How get selected chips text in a chip group

While using chip, sometimes you need selecting multiple chip in a chip group.
After that it is very tedious task to get their text in easy way.
I found a way and i am sharing with you
In this code i selected chips inside Alert Dialog

val builder = AlertDialog.Builder(requireContext())
       builder.setTitle("Filter")
       val mView = FilterOptionLayoutBinding.inflate(layoutInflater)
       builder.setView(mView.root)

       builder.setPositiveButton(android.R.string.ok) { d, p ->
           mView.chipGroup.checkedChipIds.forEach {
               val chip = mView.root.findViewById<Chip>(it).text.toString()
               checkedChipsText.add(chip)
           }
           d.dismiss()
       }
       builder.setNegativeButton(android.R.string.cancel) { d, _ ->
           d.cancel()
       }
       builder.create()
       builder.show()

Hide Keyboard in Android using Kotlin in 20 second

Write these extension function in utility class to hide the soft keyboard

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)
}

Now use this method in your activity and fragment where you want hide keyboard.

hideKeyboard

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