题可以通过“singleTop”活动启动模式和在意图上设置FLAG_ACTIVITY_CLEAR_TOP来解决。这种方法不适用于复杂活动的层次结构，但适用于简单的树状应用程序结构。
