使用setEnabled(false)禁用按钮，直到用户可以安全地再次单击它。

我也遇到了类似的问题，我正在显示一些日期选择器和时间选择器，有时它会被点击2次。我用这个方法解决了这个问题:

long TIME = 1 * 1000;
@Override
public void onClick(final View v) {
v.setEnabled(false);
    
    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            v.setEnabled(true);
        }
    }, TIME);
}

你可以根据自己的需要改变时间。

Kotlin扩展，允许简洁的内联代码和变量双击等待时间

fun View.setDoubleClickListener(listener: View.OnClickListener, waitMillis : Long = 1000) {
    var lastClickTime = 0L
    setOnClickListener { view ->
        if (System.currentTimeMillis() > lastClickTime + waitMillis) {
            listener.onClick(view)
            lastClickTime = System.currentTimeMillis()
        }
    }
}

用法:

anyView.setNoDoubleClickListener(View.OnClickListener { v ->
    // do stuff
})

Or

anyView.setNoDoubleClickListener(View.OnClickListener { v ->
    // do stuff
}, 1500)

我用两个类来解决这个问题，一个类似于@jinshiyi11的答案，另一个是基于显式点击，在这里你只能点击一个按钮一次，如果你想要另一次点击，你必须显式地指出它。

/**
 * Listener que sólo permite hacer click una vez, para poder hacer click
 * posteriormente se necesita indicar explicitamente.
 *
 * @author iberck
 */
public abstract class OnExplicitClickListener implements View.OnClickListener {

    // you can perform a click only once time
    private boolean canClick = true;

    @Override
    public synchronized void onClick(View v) {
        if (canClick) {
            canClick = false;
            onOneClick(v);
        }
    }

    public abstract void onOneClick(View v);

    public synchronized void enableClick() {
        canClick = true;
    }

    public synchronized void disableClick() {
        canClick = false;
    }
}

使用示例:

OnExplicitClickListener clickListener = new OnExplicitClickListener() {
    public void onOneClick(View v) {
        Log.d("example", "explicit click");
        ...
        clickListener.enableClick();    
    }
}
button.setOnClickListener(clickListener);

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;
}

Setting the button as clickable false upon clicking and true once it is desired to make the button clickable again is the right approach. For instance, consider the following scenario: you are making a service call upon click of a button and once the service is done you want to display a dialog. For this, once the button is clicked you can set setClickable(false) and once the service responds you will do setClicklable(true) through a reference you pass to your custom dialog. When dialog invokes isShowing() you can trigger the listener and setClicklable(true).
