我需要与片段一起工作，只是放一个标志来控制点击:我只想要第一个，其他的不能访问监听器

private boolean flag = true;

...

@Override
public void onClick(View view) {

    ...

    if (flag) {

        ...

        listener.onFragmentInteraction(Constants.MY_FRAGMENT, bundle);
        flag = false;
    }

    ...

}

希望对大家有用，有不正确的地方请指正

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;

这个解决方案(Kotlin)对我很有效:

abstract class SingleClickListener : View.OnClickListener {
    private val MIN_CLICK_INTERVAL: Long = 1000
    private var mLastClickTime: Long = 0

    abstract fun onSingleClick(v: View?)

    override fun onClick(v: View?) {
        if (mLastClickTime <= 0) {
            mLastClickTime = SystemClock.uptimeMillis()
            onSingleClick(v)
            return
        }

        if (SystemClock.uptimeMillis() - mLastClickTime <= MIN_CLICK_INTERVAL) {
            return
        }

        mLastClickTime = SystemClock.uptimeMillis()

        onSingleClick(v)
    }
}

用法:

someView.setOnClickListener(object : SingleClickListener() {
    override fun onSingleClick(v: View?) {
        v?.also { klik(it) }
    }
})

或者也可以创建扩展函数，在视图上轻松添加ClickListener:

fun View.click(klik: (View) -> Unit) {
    this.setOnClickListener(object : SingleClickListener() {
        override fun onSingleClick(v: View?) {
            v?.also { klik(it) }
        }
    })
}

// Usage
class XPerimentActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_xperiment_layout)

        submit_button.click {
           // do your magic
        }
    }
}

如果你在onClick()中进行计算密集型工作，则禁用按钮或设置不可点击是不够的，因为单击事件可以在禁用按钮之前排队。我写了一个实现OnClickListener的抽象基类，你可以重写，通过忽略任何排队点击来修复这个问题:

/** 
 * This class allows a single click and prevents multiple clicks on
 * the same button in rapid succession. Setting unclickable is not enough
 * because click events may still be queued up.
 * 
 * Override onOneClick() to handle single clicks. Call reset() when you want to
 * accept another click.
 */
public abstract class OnOneOffClickListener implements OnClickListener {
    private boolean clickable = true;

    /**
     * Override onOneClick() instead.
     */
    @Override
    public final void onClick(View v) {
        if (clickable) {
            clickable = false;
            onOneClick(v);
            //reset(); // uncomment this line to reset automatically
        }
    }

    /**
     * Override this function to handle clicks.
     * reset() must be called after each click for this function to be called
     * again.
     * @param v
     */
    public abstract void onOneClick(View v);

    /**
     * Allows another click.
     */
    public void reset() {
        clickable = true;
    }
}

用法与OnClickListener相同，但重写OnOneClick()代替:

OnOneOffClickListener clickListener = new OnOneOffClickListener() {
    @Override
    public void onOneClick(View v) {

        // Do stuff

        this.reset(); // or you can reset somewhere else with clickListener.reset();
    }
};
myButton.setOnClickListener(clickListener);

您也可以使用jake Wharton的rx绑定来实现这一点。下面是一个连续点击之间间隔2秒的例子:

RxView.clicks(btnSave)
                .throttleFirst(2000, TimeUnit.MILLISECONDS, AndroidSchedulers.mainThread())
                .subscribe(new Consumer<Object>() {
                    @Override
                    public void accept( Object v) throws Exception {
//handle onclick event here
                });

//注意:忽略对象v在这种情况下，我认为总是。

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()}"
                   ... />
