通用解决方案

@Override
        public void onClick(View v) {
            tempDisableButton(v);
            //all the buttons view..
        }

public void tempDisableButton(View viewBtn) {
        final View button = viewBtn;

        button.setEnabled(false);
        button.postDelayed(new Runnable() {
            @Override
            public void run() {
                button.setEnabled(true);
            }
        }, 3000);
    }

对我来说,只有记住时间戳并检查它(距离上次点击超过1秒)才有帮助。

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;

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!");
            }
     };

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() }

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);
}
