1. Kotlin 扩展函数实现防抖(Kotlin)
1.1创建ViewExtension.kt文件：
fun <T : View> T.withTrigger(delay: Long = 800): T {triggerDelay = delayreturn this}/**** 点击事件的View扩展* @param block: (T) -> Unit 函数* @return Unit*/fun <T : View> T.click(block: (T) -> Unit) = setOnClickListener {// ClickUtils.applyPressedViewAlpha(this,0.8f)if (clickEnable()) {block(it as T)}}/**** 带延迟过滤的点击事件View扩展* @param delay Long 延迟时间，默认800毫秒* @param block: (T) -> Unit 函数* @return Unit*/fun <T : View> T.clickWithTrigger(time: Long = 800, block: (T) -> Unit) {// 此处是点击后按钮背景透明度变化 可参考blankj开源工具类// ClickUtils.applyPressedViewAlpha(this,0.6f)triggerDelay = timesetOnClickListener {if (clickEnable()) {block(it as T)}}}private var <T : View> T.triggerLastTime: Longget() = if (getTag(1123460103) != null) getTag(1123460103) as Long else 0set(value) {setTag(1123460103, value)}private var <T : View> T.triggerDelay: Longget() = if (getTag(1123461123) != null) getTag(1123461123) as Long else -1set(value) {setTag(1123461123, value)}private fun <T : View> T.clickEnable(): Boolean {var flag = falseval currentClickTime = System.currentTimeMillis()if (currentClickTime - triggerLastTime >= triggerDelay) {flag = true}triggerLastTime = currentClickTimereturn flag}}
1.2 如何调用
只要是继承View的控件 即可实现view.clickWithTrigger调用(仅限kotlin)
// 例：Button mBtn = findViewByid(R.id.btn)mBtn.clickWithTrigger{// 业务逻辑}
2.RxBinding实现防抖(Java)
2.1 添加依赖
implementation "com.jakewharton.rxbinding3:rxbinding:3.0.0"
2.2 如何实现
// 例：RxView.clicks(view).throttleFirst(1000L,TimeUnit.MILLISECONDS) // 1秒内只有第一次点击有效.observeOn(AndroidSchedulers.mainThread()) .subscribe(x -> {// 业务逻辑});
