In Kotlin, You may use bellow like.. It is working fine

editText1.setOnKeyListener(View.OnKeyListener { v, keyCode, event ->
        if (keyCode == KeyEvent.KEYCODE_DEL && event.getAction() == KeyEvent.ACTION_DOWN) {
            //Perform Code

            if(editText1.hasFocus()){
                editText1.setText("")
                editText1.requestFocus()
                return@OnKeyListener true
            }
            //return@OnKeyListener true
        }
        false
    })

    editText2.setOnKeyListener(View.OnKeyListener { v, keyCode, event ->
        if (keyCode == KeyEvent.KEYCODE_DEL && event.getAction() == KeyEvent.ACTION_DOWN) {
            //Perform Code
            if(editText2.hasFocus()){
                //txtOTP_2.requestFocus()
                editText2.setText("")
                editText1.requestFocus()
                return@OnKeyListener true
            }
            //  return@OnKeyListener true
        }
        false
    })

    editText3.setOnKeyListener(View.OnKeyListener { v, keyCode, event ->
        if (keyCode == KeyEvent.KEYCODE_DEL && event.getAction() == KeyEvent.ACTION_DOWN) {
            //Perform Code
            if(editText3.hasFocus()){
                //txtOTP_2.requestFocus()
                editText3.setText("")
                editText2.requestFocus()
                return@OnKeyListener true
            }
            //return@OnKeyListener true
        }
        false
    })

    editText4.setOnKeyListener(View.OnKeyListener { v, keyCode, event ->
        if (keyCode == KeyEvent.KEYCODE_DEL && event.getAction() == KeyEvent.ACTION_DOWN) {
            //Perform Code
            if(editText4.hasFocus()){
                // txtOTP_4.requestFocus()
                editText4.setText("")
                editText3.requestFocus()
                return@OnKeyListener true
            }
            // return@OnKeyListener true
        }
        false
    })
