Android dismiss keyboard

Question

How do I dismiss the keyboard when a button is pressed?

Answer 1

Here's a Kotlin solution (mixing the various answers in thread)

Create an extension function (perhaps in a common ViewHelpers class)

fun Activity.dismissKeyboard() {
    val inputMethodManager = getSystemService( Context.INPUT_METHOD_SERVICE ) as InputMethodManager
    if( inputMethodManager.isAcceptingText )
        inputMethodManager.hideSoftInputFromWindow( this.currentFocus.windowToken, /*flags:*/ 0)
}

Then simply consume using:

// from activity
this.dismissKeyboard()

// from fragment
activity.dismissKeyboard()
