So I think I'm having some scoping issues.
I'm trying to use the function setZipEdit to set the R.id.zipHolder
editText
in my activity. I'm just having issues in setting up the code to be able to do this. Below is what I have which isn't currently working. mZipHold
is coming back as not initialized
which I though it was in the override
UPDATED
class SecondActivity : AppCompatActivity() {
lateinit var townInfo:JsonArray<JsonObject>
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity2)
SET_TOWN.setOnClickListener {v -> setTowns()}
GET_TOWNS.setOnClickListener {v -> retrieveTowns()}
}
fun setZipEdit(zipEdit:String){
Log.d("SZE",zipEdit)
zipHolder.setText(zipEdit)
//mZipHold.setText(zipEdit,TextView.BufferType.EDITABLE)
}
