val bm = bluetoothManager
val am = audioManager
- 快速监听activity等的destroy事件
- 快速toast工具
doOnDestroy {

-
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"
}
}

UriUtils.fromAsset("a/b.txt")
- 快速创建 SpannableString
with(findViewById<TextView>(R.id.text)) {
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")

toast("SEND CODE")
}
btn.configLayoutParams<LinearLayout.LayoutParams> {
