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)。

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);

扩展的Kotlin方法:

fun View.setOneTimeClickListener(delayMillis: Long = 1000, block: () -> Unit) {
    setOnClickListener {
        this.isEnabled = false
        block()
        postDelayed({ isEnabled = true }, delayMillis)
    }

在代码中的用法:

someView.setOneTimeClickListener { someFun() }

delayMillis参数可用于设置按钮将被禁用的时间。

someView.setOneTimeClickListener(500) { someFun() }

如果按钮做的唯一一件事是启动一个新活动，这个问题可以通过“singleTop”活动启动模式和在意图上设置FLAG_ACTIVITY_CLEAR_TOP来解决。这种方法不适用于复杂活动的层次结构，但适用于简单的树状应用程序结构。

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()
}

防止点击乘法btns

使用:

private val disposables = CompositeDisposable()
private val clickInteractor = ClickInteractor(disposables)
...
button1.setOnClickListener{
     clickInteractor.click {
          Toast.makeText(context, "Btn1", Toast.LENGTH_LONG).show()
     }
}
button2.setOnClickListener{
     clickInteractor.click {
          Toast.makeText(context, "Btn2", Toast.LENGTH_LONG).show()
     }
}

ClickInteractor.kt:

class ClickInteractor constructor(disposables: CompositeDisposable) {
    private val performPublish = PublishSubject.create<ClickInteractorCallback>()

    init {
        performPublish
            .subscribeOn(Schedulers.io())
            .observeOn(Schedulers.io())
            .throttleFirst(1, TimeUnit.SECONDS, Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .doOnNext { callback ->
                callback.invoke()
            }
            .retry()
            .execute(disposables)
    }

    fun click(callback: ClickInteractorCallback) {
        performPublish.onNext(callback)
    }
}

typealias ClickInteractorCallback = () -> Unit
