home.setOnClickListener({
val database = FirebaseDatabase.getInstance()
val child_myRef = database.getReference("users")
child_myRef.addValueEventListener(object : ValueEventListener(){
override fun onDataChange(p0: DataSnapshot?){
val list = mutableListOf<String>()
val it : Iterable<DataSnapshot> = p0!!.children
it.forEach{
val itr=it.children
var msg=" "
itr.forEach({
msg=msg+"n" + it.value
})
list.add(msg)
}
val myadapter = ArrayAdapter<String>(this@HomeActivity, android.R.layout.simple_list_item_single_choice,list)
Lview.adapter = myadapter

If the app crashes, there is a stack trace. Please look that up on logcat, and add it to your question.
