Android Obtain all the children that a Layout has (Including Sub-childs)

Basically what im trying to do is create a function that has a recursive calling, so i can obtain all the RadioButtons, Buttons, FAB, TextView, and even others SubViews ( LinearLayouts, RelativeLayouts, FrameLayout, ViewGroup ). Right now i can obtain all the Layouts but when i wanna access the subcontent of those subViews those values never return...

var contentList = ArrayList<String>()

fun ManageView(viewGroup: ViewGroup, action: String, context: Activity){
try {
loop@ for (i in 0 until viewGroup.childCount) {
var child = viewGroup.getChildAt(i)
contentList.add(context.applicationContext.resources.getResourceEntryName(child.id))
when (child) {
is ViewGroup->{
ManageView(child,"vacant",context)
}
is RadioGroup -> {
contentList.add(context.applicationContext.resources.getResourceEntryName(child.id))
}
}
}
println("TOTAL OF ELEMENTS: " + contentList.size)
contentList.forEach { list ->
println("Data: " + list)
}
}catch (exception: Exception){
println("Houston we have a layout problem")
}
}


and the values that i got are:

07-01 07:35:40.543 30090-30090/com.epictech.epiccab_driver I/System.out: TOTAL OF ELEMENTS: 18
Data: framePrice
Data: lblRate
Data: viewInclude
Data: layoutPaidHired
Data: viewSeparator
Data: idPaidSign
Data: txtPaidResult
Data: viewSeparatorRight
Data: containerHiredDetails
Data: layoutHiredPays
Data: viewSeparatorPaidRight
Data: frameTripRateInfo
07-01 07:35:40.544 30090-30090/com.epictech.epiccab_driver I/System.out: Data: fragment_fragment_trip_info
Data: frameContainer
Data: layoutDriverData
Data: menu
Data: layoutFAB
Data: layoutSpeedometer


However in my xml i got a lot of Content that has a mix of FrameLayout, Relative and Linear. This is an example:

MainActivity

<?xml version="1.0" encoding="utf-8"?>

To collect all the RadioButton views(as specified in your example) just change your code as follows. To collect more types put them in the same when block:

RadioButton

when

var contentList = ArrayList<String>()
fun ManageView(view: View, action: String, context: Activity) {

try {
// if you want all the views then add elements to the list without any when
when (view) {
is RadioGroup -> {
loop@ for (j in 0 until view.childCount){
val child = view.getChildAt(j)
contentList.add(context.applicationContext.resources.getResourceEntryName(child.id))
}
}
//add more cases here to collect more types
// all the view types that you'd like to collect must be put here
}
println("TOTAL OF ELEMENTS: " + contentList.size)
contentList.forEach { list ->
println("Data: " + list)
}
if (view is ViewGroup) {
loop@ for (i in 0 until view.childCount) {
val child = view.getChildAt(i)
when (child) {
is ViewGroup -> {
ManageView(child, "vacant", context)
}
}
}
}
}catch (exception: Exception){
println("Houston we have a layout problem")
}
}
