Modify keyboard hiding method

Question

There is a method that hides the keyboard

private fun hideKeyboard() { val imm = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager imm?.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS) }

It works, but toggleSoftInput() always works when you click on an element. It hides, it shows the keyboard, and I only need to hide. How can I modify the method? So I understand how it is using iBinder'a ?

Try this method:

 private fun hideKeyboard(View view) { val imm = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager imm?.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS, null) }

The hideSoftInputFromWindow() method can accept 3 parameters as input

IBinder windowToken - The marker of the window from which the request is made. Returned by the view.getWindowToken() method. more about iBinder ...
int flags - Additional working flags. more about flags (section Constants) ...
ResultReceiver resultReceiver - Similarity BroadcastReceiver . If not null , then it will be invoked by the IME when it processes your request to tell you that it has been processed. resultCode you get may be equal to one of these RESULT_UNCHANGED_SHOWN , RESULT_UNCHANGED_HIDDEN , RESULT_SHOWN or RESULT_HIDDEN . more about ResultReceiver ...

there are three parameters '(IBinder windowToken, int flags, ResultReceiver resultReceiver)'
@Morozov in the java implementation, this method can have 2 parameters, namely: (IBinder windowToken, int flags) , since it took the example of java, it turned out to be such an inaccuracy.
@zTrap 0 emphasizes - the integer literal doesn t conform to the expected IBinder!
@Inkognito try passing to the View method that was clicked.
And in the method instead of 0, substitute view.getWindowToken()
@zTrap Yes, I did, just compile for a long time), but why do I need getWindowToken and how does it affect the view?
