Here is the code

val db = Firebase.firestore

val user = hashMapOf(
    "name" = "{binding.edit_name.text.toString()}",
    "email" = "{binding.edit_email.text.toString()}
)
binding.submitBtn.setOnClickListener{
    db.collection("users").add(user)
        .addOnSuccessListener {
            Toast.makeText(context,"Data inserted",Toast.LENGTH_LONG).show()
        }
        .addOnFailureListener {
            Toast.makeText(context,"Error",Toast.LENGTH_LONG).show()
        }
}

In above code edit_name , edit_text is input taken by keyboard. I can't able to store the user in firestore. I think there is problem of converting bindig.edit_name.text.toString() it can't able to convert string. If i use hash map without taking input from keyboard as below then I am able to insert data in firestore.

val user = hashMapOf(
    "name" to "ABC",
    "email" to "abc@gmail.com"
)

This hash map is able to add in firestore.

I think there is problem in binding and I am also can't able to toast bindg.edit_name.toString() as shown below

binding.submitBtn.setOnClickListener{
    Toast.makeText(context,"${binding.edit_name.text.toString()},Toast.LENGTH_LONG).show()
}

Please help in this. I think all problem is that I can't able to convert binding data value as a string (by default it is Editable).

According to the official documentation your code seems fine from the point of view of inserting data.

The issue seems indeed to rely on "binding.variable_input.text.toString()".

While investigating the Android Data Binding Library I came across this post, which recommends instead of using toString(), use:

  • String.valueOf(), or if you want to use toString(), try

  • Integer.valueOf().toString()

    Your suggested link and answer for xml not for fragment. I want to convert binding data in kotlin fragment file then I want to add in database. Without converting in string it is not able to insert in db because type of binding data is Editable. – Vikas Kumar Oct 07 '20 at 04:22
  • Could you please elaborate further on how you are storing the text input in binding? – Artemis Georgakopoulou Oct 07 '20 at 13:11
  • I have taken input from keyboard then I stored in variable using binding `val name = binding.name.text.toString()` but due to this I can't able store in db... If you see above my ques with code my question will be cleared – Vikas Kumar Oct 08 '20 at 07:00
  • If I am using binding in my fragment then if we take input from keyboard then that input will be visible in **Kotlin file** by binding.text.toString() but it is not able to add in db – Vikas Kumar Oct 08 '20 at 07:02

  1. Expressions cannot be used for assignments in HashMap, so probably worth changing hashMapOf( "name" to "{binding.name.text.toString()}", "email" to "{binding.email.text.toString()}")

  2. Better assign val name = binding.name.text.toString() and then hashMapOf( "name" to name)

  3. Even better to create a custom object and set the values.

    data class UserInfo (val name: String? = "",val email: String? = "") { constructor(): this("","")}
