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)

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。

在我的情况下，我使用按钮视图，它的点击速度太快了。只需禁用点击，并在几秒钟后再次启用它…

基本上我做了一个包装类，包装你的Views onClickListener。如果您愿意，还可以设置自定义延迟。

public class OnClickRateLimitedDecoratedListener implements View.OnClickListener {

    private final static int CLICK_DELAY_DEFAULT = 300;
    private View.OnClickListener onClickListener;
    private int mClickDelay;


        public OnClickRateLimitedDecoratedListener(View.OnClickListener onClickListener) {
            this(onClickListener, CLICK_DELAY_DEFAULT);
        }

        //customize your own delay
        public OnClickRateLimitedDecoratedListener(View.OnClickListener onClickListener, int delay) {
            this.onClickListener = onClickListener;
            mClickDelay = delay;
        }

        @Override
        public void onClick(final View v) {
            v.setClickable(false);
            onClickListener.onClick(v);

            v.postDelayed(new Runnable() {
                @Override
                public void run() {
                    v.setClickable(true);
                }
            }, mClickDelay);
        }
    }

简单地调用它:

mMyButton.setOnClickListener(new OnClickRateLimitedDecoratedListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                 doSomething();
             }
         }));

或者提供你自己的延迟:

 mMyButton.setOnClickListener(new OnClickRateLimitedDecoratedListener(new View.OnClickListener() {
                     @Override
                     public void onClick(View v) {
                         doSomething();
                     }
                 },1000));

更新:以上方式有点过时，现在RxJava是如此流行。正如其他人所提到的，在android中我们可以使用油门来减慢点击。这里有一个例子:

 RxView.clicks(myButton)
                    .throttleFirst(2000, TimeUnit.MILLISECONDS, AndroidSchedulers.mainThread())
                    .subscribe {
                        Log.d("i got delayed clicked")
                    }
        }

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;
    }
}

对于任何使用数据绑定的用户:

@BindingAdapter("onClickWithDebounce")
fun onClickWithDebounce(view: View, listener: android.view.View.OnClickListener) {
    view.setClickWithDebounce {
        listener.onClick(view)
    }
}

object LastClickTimeSingleton {
    var lastClickTime: Long = 0
}

fun View.setClickWithDebounce(action: () -> Unit) {
    setOnClickListener(object : View.OnClickListener {

        override fun onClick(v: View) {
            if (SystemClock.elapsedRealtime() - LastClickTimeSingleton.lastClickTime < 500L) return
            else action()
            LastClickTimeSingleton.lastClickTime = SystemClock.elapsedRealtime()
        }
    })
}



<androidx.appcompat.widget.AppCompatButton
                    ..
  android:text="@string/signup_signin"
  app:onClickWithDebounce="@{() -> viewModel.onSignUpClicked()}"
                   ... />
