How do I attach multiple room database columns to multiple views in recyclerview?

THIS IS THE VIEWMODEL FILE CODE
class HomePageDocVM(var dao: HomePageEventsDAO) : ViewModel() {
val eventNamevm = dao.getAll()
var newEventName : String = "event nameprop"
var newEventDate : String = "event dateprop"
var newEventTime : String = ""
var selectedTime : String = ""
fun addnew(){
viewModelScope.launch {
var evNamedb = HomePageEventsEntity(0)
evNamedb.EventName = newEventName
var evDatedb = HomePageEventsEntity(0)
evDatedb.EventDate = newEventDate
var evTimedb = HomePageEventsEntity(0)
evDatedb.EventTime = newEventTime
dao.insert(evNamedb, evTimedb, evDatedb)
}
}
}
THIS IS THE ADAPTER FILE CODE
package com.example.projectm.activitiesFragments

{
var eventName : TextView = view.findViewById<TextView>(R.id.text_of_evnt_rv_item)
var eventTime : TextView = view.findViewById<TextView>(R.id.text_of_time_rv_item)
var eventDate : TextView = view.findViewById<TextView>(R.id.text_of_date_rv_item)
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int):
DocUpcomingEventsViewHolder
{
val linearlayout = LayoutInflater.from(parent.context)
.inflate(R.layout.doc_upcoming_events_rv_item, parent, false) as View
return DocUpcomingEventsViewHolder(linearlayout)
}
override fun onBindViewHolder(holder: DocUpcomingEventsViewHolder, position: Int) {

LET ME KNOW IF YOU WANT TO KNOW ANYTHING ELSE REGARDING THIS PROBLEM AND SORRY IF BOLD TEXT SOUNDS RUDE :]

