Hide soft keyboard when a button is pressed

[voghDev]

Implement a test that could be like "should hide soft keyboard when search button is pressed"

It would be desirable to bring it to perfect red, then green, for every screen

Use this extension function

fun Context.hideSoftKeyboard(v: View) {
    val imm: InputMethodManager? = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm?.hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS)
}
