Android – Close/hide the Android Soft Keyboard with Kotlin

androidandroid-softkeyboardkotlin

I'm trying to write a simple Android app in Kotlin. I have an EditText and a Button in my layout. After writing in the edit field and clicking on the Button, I want to hide the virtual keyboard.

There is a popular question Close/hide the Android Soft Keyboard about doing it in Java, but as far as I understand, there should be an alternative version for Kotlin. How should I do it?

Best Solution

Use the following utility functions within your Activities, Fragments to hide the soft keyboard.

(*)Update for the latest Kotlin version

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

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

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

This will close the keyboard regardless of your code either in dialog fragment and/or activity etc.

Usage in Activity/Fragment:

hideKeyboard()

Android – How to close/hide the Android soft keyboard programmatically

You can force Android to hide the virtual keyboard using the InputMethodManager, calling hideSoftInputFromWindow, passing in the token of the window containing your focused view.

// Check if no view has focus:
View view = this.getCurrentFocus();
if (view != null) {  
    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

This will force the keyboard to be hidden in all situations. In some cases, you will want to pass in InputMethodManager.HIDE_IMPLICIT_ONLY as the second parameter to ensure you only hide the keyboard when the user didn't explicitly force it to appear (by holding down the menu).

Note: If you want to do this in Kotlin, use: context?.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager

Kotlin Syntax

// Only runs if there is a view that is currently focused
this.currentFocus?.let { view ->
    val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager
    imm?.hideSoftInputFromWindow(view.windowToken, 0)
}

Android – How to make an Android EditView ‘Done’ button and hide the keyboard when clicked

First you need to set the android:imeOptions attribute equal to actionDone for your target EditText as seen below. That will change your ‘RETURN’ button in your EditText’s soft keyboard to a ‘DONE’ button.

<EditText 
    android:id="@+id/edittext_done"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="Enter some text"
    android:imeOptions="actionDone"
    android:singleLine="true"
    />
