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;
    }
}

在kotlin

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

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

如果你在onClick()中进行计算密集型工作，则禁用按钮或设置不可点击是不够的，因为单击事件可以在禁用按钮之前排队。我写了一个实现OnClickListener的抽象基类，你可以重写，通过忽略任何排队点击来修复这个问题:

/** 
 * This class allows a single click and prevents multiple clicks on
 * the same button in rapid succession. Setting unclickable is not enough
 * because click events may still be queued up.
 * 
 * Override onOneClick() to handle single clicks. Call reset() when you want to
 * accept another click.
 */
public abstract class OnOneOffClickListener implements OnClickListener {
    private boolean clickable = true;

    /**
     * Override onOneClick() instead.
     */
    @Override
    public final void onClick(View v) {
        if (clickable) {
            clickable = false;
            onOneClick(v);
            //reset(); // uncomment this line to reset automatically
        }
    }

    /**
     * Override this function to handle clicks.
     * reset() must be called after each click for this function to be called
     * again.
     * @param v
     */
    public abstract void onOneClick(View v);

    /**
     * Allows another click.
     */
    public void reset() {
        clickable = true;
    }
}

用法与OnClickListener相同，但重写OnOneClick()代替:

OnOneOffClickListener clickListener = new OnOneOffClickListener() {
    @Override
    public void onOneClick(View v) {

        // Do stuff

        this.reset(); // or you can reset somewhere else with clickListener.reset();
    }
};
myButton.setOnClickListener(clickListener);

结合Gustavo的答案，我已经在Kotlin中实现了看起来非常干净的扩展:

fun View.setOnSingleClickListener(l: () -> Unit) {
  setOnClickListener { view ->
    l.invoke(view)
      isEnabled = false
      postDelayed({
        isEnabled = true
      }, 600)
  }
}

这是你如何设置这个点击监听器:

yourView.setOnSingleClickListener {
  // Insert your code here
}

这是我的解决方案:

if (waitDouble) {
    waitDouble = false;
    Thread thread = new Thread() {
        @Override
        public void run() {
            try {
                sleep(300);
                if (waitDouble == false) {
                    waitDouble = true;
                    singleClick();  //singleClick
                }
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    };
    thread.start();
} else {//DoubleClick
    DoubleClick();
    waitDouble = true;
}

或者另一种解决方案:

public class NoDoubleClickUtils {
    private static long lastClickTime;
    private final static int SPACE_TIME = 500;

    public static void initLastClickTime() {
        lastClickTime = 0;
    }

    public synchronized static boolean isDoubleClick() {
        long currentTime = System.currentTimeMillis();
        boolean isClick2;
        if (currentTime - lastClickTime > SPACE_TIME) {
            isClick2 = false;
        } else {
            isClick2 = true;
        }
        lastClickTime = currentTime;
        return isClick2;
    }
}
