在安卓系统中防止双击按钮的最佳方法是什么?


当前回答

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()}"
                   ... />

使用setEnabled(false)禁用按钮,直到用户可以安全地再次单击它。

你可以用Kotlin扩展函数和RxBinding来实现它

   fun View.clickWithDebounce(debounceTime: Long = 600L, action: () -> Unit): Disposable =
        RxView.clicks(this)
                .debounce(debounceTime, TimeUnit.MILLISECONDS)
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe { action() }

or

fun View.clickWithDebounce(debounceTime: Long = 600L, action: () -> Unit) {
    this.setOnClickListener(object : View.OnClickListener {
        private var lastClickTime: Long = 0

        override fun onClick(v: View) {
            if (SystemClock.elapsedRealtime() - lastClickTime < debounceTime) return
            else action()

            lastClickTime = SystemClock.elapsedRealtime()
        }
    })
}

然后就是:

View.clickWithDebounce{ Your code }

我的解决方案(Kotlin):

class OnDebouncedClickListener(private val delayInMilliSeconds: Long, val action: () -> Unit) : View.OnClickListener {
    var enable = true

    override fun onClick(view: View?) {
        if (enable) {
            enable = false
            view?.postDelayed(delayInMilliSeconds) { enable = true }
            action()
        }
    }
}

fun View.setOnDebouncedClickListener(delayInMilliSeconds: Long = 500, action: () -> Unit) {
    val onDebouncedClickListener = OnDebouncedClickListener(delayInMilliSeconds, action)
    setOnClickListener(onDebouncedClickListener)
}

使用:

button.apply {       
            setOnDebouncedClickListener {
                //your action on click
            }
        }

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)

似乎设置你的点击监听器在onResume和空他们在onPause也有技巧。
