Hi I am new to kotlin and have come across few issues, please could someone support me.
I have trying to create a app where user get asked 10 question with Pass or Fail option.
I have following coding in Button_Activity.
package com.example.myapplication
import android.os.Bundle
import android.view.View
import android.widget.RadioButton
import android.widget.RadioGroup
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import kotlinx.android.synthetic.main.activity_button.*
class ButtonActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_button)
// Get radio group selected item using on checked change listener
radiogrouppassfail.setOnCheckedChangeListener(
RadioGroup.OnCheckedChangeListener { group, checkedId ->
val radio: RadioButton = findViewById(checkedId)
Toast.makeText(
applicationContext, " On checked change : ${radio.text}",
Toast.LENGTH_SHORT
).show()
})
// Get radio group selected status and text using button click event
button_apply_passfail.setOnClickListener {
// Get the checked radio button id from radio group
var id: Int = radiogrouppassfail.checkedRadioButtonId
if (id != -1) { // If any radio button checked from radio group
// Get the instance of radio button using id
val radio: RadioButton = findViewById(id)
Toast.makeText(
applicationContext, "On button click : ${radio.text}",
Toast.LENGTH_SHORT
).show()
} else {
// If no radio button checked in this radio group
Toast.makeText(
applicationContext, "On button click : nothing selected",
Toast.LENGTH_SHORT
).show()
}
}
}
// Get the selected radio button text using radio button on click listener
fun checkButtonPassFail(view: View) {
// Get the clicked radio button instance
val radio: RadioButton = findViewById(radiogrouppassfail.checkedRadioButtonId)
Toast.makeText(
applicationContext, "On click : ${radio.text}",
Toast.LENGTH_SHORT
).show()
}
}
