How to show/hide the Android soft keyboard programmatically?

You can force Android to close or hide the virtual keyboard using the
InputMethodManager calling and passing in the token of
the window containing your focused view.Similarly, you can show the virtual keyboard using the
InputMethodManager calling showSoftInput and
passing your focused view and flag.
// hide keyboard
fun dismissKeyboard(view: View?) {
if (view != null) {
val imm = view.context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(view.windowToken, 0)
}
}
// show keyboard
fun showKeyboard(view: View?) {
if (view == null) return
view.requestFocus()
val imm = view.context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
if (view is EditText) imm.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT)
else imm.toggleSoftInput(
InputMethodManager.SHOW_FORCED,
InputMethodManager.HIDE_IMPLICIT_ONLY
)
}
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).
WindowSoftInputMode
By default, Android will automatically assign the initial focus to the
first
EditText or focusable control in your Activity. It naturally
follows that the InputMethod (typically the soft keyboard) will
respond to the focus event by showing itself. The windowSoftInputMode
attribute in AndroidManifest.xml, when set to stateAlwaysHidden,
instructs the keyboard to ignore this automatically-assigned initial
focus.
<activity android:name=".MainActivity"
android:windowSoftInputMode="stateAlwaysHidden"/>