Want to transfer data using livedata, viewmodel between in android fragments

I am currently trying to make a app that calculates a loan plan. User plots in data like loan amount, downpayment years, and how much rent the loan should have. I have implemented edit text for the loan amount, two seekbars for years and rent number.
Since I am fairly new to android programing I am nautraly struggling with implementing MVVM to my app. I implemented databinding, viewmodel and wrote the code to link them togehter. I also get the value out if I use Init in viewmodel, but I dont seem to transfer Int value from seekbar to the next fragment. Do anyone has suggestion to my code?
I am gratefull for any help.
In AnnuitetFragment.kt fragment I have only implemented modelView to RenterAnnSeekBar since I use it for testing.
package com.example.lnognedbetalingsplan.annuitet
import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.SeekBar
import androidx.fragment.app.Fragment
import androidx.lifecycle.ViewModelProvider
import androidx.navigation.fragment.findNavController
import com.example.lnognedbetalingsplan.R
import com.example.lnognedbetalingsplan.databinding.FragmentAnnuitetBinding
import com.example.lnognedbetalingsplan.viewmodel.AnnuitetViewModel
class AnnuitetFragment : Fragment() {
private var _binding: FragmentAnnuitetBinding? = null
private val binding get() = _binding!!
private lateinit var viewModel: AnnuitetViewModel
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?): View {
_binding = FragmentAnnuitetBinding.inflate(inflater, container, false)
return binding.root
}
var startPoint = 0
var endPoint = 0
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
binding.lifecycleOwner = this
viewModel = ViewModelProvider(this)[AnnuitetViewModel::class.java]
binding.viewmodel = viewModel
binding.tilbakeTilVelkommen.setOnClickListener {
findNavController().navigate(R.id.action_annuitetFragment_to_velkommenFragment)
}
binding.BeregnLaanAnnuitet.setOnClickListener {
findNavController().navigate(R.id.action_annuitetFragment_to_annuitetPlanFragment)
}
binding.RenterAnnSeekBar.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {
override fun onProgressChanged(seekBar: SeekBar?, progress: Int, fromUser: Boolean) {
binding.RenterTall.text = progress.toString()
}
override fun onStartTrackingTouch(seekBar: SeekBar?) {
if (seekBar != null){
startPoint = seekBar.progress
}
}
override fun onStopTrackingTouch(seekBar: SeekBar?) {
if (seekBar != null){
endPoint = seekBar.progress
}
}
})
binding.AarSerieSeekBar.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {
override fun onProgressChanged(seekBar: SeekBar?, progress: Int, fromUser: Boolean) {
binding.AarTall.text = progress.toString()
}
override fun onStartTrackingTouch(seekBar: SeekBar?) {
if (seekBar != null){
startPoint = seekBar.progress
}
}
override fun onStopTrackingTouch(seekBar: SeekBar?) {
if (seekBar != null){
endPoint = seekBar.progress
}
}
})
}
}
AnnuitetViewModel.kt is the viewmodel class I am going to use to store livedata so it can share it between AnnuitetFragment.kt and AnnuitetPlanFragment.kt. If this code miss any please help me with some pointers.
package com.example.lnognedbetalingsplan.viewmodel
import android.widget.SeekBar
import androidx.lifecycle.LiveData
import androidx.lifecycle.MutableLiveData
import androidx.lifecycle.Transformations
import androidx.lifecycle.ViewModel
open class AnnuitetViewModel : ViewModel() {
val progress: MutableLiveData<Int> by lazy { MutableLiveData<Int>() }
val renterProgress: LiveData<Int>
get() = progress
init {
progress.value = 1
}
}
My plan AnnuitetPlanFragment.kt is to get data from AnnuitetFragment.kt and calculate the loan plan from user. But when I try to get the data from AnnuitViewModel.kt I get the mock data from Init but there is not data from val progress.
package com.example.lnognedbetalingsplan.annuitet
import android.os.Bundle
import androidx.fragment.app.Fragment
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.Button
import android.widget.TextView
import androidx.lifecycle.Observer
import androidx.lifecycle.ViewModelProvider
import androidx.navigation.fragment.findNavController
import com.example.lnognedbetalingsplan.R
import com.example.lnognedbetalingsplan.databinding.FragmentAnnuitetBinding
import com.example.lnognedbetalingsplan.databinding.FragmentAnnuitetPlanBinding
import com.example.lnognedbetalingsplan.viewmodel.AnnuitetViewModel
import kotlin.math.pow
class AnnuitetPlanFragment : Fragment() {
private var _binding: FragmentAnnuitetPlanBinding? = null
private val binding get() = _binding!!
private lateinit var viewModel: AnnuitetViewModel
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?): View? {
_binding = FragmentAnnuitetPlanBinding.inflate(inflater, container, false)
return binding.root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
binding.lifecycleOwner = this
viewModel = ViewModelProvider(this).get(AnnuitetViewModel::class.java)
binding.viewmodel = viewModel
viewModel.renterProgress.observe(viewLifecycleOwner, Observer { renteTall->
binding.tvTest.text = renteTall.toString()
})
binding.tilbakeTilAnnuitet.setOnClickListener {
findNavController().navigate(R.id.action_annuitetPlanFragment_to_annuitetFragment)
}
}
}
Last one is my fragment_annuitet.xml where I implemented databinding and seekbar gets progress data and show it in viewCreate.

