val bm = bluetoothManager
val am = audioManager

• startActivity拓展

registerReceiver(
    WifiManager.WIFI_STATE_CHANGED_ACTION,
    WifiManager.SCAN_RESULTS_AVAILABLE_ACTION
) {
    it ?: return@registerReceiver
    val rssi = it.getIntExtra(WifiManager.EXTRA_NEW_RSSI, -1000)
    toast("$rssi")
}
startActivity<XXActivity> {
    addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK)
    withArgs {
        "key" to "value"

    text = SpannableUtils.create {
        text("已同意").foregroundColor(Color.DKGRAY)
        text("隐私政策").underline().click { toast("隐私政策") }
        text("和").absoluteSize(20.sp)
        text("用户协议").underline().click { toast("用户协议") }
    }
    movementMethod = LinkMovementMethod.getInstance()
}

• 点击事件消抖

• 双击退出

• 验证码倒计时

val time = AtomicInteger()
btn.doOnClickAntiShake(1000, {
    toast("YOU CLICK TOO FAST")
}) {
    toast("REAL CLICK")
    textView2.text = "TIME " + time.getAndIncrement()
}

btn.doOnClickMultiple(onClickProgress = {
    toast("CLICK AGAIN TO EXIT")
}) {
    exitProcess(0)
}
btn.doOnClickCountdown(60, {
    textView3.text = if (it > 0) "$it S" else "SEND"
}, {
    toast("IN COOLING TIME")
