Android - Hide keyboard on Android 8

I'm having troubles with hiding the keyboard on Android 8.
I used this before and it worked for the older androids:

val view = activity.currentFocus
if (view != null) {
val imm = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(view.windowToken, 0)
}
Android 8 just ignores it and shows the keyboard anyway.
Probably making the input field unfocusable would help, but I really need it to be focusable, so this is not an option.

Instead of `hideSoftInputFromWindow` you can use `toggleSoftInput`.

val imm: InputMethodManager = getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
if (imm.isActive)
imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0)

works for Android 8 on the emulator at least

I had a similar problem and I solved it like this:

class MainActivity : Activity() {

override fun onCreate(savedInstanceState: Bundle?) {
...
window.setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN)

}
}

> This is not the most elegant solution. But in my situation it was acceptable

Use this method I have created

public static void showHideInput(Context context,boolean visibility, View view){

if (view != null) {
InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
if (visibility) imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
else imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}

I had the same issue recently, and worked around it by providing the root view from (in my case) the fragment for the window token instead of the activity's current focus.
<BR><BR>This way, the keyboard is dismissed, and focus in the `EditText` is maintained.

Tested on Pixel 2 XL running `Android 8.1`:

/**
* Hides the Soft Keyboard on demand
*
* @param activity the activity from which to get the IMM
* @param view the view from which to provide a windowToken
*/
fun hideSoftKeyboard(activity: Activity, view: View?) {
val inputMethodManager = activity.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.hideSoftInputFromWindow(view?.windowToken, 0)
}

Hide keyboard inside runnable, with calling post method of your view:

view.post(() -> {
hideKeyboard(view);
}

The @EarlOfEgo 's solution caused some troubles on older Android versions. This is the ideal solution, which works perfectly on all (at least almost) Android versions:

protected fun hideKeyboard() {
val view = activity.currentFocus
if(android.os.Build.VERSION.SDK_INT >= 26) {
val imm: InputMethodManager = context.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
view?.post({
imm.hideSoftInputFromWindow(activity.currentFocus.windowToken, 0)
imm.hideSoftInputFromInputMethod(activity.currentFocus.windowToken, 0)
})
} else {
if (view != null) {
val imm = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(view.windowToken, 0)
imm.hideSoftInputFromInputMethod(view.windowToken, 0)
}
}
}

just try this method to intercept the focus event and hide the softkeyboard:

@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);

if (hasFocus) {
View lFocused = getCurrentFocus();
if (lFocused != null)
lFocused.postDelayed(new Runnable() {
@Override
public void run() {
InputMethodManager lInputManager = (InputMethodManager) pContext.getSystemService(Context.INPUT_METHOD_SERVICE);
lInputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
}
}, 100);//Modified to 100ms to intercept SoftKeyBoard on Android 8 (Oreo) and hide it.
}
}

Here you have two static functions to hide keyboard, depend on your case which one you want to use. I tested on Android Oreo and it works.

object UIHelper {

fun hideSoftKeyboard(activity: Activity?) {
if (activity != null) {
val inputManager = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
if (activity.currentFocus != null && inputManager != null) {
inputManager.hideSoftInputFromWindow(activity.currentFocus!!.windowToken, 0)
inputManager.hideSoftInputFromInputMethod(activity.currentFocus!!.windowToken, 0)
}
}
}

fun hideSoftKeyboard(view: View?) {
if (view != null) {
val inputManager = view!!.getContext().getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
inputManager?.hideSoftInputFromWindow(view!!.getWindowToken(), 0)
}
}

fun showKeyboard(activityContext: Context, editText: EditText) {
editText.requestFocus()
Handler().postDelayed(Runnable {
val inputMethodManager = activityContext.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT)
}, 250)
}
}

Example of use:

1. `UIHelper.hideSoftKeyboard(this)`
2. `UIHelper.hideSoftKeyboard(passwordField)`

To show:

UIHelper.showKeyboard(this, passwordField)
