how to keep onPrgressChanged from updating when I change edit field - android-edittext

Question

I have created a Seekbar and have coded it to update an Editable text field with a number based on what the seekBar is moved to. I also have set the seekBar to be updated when I type into the editable text field. However, what I don't want is the Editable text to update from the seekBar change every time I type one number into the Editabl text field. It is causing the cursor to move to the front of the editabl text field every number I type.
here is some of the code I have:
private const val TAG = "MainActivity"
private const val INITIAL_OUNCE_AMOUNT = 0.0
class MainActivity : AppCompatActivity() {
private lateinit var etEditOunceAmount: EditText
private lateinit var seekBarTip: SeekBar
private lateinit var tvNumberOunces: TextView
private lateinit var seekBarOunces: SeekBar
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
etEditOunceAmount = findViewById(R.id.etEditOunceAmount)
seekBarOunces = findViewById(R.id.seekBarOunces)
tvNumberOunces = findViewById(R.id.tvNumberOunces)
seekBarOunces.progress = INITIAL_OUNCE_AMOUNT.toInt()
tvNumberOunces.text = "$INITIAL_OUNCE_AMOUNT"
Below is the meet of whats going on:
seekBarOunces.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {
override fun onProgressChanged(seekBar: SeekBar?, progress: Int, fromUser: Boolean) {
Log.i(TAG, "onProgressChanged $progress")
val str = ("$progress")
val nStr = str.toFloat1()
val aStr = nStr * 0.5
val rStr = aStr.toString()
tvNumberOunces.text = ("$rStr OZ.")
etEditOunceAmount.setText("$rStr")
//computeTipAndTotal()
}
override fun onStartTrackingTouch(seekBar: SeekBar?) {}
override fun onStopTrackingTouch(seekBar: SeekBar?) {}
})
etEditOunceAmount.addTextChangedListener(object : TextWatcher {
override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
if (!etEditOunceAmount.equals(null)) {
var NEW_S = s.toString().toFloatOrNull()
if (NEW_S != null) {
NEW_S = NEW_S * 2
}
if (NEW_S != null) {
seekBarOunces.progress = NEW_S.toInt()
}
}
}
override fun afterTextChanged(s: Editable?) {
}
override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
}
})
}
}
