Increment and decrement EditTextInput

Issue

is there a way to do this:

  var num = 0
    plusbtn.setOnClickListener {
        num++
        textView2.text = num.toString()
    }
    minbtn.setOnClickListener {
        num--
        textView2.text = num.toString()
    }

but instead of the textView2, I use a inputtype thing. So that I can still type the numbers in it, but also use the 2 buttons to increment en decrement.

Solution

I have made this. This now works as I want it to:

 plusbtn.setOnClickListener {
        if(isEmpty(penaltytimetxt.text)){
            penaltytimetxt.setText("0")
        }
        num = penaltytimetxt.text.toString().toInt()
        if(num < 99){
            num++
            penaltytimetxt.setText(num.toString())
        }
        else {
            Toast.makeText(this, "Penalty time cannot go over 99 sec", Toast.LENGTH_SHORT).show()
        }
    }
 minbtn.setOnClickListener {
        if(isEmpty(penaltytimetxt.text)){
            penaltytimetxt.setText("0")
        }
        num = penaltytimetxt.text.toString().toInt()
        if(num > 0){
            num--
            penaltytimetxt.setText(num.toString())
        }
        else {
            Toast.makeText(this, "Penalty time cannot go under 0 sec", Toast.LENGTH_SHORT).show()
        }
    }
