I have tried commenting everything out line by line, however I can't seem to find the source of the problem.
Kotlin code
package com.example.mycalculatorapp
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import android.widget.Button
import android.widget.TextView
import android.widget.Toast
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
var tv_input = findViewById<TextView>(R.id.tv_input)
var lastnumeric = false
var lastdot = false
fun onDigit(view: View) {
tv_input.append((view as Button).text)
lastnumeric = true
}
fun Onclear (view: View){
tv_input.text = ""
lastnumeric = false
lastdot = false
}
fun ondecimalpoint(view: View){
if(lastnumeric && !lastdot){
tv_input.append(".")
lastnumeric = false
lastdot = true
}
}
fun onoperator(view: View){
if(lastnumeric && !isoperatoraddded(tv_input.text.toString())){
tv_input.append((view as Button).text)
lastnumeric = false
lastdot = true
}
}
private fun isoperatoraddded(value:String):Boolean{
return if (value.startsWith("-")){
false
}else{
value.contains("/") || value.contains("*")
||value.contains("+")|| value.contains("-")
}
}
}
