只有2步，你可以在你的应用程序的任何地方使用它。

步骤1。创建一个单例管理器[避免多次点击]

package com.im.av.mediator;

import android.os.SystemClock;

import java.util.HashMap;

/**
 * Created by ShuHeng on 16/6/1.
 */
public class ClickManager {



    private HashMap<Integer,Long> laskClickTimeMap=new HashMap<Integer,Long>();
    public volatile static ClickManager mInstance =null;

    public static ClickManager getInstance(){
        if (mInstance == null) {
            synchronized(ClickManager.class) {
                if (mInstance == null) {
                    mInstance = new ClickManager();
                }
            }
        }
        return mInstance;
    }
   public boolean isClickable1s(Integer key){
       Long keyLong = laskClickTimeMap.get(key);
       if(keyLong==null){
           laskClickTimeMap.put(key,SystemClock.elapsedRealtime());
           return true;
       }else{
           if (SystemClock.elapsedRealtime() - keyLong.longValue() < 1000){
               return false;
           }else{
               laskClickTimeMap.put(key,new Long(SystemClock.elapsedRealtime()));
               return true;
           }
       }
   }
}  

步骤2。添加一行，避免多次单击。

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    int id = v.getId();
    if (id == R.id.iv_back) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_back))return;
        //do something
    } else if (id == R.id.iv_light) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_light))return;
        //do something
    } else if (id == R.id.iv_camerarotate) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_camerarotate))return;
           //do something
    } else if (id == R.id.btn_delete_last_clip) {
        if(!ClickManager.getInstance().isClickable1s(R.id.btn_delete_last_clip))return;
          //do something

    } else if (id == R.id.iv_ok) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_ok))return;
        //do something
    }
}

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;

The Best and simple solution i found is 
1. to create a boolean and set as false (default) like
private boolean itemClicked = false;

/* for a safer side you can also declare boolean false in onCreate() also. */
and at onclick() method check 
2. if(!itemClicked)
{
itemClicked = true;
// rest of your coding functionality goes here of onClick method.
}
3. last step is to set boolean false in onResume()
@override
onResume()
{
super.onResume(0);
itemClicked = false;
}

我希望这能帮助你，把代码放在你的事件处理程序。

// --------------------------------------------------------------------------------

    boolean hasTag = null != which.getTag( R.id.preventing_double_click_tag );

    if ( hasTag ) {
        // Do not handle again...
        return;
    } else {
        which.setTag( R.id.action, Boolean.TRUE );

        which.postDelayed( new Runnable() {
            @Override
            public void run() {
                which.setTag( R.id.action, null );
                Log.d( "onActin", " The preventing double click tag was removed." );
            }

        }, 2000 );
    }

如果你不想(或不能)使用布尔标志或覆盖onClickListener，你也可以尝试用android:launchMode="singleTop"在AndroidManifest.xml声明你的活动。

它是如何工作的?

如果活动的实例位于堆栈顶部- new activity不会被创建，相反- onNewIntent()将被调用。 活动可以有多个实例 实例可以驻留在不同的任务中 一个任务可以有多个实例

当UI线程阻塞时，单击事件队列。对于按钮单击事件，请尽快将其更改为后台任务，以避免单击事件在彼此后面排队。

在activity类中声明一个volatile boolean或lock:

private volatile boolean saving = false;

创建一个onClickListener按钮，通过保存和启动一个后台任务来完成工作:

saveButton.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View view) {
        if (!saving) {
            saving = true;
            new SaveAsyncTask().execute();
        }
    }
});

创建一个内部的SaveAsyncTask类来在后台完成工作:

class SaveAsyncTask extends AsyncTask {

    @Override
    protected Object doInBackground(Object[] objects) {
        // Do something here, simulate a 3 second task
        SystemClock.sleep(3000);
        saving = false;
        return null;
    }
}
