Extensions for onKeyListener

[vipulasri]

onKeyListener() extensions will be helpful

Ex: editText.onkey(KeyEvent.ACTION_DOWN) { //do something }

[sourabhv]

Or make it a vararg? Like

editText.onkey(KeyEvent.ACTION_DOWN, KeyEvent.ACTION_UP, /*other keys*/) { //do something }

[dovahkiin98]

something like this?

inline fun View.onKey(vararg events: Int, crossinline listener: (keyCode: Int) -> Unit) {
    setOnKeyListener { v, keyCode, event ->
        if (event.action in events) {
            listener(keyCode)
            true
        }
        else false
    }
}
