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).

具有Kotlin扩展功能:

fun View.onSingleClick(action: (v: View) -> Unit) {
    setOnClickListener(object : View.OnClickListener {
        override fun onClick(v: View) {
            isClickable = false
            action(v)
            postDelayed({ isClickable = true }, 700)
        }
    })
}

用法:

button.onSingleClick { myAction() }

我更喜欢使用信号量块。它是线程安全的，不仅可以用于按钮。

代码示例很简单:

private UtilsSemaphore buttonSemaphore = new UtilsSemaphore();

public void onClick(View view)
{

    boolean isAllowed = buttonSemaphore.lock();

    if(!isAllowed)
    {
        return;
    }

    final View clickedButton = view;

    clickedButton.setEnabled(false);

    /* some code */

    buttonSemaphore.unlock();
    clickedButton.setEnabled(true);
}


public class UtilsSemaphore {

    public int counter = 0;

    public boolean lock()
    {
        int counterValue = ++counter;
        boolean isAllowed = counterValue < 2;

        if(!isAllowed)
        {
            unlock();
        }

        return isAllowed;
    }

    public void unlock()
    {
        --counter;
    }

}

你可以用Kotlin扩展函数和RxBinding来实现它

   fun View.clickWithDebounce(debounceTime: Long = 600L, action: () -> Unit): Disposable =
        RxView.clicks(this)
                .debounce(debounceTime, TimeUnit.MILLISECONDS)
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe { action() }

or

fun View.clickWithDebounce(debounceTime: Long = 600L, action: () -> Unit) {
    this.setOnClickListener(object : View.OnClickListener {
        private var lastClickTime: Long = 0

        override fun onClick(v: View) {
            if (SystemClock.elapsedRealtime() - lastClickTime < debounceTime) return
            else action()

            lastClickTime = SystemClock.elapsedRealtime()
        }
    })
}

然后就是:

View.clickWithDebounce{ Your code }

将Clickable设置为false对第一次双击不起作用，但后续双击将被阻止。这就好像第一次加载点击委托比较慢，第二次点击在第一次完成之前就被捕获了。

        Button button = contentView.FindViewById<Button>(Resource.Id.buttonIssue);
        button.Clickable = false;
        IssueSelectedItems();
        button.Clickable = true;

对于任何使用数据绑定的用户:

@BindingAdapter("onClickWithDebounce")
fun onClickWithDebounce(view: View, listener: android.view.View.OnClickListener) {
    view.setClickWithDebounce {
        listener.onClick(view)
    }
}

object LastClickTimeSingleton {
    var lastClickTime: Long = 0
}

fun View.setClickWithDebounce(action: () -> Unit) {
    setOnClickListener(object : View.OnClickListener {

        override fun onClick(v: View) {
            if (SystemClock.elapsedRealtime() - LastClickTimeSingleton.lastClickTime < 500L) return
            else action()
            LastClickTimeSingleton.lastClickTime = SystemClock.elapsedRealtime()
        }
    })
}



<androidx.appcompat.widget.AppCompatButton
                    ..
  android:text="@string/signup_signin"
  app:onClickWithDebounce="@{() -> viewModel.onSignUpClicked()}"
                   ... />