I figured my own question out.
If found out if you share your modelview with the two fragments you want to share data bewteen, and with observer this is possible.
Added this code:
private val AnnuitetViewModel: AnnuitetViewModel by activityViewModels()
Also made observers for every val I wanted to transfer to the next fragment:
AnnuitetViewModel.loanNumber.observe(viewLifecycleOwner){loanNumber->
binding.laanebelop.setText(loanNumber)
}
AnnuitetViewModel.progressRenter.observe(viewLifecycleOwner){progressRenter->
binding.RenterTall.text = progressRenter
}
AnnuitetViewModel.progressAar.observe(viewLifecycleOwner){progressAar->
binding.AarTall.text = progressAar
}
A button listner trigger the transfer to livedata in the viewmodel:
binding.BeregnLaanAnnuitet.setOnClickListener {
AnnuitetViewModel.saveLoanNumber(binding.laanebelop.text.toString())
AnnuitetViewModel.saveProgressRenter(binding.RenterTall.text.toString())
AnnuitetViewModel.saveProgressAar(binding.AarTall.text.toString())
findNavController().navigate(R.id.action_annuitetFragment_to_annuitetPlanFragment)
}
In the viewModel I made some var and val that takes inn the data:
open class AnnuitetViewModel : ViewModel() {
var startPoint = 0
var endPoint = 0
val seekbarRenterProgress: MutableLiveData<Int> by lazy { MutableLiveData<Int>() }
val seekbarAarProgress: MutableLiveData<Int> by lazy { MutableLiveData<Int>() }
private var _loanNumber = MutableLiveData<String>()
val loanNumber: MutableLiveData<String> = _loanNumber
fun saveLoanNumber(newLoanNumber: String){
_loanNumber.value = newLoanNumber
}
private var _progressRenter = MutableLiveData<String>()
val progressRenter: MutableLiveData<String> = _progressRenter
fun saveProgressRenter(newProgressRenter: String){
_progressRenter.value = newProgressRenter
}
private var _progressAar = MutableLiveData<String>()
val progressAar: MutableLiveData<String> = _progressAar
fun saveProgressAar(newProgressAar: String){
_progressAar.value = newProgressAar
}
init {
seekbarRenterProgress.value = 5
seekbarAarProgress.value = 5
}
}
The seekBar and textview look like this in my xml:
<SeekBar
android:id="#+id/AarSerieSeekBar"
android:layout_width="300dp"
android:layout_height="30dp"
android:max="50"
android:min="0"
android:progress="#={viewmodel.seekbarAarProgress}"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.306"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.499" />
<TextView
android:id="#+id/AarTall"
android:layout_width="35dp"
android:layout_height="30dp"
android:text="#={`` + viewmodel.seekbarAarProgress}"
android:textSize="20sp"
android:visibility="#{viewmodel.seekbarAarProgress != null? View.VISIBLE : View.GONE}"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.619"
app:layout_constraintStart_toEndOf="#+id/AarSerieSeekBar"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.499" />
For test if the second fragment can read the data I wrote this code that observe the data and sends it to a textview that comes up when you run the app in a emulator:
AnnuitetViewModel.loanNumber.observe(viewLifecycleOwner, binding.tvTest::setText)
AnnuitetViewModel.progressRenter.observe(viewLifecycleOwner, binding.tvTest2::setText)
AnnuitetViewModel.progressRenter.observe(viewLifecycleOwner, binding.tvTest3::setText)

How to make my Edit and Delete Image functionality in Fragment?

