下面是一个OnClickListener代理，它可以根据qezt的答案阻止连续的单击。

import android.os.SystemClock;
import android.view.View;

public class MultiClickGuard implements View.OnClickListener {    

    private long mLastClickTime;

    private final int mThresholdMillis;
    private final View.OnClickListener mListener;

    public MultiClickGuard(View.OnClickListener listener, int thresholdMillis) {
        if (listener == null) {
            throw new NullPointerException("Null OnClickListener");
        }
        if (thresholdMillis < 0) {
            throw new IllegalArgumentException("Negative click threshold: " + thresholdMillis);
        }

        mListener = listener;
        mThresholdMillis = thresholdMillis;
    }

    @Override
    public void onClick(View v) {
        // Using a time threshold to prevent successive clicks.
        if (SystemClock.elapsedRealtime() - mLastClickTime < mThresholdMillis) {
            return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();

        // Forward the click event to the *real* listener.
        mListener.onClick(v);
    }
}

用法示例

button.setOnClickListener(new MultiClickGuard(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // do something
    }
}, 1000));

button.setOnClickListener(new MultiClickGuard(v -> {...}, 1000));
button.setOnClickListener(new MultiClickGuard(v -> doSomething(), 1000));

在试图阻止启动一个活动的多个实例的情况下，考虑指定启动模式:理解任务和返回堆栈，这是可靠的方式。

如果您试图阻止打开一个对话框片段的多个实例，您可以检查片段管理器是否已经包含了对话框，例如getSupportFragmentManager(). findfragmentbytag (tag)。

点击保护工作与黄油刀

ClickGuard.guard(mPlayButton);

我需要与片段一起工作，只是放一个标志来控制点击:我只想要第一个，其他的不能访问监听器

private boolean flag = true;

...

@Override
public void onClick(View view) {

    ...

    if (flag) {

        ...

        listener.onFragmentInteraction(Constants.MY_FRAGMENT, bundle);
        flag = false;
    }

    ...

}

希望对大家有用，有不正确的地方请指正

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);
}

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).
