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

我的解决方案是尝试使用一个布尔变量:

public class Blocker {
    private static final int DEFAULT_BLOCK_TIME = 1000;
    private boolean mIsBlockClick;

    /**
     * Block any event occurs in 1000 millisecond to prevent spam action
     * @return false if not in block state, otherwise return true.
     */
    public boolean block(int blockInMillis) {
        if (!mIsBlockClick) {
            mIsBlockClick = true;
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    mIsBlockClick = false;
                }
            }, blockInMillis);
            return false;
        }
        return true;
    }

    public boolean block() {
        return block(DEFAULT_BLOCK_TIME);
    }
}

并使用如下:

view.setOnClickListener(new View.OnClickListener() {
            private Blocker mBlocker = new Blocker();

            @Override
            public void onClick(View v) {
                if (!mBlocker.block(block-Time-In-Millis)) {
                    // do your action   
                }
            }
        });

更新:Kotlin解决方案，使用视图扩展

fun View.safeClick(listener: View.OnClickListener, blockInMillis: Long = 500) {
    var lastClickTime: Long = 0
    this.setOnClickListener {
        if (SystemClock.elapsedRealtime() - lastClickTime < blockInMillis) return@setOnClickListener
        lastClickTime = SystemClock.elapsedRealtime()
        listener.onClick(this)
    }
}

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()
}

具有Kotlin扩展功能:

fun View.onSingleClick(action: (v: View) -> Unit) {
    setOnClickListener(object : View.OnClickListener {
        override fun onClick(v: View) {
            isClickable = false
            action(v)
            postDelayed({ isClickable = true }, 700)
        }
    })
}

用法:

button.onSingleClick { myAction() }

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()}"
                   ... />

这个问题的实际解决方案是使用setEnabled(false)，灰色按钮，和setClickable(false)，使它第二次点击不能接收，我已经测试过了，它似乎是非常有效的。
