加上Jim的回答，代码可以变得更简洁:

fun View.setOnSingleClick(onClick: () -> Unit) {
    var lastClickTime = 0L
    setOnClickListener {
        if (currentTimeMillis() > lastClickTime + 750) onClick()
        lastClickTime = currentTimeMillis()
    } 
}

用法:

aView.setOnSingleClick {  }

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;
    }
}

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;
}

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。

在点击的时候保存最后一次点击的时间可以避免这个问题。

i.e.

private long mLastClickTime = 0;

...

// inside onCreate or so:

findViewById(R.id.button).setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        // mis-clicking prevention, using threshold of 1000 ms
        if (SystemClock.elapsedRealtime() - mLastClickTime < 1000){
            return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();

        // do your magic here
    }
}

在kotlin

button.setOnClickListener { 
    it?.apply { isEnabled = false; postDelayed({ isEnabled = true }, 400) } //400 ms
    //do your work
}
