Edittext is gaining focus and showing the keyboard after AlertDialog dismissed

Question

I have an EditText in a fragment and in an AlertDialog. I'm using the EditText and then click the done button. But whenever I dismiss the AlertDialog the Edittext is gaining focus and showing the keyboard. I don't want to show the keyboard after AlerDialog closes. How can I resolve this?

I used val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager imm.hideSoftInputFromWindow(view.windowToken, 0) after dismissing the AlertDialog, but it didn't work.

Answer 1

create Extensions.kt

fun Activity.hideKeyboard(event: MotionEvent) {
    if (event.action == MotionEvent.ACTION_DOWN) {
        val view = currentFocus
        if (view != null) {
            view.clearFocus()
            val inputMethodManager =
                getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
            inputMethodManager.hideSoftInputFromWindow(
                view.windowToken,
                InputMethodManager.HIDE_NOT_ALWAYS
            )
        }
    }
}

activity you will use

override fun dispatchTouchEvent(event: MotionEvent): Boolean {
        hideKeyboard(event)
        return super.dispatchTouchEvent(event)
    }

Extensions. create kt this way you can use it in any activity you want. Extensions. Delete kt except libraries and this write code

Answer 2

Try this:

fun showKeyboard(view: View) = ViewCompat.getWindowInsetsController(view)?.show(WindowInsetsCompat.Type.ime())

showKeyboard(binding.root)    //<- the root View of your dialog
