利用kotlin的拓展函數(shù)和拓展屬性輕而易舉實(shí)現(xiàn)點(diǎn)擊事件防重復(fù)：
新建一個(gè)kt文件，復(fù)制以下代碼：

inline fun <T : View> T.singleClick(time: Long = 800, crossinline block: (T) -> Unit) {
    setOnClickListener {
        val currentTimeMillis = System.currentTimeMillis()
        if (currentTimeMillis - lastClickTime > time || this is Checkable) {
            lastClickTime = currentTimeMillis
            block(this)
        }
    }
}
//兼容點(diǎn)擊事件設(shè)置為this的情況
fun <T : View> T.singleClick(onClickListener: View.OnClickListener, time: Long = 800) {
    setOnClickListener {
        val currentTimeMillis = System.currentTimeMillis()
        if (currentTimeMillis - lastClickTime > time || this is Checkable) {
            lastClickTime = currentTimeMillis
            onClickListener.onClick(this)
        }
    }
}

var <T : View> T.lastClickTime: Long
    set(value) = setTag(1766613352, value)
    get() = getTag(1766613352) as? Long ?: 0

使用方法：

tvTest.singleClick(1500) {
            Log.e("singClick",System.currentTimeMillis().toString())
        }
//括號(hào)內(nèi)為間隔時(shí)間，可以忽略，默認(rèn)800
//或者
tvTest.singleClick {
            Log.e("singClick",System.currentTimeMillis().toString())
        }
