I would appreciate it if you could help me.



activity.kotlin



var postsMap = HashMap<>() //Here error
postsMap.put("uid", current_user_id)
postsMap.put("date", saveCurrentDate)
postsMap.put("time", saveCurrentTime)
postsMap.put("description", Description)
postsMap.put("postimage", downloadUrl)
postsMap.put("profileimage", userProfileImage)
postsMap.put("fullname", userFullName)
PostsRef.child(current_user_id + postRandomName).updateChildren(postsMap)//Here error
.addOnCompleteListener(object : OnCompleteListener {//Here error
override fun onComplete(task: Task<*>) { //Here error
if (task.isSuccessful) {
SendUserToMainActivity()
Toast.makeText(
this@PostActivity,
"New Post is updated successfully.",
Toast.LENGTH_SHORT
).show()

} else {
Toast.makeText(
this@PostActivity,
"Error Occured while updating your post.",
Toast.LENGTH_SHORT
).show()

}
}
})


sorry for the inaccurate question.
Thank you



I corrected the code through answer. Thank you.



val postsMap: HashMap = hashMapOf()



PostsRef!!.child(current_user_id + postRandomName).updateChildren(postsMap)

    What does your IDE tell you about the underlined parts of code?

  • Have you tried to write the code in Java and get Android Studio (I'm assuming you're using Android Studio) to convert the code for you and see how it converts it to understand what's going wrong?
