How to hide Soft Keyboard when activity starts

Question

I have an Edittext with android:windowSoftInputMode="stateVisible" in Manifest. Now the keyboard will be shown when I start the activity. How to hide it? I cannot use android:windowSoftInputMode="stateHidden because when keyboard is visible then minimize the app and resume it the keyboard should be visible. I tried with

InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

but it did not work.

If you don't want to use xml, make a Kotlin Extension to hide keyboard

// In onResume, call this
myView.hideKeyboard()

fun View.hideKeyboard() {
    val inputMethodManager = context.getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager
    inputMethodManager.hideSoftInputFromWindow(windowToken, 0)
}

Alternatives based on use case:

fun Fragment.hideKeyboard() {
    view?.let { activity?.hideKeyboard(it) }
}

fun Activity.hideKeyboard() {
    // Calls Context.hideKeyboard
    hideKeyboard(currentFocus ?: View(this))
}

fun Context.hideKeyboard(view: View) {
    view.hideKeyboard()
}

How to show soft keyboard

fun Context.showKeyboard() { // Or View.showKeyboard()
    val inputMethodManager = context.getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager
    inputMethodManager.toggleSoftInput(SHOW_FORCED, HIDE_IMPLICIT_ONLY)
}

Simpler method when simultaneously requesting focus on an edittext

myEdittext.focus()

fun View.focus() {
    requestFocus()
    showKeyboard()
}

Bonus simplification:

Remove requirement for ever using getSystemService: Splitties Library

// Simplifies above solution to just
inputMethodManager.hideSoftInputFromWindow(windowToken, 0)
