How to hide keybord Kotlin

To hide the keyboard in Kotlin, you can use the InputMethodManager class. Here are the steps to achieve this:

1. Get a reference to the InputMethodManager using the getSystemService() method. This method retrieves the system-level service for managing input methods.

2. Use the hideSoftInputFromWindow() method of the InputMethodManager to hide the keyboard. This method takes two parameters: the IBinder token of the window containing the view that has the keyboard focus, and a flag specifying additional operating options.

3. The IBinder token of the window can be obtained from any view using the getWindowToken() method.

4. The flag can be set to 0 or to any combination of the following constants, depending on the desired behavior: InputMethodManager.HIDE_IMPLICIT_ONLY, InputMethodManager.HIDE_NOT_ALWAYS.

Here's an example of how you can implement these steps in Kotlin:

import android.content.Context
import android.os.IBinder
import android.view.View
import android.view.inputmethod.InputMethodManager

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

In the example above, the hideKeyboard() function takes two parameters: the Context object and the View object that has the keyboard focus. You can call this function whenever you want to hide the keyboard.

Please note that this implementation assumes you have the necessary imports and that you are calling the hideKeyboard() function from an activity or a fragment.
