Answer 1

I had extension for fragment, but didn't work with dialog fragment. This extension works for both (not tested much tho)

/**
 * If no window token is found, keyboard is checked using reflection to know if keyboard visibility toggle is needed
 *
 * @param useReflection - whether to use reflection in case of no window token or not
 */
fun Fragment.hideKeyboard(context: Context = App.instance, useReflection: Boolean = true) {
    val windowToken = view?.rootView?.windowToken
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    windowToken?.let {
        imm.hideSoftInputFromWindow(windowToken, 0)
    } ?: run {
        if (useReflection) {
            try {
                if (getKeyboardHeight(imm) > 0) {
                    imm.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS)
                }
            } catch (exception: Exception) {
                Timber.e(exception)
            }
        }
    }
}

fun getKeyboardHeight(imm: InputMethodManager): Int = InputMethodManager::class.java.getMethod("getInputMethodWindowVisibleHeight").invoke(imm) as Int

Edit: toggle opened keyboard if it was closed before, I use reflection to get keyboard's height, which is not best solution, but works

Kotil Extension function for DialogFragment hide keyboard

 use : hideKeyboard(view)

fun DialogFragment.hideKeyboard(view: View) {
    val imm =view.context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(view.windowToken, 0)
}

I found only one fully working approach if you want to show keyboard when dialog is shown and hide keyboard when dialog is dismissed

<style name="InputDialog" parent="ThemeOverlay.AppCompat.Dialog.Alert">
    <item name="android:windowSoftInputMode">stateAlwaysVisible</item>
</style>

And then you should use the theme above inside your DialogFragment

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setStyle(STYLE_NORMAL, R.style.InputDialog)
}

Hiding keyboard in a View inside DialogFragment:

public static void hideKeyboardInAndroidFragment(View view){
        final InputMethodManager imm = (InputMethodManager) view.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

Answer 5

for hide soft keyboard, you can use this method:

public void hideSoftKeyboard() {
        try {
            View windowToken = getDialog().getWindow().getDecorView().getRootView();
            InputMethodManager imm = (InputMethodManager) getDialog().getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow( windowToken.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
        } catch (Exception ex) {
            Log.e(ex);
        }
    }

Hide it in DialogFragment onDestroyView() method:

 View view = getActivity().getCurrentFocus();
        if (view == null) view = new View(activity);
        InputMethodManager imm = (InputMethodManager)     getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
        if (imm == null) return;
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);

maybe work.