I am trying to implement onEditPost and onDeletePost inside of my RecyclerViewFragment:
import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.ImageView
import androidx.fragment.app.Fragment
import androidx.recyclerview.widget.LinearLayoutManager
import androidx.recyclerview.widget.RecyclerView
import com.example.MainActivity
import com.example.projectdrivemark.R
import com.example.projectdrivemark.databinding.FragmentListBinding
import com.example.projectdrivemark.databinding.PostBinding
class RecyclerViewFragment: Fragment(R.layout.fragment_list), PostAdapter.OnPostClickListener {
private lateinit var binding: FragmentListBinding
val dummyList = MockDatabase.createMockData()
val adapter = PostAdapter(dummyList, this)
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
super.onCreate(savedInstanceState)
binding = FragmentListBinding.inflate(inflater, container, false)
return binding.root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
view.findViewById<RecyclerView>(R.id.recycleViewMain).apply{
layoutManager = LinearLayoutManager(requireActivity())
adapter = PostAdapter(dummyList, this#RecyclerViewFragment)
}
}
override fun onEditPost(position: Int){
val clickedPost = dummyList[position]
clickedPost.title = "Updated title"
clickedPost.body = "Updated body"
adapter.notifyItemChanged(position)
}
override fun onDeletePost(position: Int) {
dummyList.removeAt(position)
adapter.notifyItemRemoved(position)
}
}
Here is how my Adapter looks like:
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.ImageView
import android.widget.TextView
import androidx.recyclerview.widget.RecyclerView
import com.example.MainActivity
import com.example.projectdrivemark.R
class PostAdapter(val dummyData: ArrayList<Post>, val myListener: OnPostClickListener) : RecyclerView.Adapter<PostAdapter.PostViewHolder>() {
inner class PostViewHolder(postView: View) : RecyclerView.ViewHolder(postView), View.OnClickListener{
val iconImage: ImageView = postView.findViewById(R.id.icon_image_view)
val title: TextView = postView.findViewById(R.id.title)
val body: TextView = postView.findViewById(R.id.body)
val deleteIcon: ImageView = postView.findViewById(R.id.delete_post_image)
val editIcon: ImageView = postView.findViewById(R.id.edit_post_image)
init {
deleteIcon.setOnClickListener(this)
editIcon.setOnClickListener(this)
}
override fun onClick(v: View?){
val position = adapterPosition
if(v?.id == editIcon.id){
myListener.onEditPost(position)
}else{
myListener.onDeletePost(position)
}
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): PostViewHolder {
val postView = LayoutInflater.from(parent.context).inflate(R.layout.post, parent, false)
return PostViewHolder(postView)
}
override fun onBindViewHolder(holder: PostViewHolder, position: Int) {
val currentPost = dummyData[position]
holder.iconImage.setImageResource(currentPost.image)
holder.title.text = currentPost.title
holder.body.text = currentPost.body
}
override fun getItemCount(): Int {
return dummyData.size
}
interface OnPostClickListener{
fun onEditPost(position: Int)
fun onDeletePost(position: Int)
}
}
And here is how my XML File Post looks like:

As you see in the RecyclerViewFragment, I have 2 functions that is onEditPost and onDeletePost. I want that functionality to work when I press it. Right now, it only works when I press and change the fragment view. I want it to work instantly. If anyone see my mistake or Am I missing something? please do tell me. All help is appreciate

You are creating Adapter twice, you already have an Adapter initialised globally use it in onViewCreated instead of assign again. because you are using global adapter to notify changes.
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
view.findViewById<RecyclerView>(R.id.recycleViewMain).apply{
layoutManager = LinearLayoutManager(requireActivity())
adapter = this#RecyclerViewFragment.adapter
}
}

How can I do a setOnClickListener to a fragment that is not in my Activity?

I have 3 fragments here I show them, they have a TextView with the id omitir_swipe, and I need to use it in the activity where I show those 3 fragments, how would I achieve it?:
3 fragments xml:

The 3 are the same so I only upload 1, they have the same id, to only use 1, I don't know if this is good, could you tell me whether to change it or not

I don't have any errors but when I uncomment the setOnClickListener it doesn't work it gives me a null pointer exception error, and that is because the id of the omit_swipe is not in the activity xml as you can see above instead it is in the fragments.

You can start a new activity and finish the current from the fragment.
class SwipeFragement1 : Fragment(){
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?

val view = inflater.inflate(R.layout.fragment_splash_screen_1, container, false)

activity.startActivity(intent)
activity.finish()
}
return view
}

RecyclerView doesn't scroll smoothly initially

I'm using Tmdb API and displaying it in a RecyclerView. The RecyclerView is not scrolling smoothly initially but then is working fine. I've tried to change Recyclerview height to 0dp or match_parent but it's still the same. I've tried also android:nestedScrollingEnabled="true". Please help me to fix this problem in the RecyclerView. Thank you in advance.

I believe this is due to size of the image , I had similar issue try to fit the image you obtain using glide into imageview, I have added centerCrop():
Glide.with(context).load("https://image.tmdb.org/t/p/w300${movieList[position].moviePosterPath}") .centerCrop().into(holder.view.recyclerview_movie_item_moviePosterIV);
If this does not work try to change imageview scaletype or centerCrop() to fitCenter()
