This is my GenericTextEnterPin Class

     class GenericTextEnterPinPassword (private val view: View, private val editText: ArrayList<EditText>) : TextWatcher {
        
            override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
            }
        
            override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
            }
        
            override fun afterTextChanged(s: Editable?) {
                val string = s.toString()
                when (view.id) {
                    R.id.otp_edit_box5 -> {
                        if (string.length == 1) editText[1].requestFocus()
                    }
                    R.id.otp_edit_box6 -> {
        
                        if (string.length == 1) editText[2].requestFocus() else if (string.isEmpty()) editText[0].requestFocus()
                    }
                    R.id.otp_edit_box7 -> {
                        if (string.length == 1) editText[3].requestFocus() else if (string.isEmpty()) editText[1].requestFocus()
                    }
                    R.id.otp_edit_box8 -> {
                        if (string.isEmpty()) editText[2].requestFocus()

CodePudding user response：

You can pass your callback as a lambda function to GenericTextEnterPinPassword.

class GenericTextEnterPinPassword (
    private val view: View, 
    private val editText: ArrayList<EditText>,
    private val callback: () -> Unit
): TextWatcher {
    // ...
    R.id.otp_edit_box8 -> {
        if (string.isEmpty()) editText[2].requestFocus()
        callback()    
    }
    // ...
}

Usage:

val textWatcher = GenericTextConfirmPassword(otp_edit_box11, edit) {
    // Whatever you wish to do upon callback
}
otp_edit_box11.addTextChangedListener(textWatcher)
