How go get both both key and value from firebase database on kotlin-CodePudding

I'm new to android development and im having a bit of problem with firebase database. I'm creating a app somewhat similar to e-commerce application.

category1
    child1
         name: nameOfChild1
         value: value
    child2
         name: nameOfChild2
         value: value
    child3

This is how my database is structured. im using

dbref = FirebaseDatabase.getInstance().getReference("requiredCategory")
        dbref.addValueEventListener(object : ValueEventListener {
            override fun onDataChange(snapshot: DataSnapshot) {
                if (snapshot.exists()) {
                    for (productSnapshot in snapshot.children) {
                        val product = productSnapshot.getValue(Product::class.java)
                        productlist.add(product!!)
                    }
                    productrecyclerview.adapter = productAdapter(productlist)
                }
            }

And Product class is

data class Product(
    var id: String? = null,
    var price: String? = null,
)

Instead i would like to change my structure to

category1
    child1
      nameOfNested1: value
      nameOfNested2: value
    child2
      nameOfNested1: value
      nameOfNested2: value
    child3
      nameOfNested1: Value
      nameOfNested2: value

category2
    child1
    child2
    child3

I want to retrive both the key: nameOfNested and value:value .How do i go on and change the code get both the id and value? Thanks in Advance

CodePudding user response：

If you also want to get the key of each product, you can do so with:

for (productSnapshot in snapshot.children) {
    val key = productSnapshot.key //
