I found none of these suggestions works if the onClick method doesn't return immediately. The touch event is queued by Android and the next onClick is called only after the first one is finished. (Since this is done on the one UI thread this is really normal.) I needed to use the time when the the onClick function is finished + one boolean variable to mark whether the given onClick is running. Both these marker attributes are static to avoid any onClickListener to run at the same time. (If user clicks on another button) You can simple replace your OnClickListener to this class and instead of implementing the onClick method you need to implement the abstract oneClick() method.

    abstract public class OneClickListener implements OnClickListener {

    private static boolean started = false;
    private static long lastClickEndTime = 0;

    /* (non-Javadoc)
     * @see android.view.View.OnClickListener#onClick(android.view.View)
     */
    @Override
    final public void onClick(final View v) {
        if(started || SystemClock.elapsedRealtime()-lastClickEndTime <1000 ){
            Log.d(OneClickListener.class.toString(), "Rejected double click, " + new Date().toString() );
            return; 
        }
        Log.d(OneClickListener.class.toString(), "One click, start: " + new Date().toString() );
        try{
            started = true;
            oneClick(v);
        }finally{
            started = false;
            lastClickEndTime = SystemClock.elapsedRealtime();
            Log.d(OneClickListener.class.toString(), "One click, end: " + new Date().toString() );
        }
    }

    abstract protected void oneClick(View v);
}

下面的代码将防止用户点击多次在几分之一秒内，只允许3秒后。

private long lastClickTime = 0;

View.OnClickListener buttonHandler = new View.OnClickListener() {
    public void onClick(View v) {
        // preventing double, using threshold of 3000 ms
        if (SystemClock.elapsedRealtime() - lastClickTime < 3000){
            return;
        }

        lastClickTime = SystemClock.elapsedRealtime();
    }
}

我的解决方案是

package com.shuai.view;

import android.os.SystemClock;
import android.view.View;

/**
 * 处理快速在某个控件上双击2次(或多次)会导致onClick被触发2次(或多次)的问题
 * 通过判断2次click事件的时间间隔进行过滤
 * 
 * 子类通过实现{@link #onSingleClick}响应click事件
 */
public abstract class OnSingleClickListener implements View.OnClickListener {
    /**
     * 最短click事件的时间间隔
     */
    private static final long MIN_CLICK_INTERVAL=600;
    /**
     * 上次click的时间
     */
    private long mLastClickTime;

    /**
     * click响应函数
     * @param v The view that was clicked.
     */
    public abstract void onSingleClick(View v);

    @Override
    public final void onClick(View v) {
        long currentClickTime=SystemClock.uptimeMillis();
        long elapsedTime=currentClickTime-mLastClickTime;
        //有可能2次连击，也有可能3连击，保证mLastClickTime记录的总是上次click的时间
        mLastClickTime=currentClickTime;

        if(elapsedTime<=MIN_CLICK_INTERVAL)
            return;

        onSingleClick(v);        
    }

}

用法类似于OnClickListener，但重写onSingleClick()代替:

mTextView.setOnClickListener(new OnSingleClickListener() {
            @Override
            public void onSingleClick(View v) {
                if (DEBUG)
                    Log.i("TAG", "onclick！");
            }
     };

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;
    }

}

扩展的Kotlin方法:

fun View.setOneTimeClickListener(delayMillis: Long = 1000, block: () -> Unit) {
    setOnClickListener {
        this.isEnabled = false
        block()
        postDelayed({ isEnabled = true }, delayMillis)
    }

在代码中的用法:

someView.setOneTimeClickListener { someFun() }

delayMillis参数可用于设置按钮将被禁用的时间。

someView.setOneTimeClickListener(500) { someFun() }

防止点击乘法btns

使用:

private val disposables = CompositeDisposable()
private val clickInteractor = ClickInteractor(disposables)
...
button1.setOnClickListener{
     clickInteractor.click {
          Toast.makeText(context, "Btn1", Toast.LENGTH_LONG).show()
     }
}
button2.setOnClickListener{
     clickInteractor.click {
          Toast.makeText(context, "Btn2", Toast.LENGTH_LONG).show()
     }
}

ClickInteractor.kt:

class ClickInteractor constructor(disposables: CompositeDisposable) {
    private val performPublish = PublishSubject.create<ClickInteractorCallback>()

    init {
        performPublish
            .subscribeOn(Schedulers.io())
            .observeOn(Schedulers.io())
            .throttleFirst(1, TimeUnit.SECONDS, Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .doOnNext { callback ->
                callback.invoke()
            }
            .retry()
            .execute(disposables)
    }

    fun click(callback: ClickInteractorCallback) {
        performPublish.onNext(callback)
    }
}

typealias ClickInteractorCallback = () -> Unit
