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

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;
    }
}

下面是kotlin扩展函数的方式，将工作于所有视图，保持以下函数在您的Utils或任何文件

fun View.preventDoubleClick() {
this.isEnabled = false
this.postDelayed( { this.isEnabled = true }, 1000)
}

下面是如何从片段或活动中使用它

anyIdOfView?.setOnClickListener {
it.preventDoubleClick()
YourAction()
}

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);

试试这个Kotlin扩展函数:

private var lastClickTime = 0L

fun View.click(action: () -> Unit) {
    setOnClickListener {
        if (SystemClock.elapsedRealtime() - lastClickTime < 600L)
            return@setOnClickListener
        lastClickTime = SystemClock.elapsedRealtime()
        action()
    }
}

它还防止在同一时间点击应用程序的各个部分。

如果点击按钮，你正在打开一个新的片段，只需添加android:clickable="true"到正在打开的新片段的根视图。
