hey so I’m trying to make a simple seekbar but I’m facing some weird problems.
I programmed an app in kotlin about a year ago and it was different from what I’m experiencing now. first of all, why can I only initialize with lateinit? and then I can only access variables inside onCreate? anyway i was trying to make a seekbar but for some reason
kotlin does not recognize it like it dosent understand what I’m trying to do
the code:
class Generator : AppCompatActivity() {
lateinit var username: EditText
lateinit var app: EditText
lateinit var password: TextView
lateinit var caps: Switch
lateinit var numbers: Switch
lateinit var symbols: Switch
lateinit var seekbarvalue: TextView
lateinit var length: SeekBar
lateinit var generate: Button
lateinit var copy: Button
lateinit var save: Button
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_generator)
username = findViewById<EditText>(R.id.username)
app = findViewById<EditText>(R.id.app)
password = findViewById<TextView>(R.id.password)
caps = findViewById<Switch>(R.id.caps)
numbers = findViewById<Switch>(R.id.numbers)
symbols = findViewById<Switch>(R.id.symbols)
seekbarvalue = findViewById<TextView>(R.id.seekbarvalue)
length = findViewById<SeekBar>(R.id.length)
generate = findViewById<Button>(R.id.generate)
copy = findViewById<Button>(R.id.copy)
save = findViewById<Button>(R.id.save)
length.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener){
override fun onProgressChanged(p0: SeekBar?, p1: Int, p2: Boolean) {
}
}
}
}
>Solution :
length.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {
override fun onProgressChanged(p0: SeekBar?, p1: Int, p2: Boolean) {
}
override fun onStartTrackingTouch(p0: SeekBar?) {
TODO("Not yet implemented")
}
override fun onStopTrackingTouch(p0: SeekBar?) {
TODO("Not yet implemented")
}
})
