How to Add and Remove Animation RecyclerView's items

I'm making a music app. I have a recyclerview and I am playing clicked item's music, at the same time animation works too. Question is whenever user change the recyclerview's item position I need to cancel first animation and start new one for new position. I mean every time will be just 1 animation exist.
My RecyclerViewAdapter
class RecyclerViewAdapter(private val ModelList:List<Musics>,private val listener:
ClickListener) :RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>(){
class ViewHolder(var binding:GridListBinding):RecyclerView.ViewHolder(binding.root) {
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val inflater = LayoutInflater.from(parent.context)
val view = DataBindingUtil.inflate<GridListBinding>(inflater,R.layout.grid_list,parent,false)
return ViewHolder(view)
}
override fun onBindViewHolder(holder: RecyclerViewAdapter.ViewHolder, position: Int) {
holder.binding.musics = ModelList[position]
holder.binding.constraint.setOnClickListener{
listener.buttonClicked(holder.binding.constraint,ModelList[position],position)
}
}
override fun getItemCount(): Int {
return ModelList.size
}
}
My ClickListener for adapter
interface ClickListener {
fun buttonClicked(view: View,model: Musics,position:Int)
}

Android kotlin / java - ReclerView strange behavior when hiding parts in holder / xml

I didn't know what proper title for this issue could be.
I'm doing a chat app and this is the part inside the adapter:
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val msg = messages[position]
if (msg.who == "you"){
holder.messagemelayout.visibility = View.GONE
holder.messageyou.text = msg.message
}else{
holder.messageyoulayout.visibility = View.GONE
holder.messageme.text = msg.message
}
}
So when the message is sent be me then the layout for "you" (messageyoulayout) get's hidden and vice versa
Not when I add new messages like this:
var count = 1
bbb.setOnClickListener {
messageslist.add(Chat("hey " + count.toString(), "me"))
adapter.notifyItemInserted(adapter.itemCount - 1)
count++
}
The result is this:
And when I don't hide any layouts then the text inside the layout which don't get any update is still getting filled by random old stuff:
I hope the issue is understandable.
How can I fix this? Like completely removing the layout which don't get an update or something.
Thanks in advance
EDIT:
Whole adapter:
class ChatAdapter(val context: Context, private val messages: MutableList<Chat>) : RecyclerView.Adapter<ChatAdapter.ViewHolder>(){
override fun onBindViewHolder(holder: ViewHolder, position: Int) {

holder.messageyou.text = msg.message
holder.messageme.text = ""
holder.messageme.setBackgroundResource(0)
holder.messageyou.setBackgroundResource(R.drawable.round_corners_lightgray_color)
}else{
holder.messageme.text = msg.message
holder.messageyou.text = ""
holder.messageme.setBackgroundResource(R.drawable.round_corners_accent_color)
holder.messageyou.setBackgroundResource(0)
}
}
override fun getItemCount() = messages.size
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val view = LayoutInflater.from(parent.context).inflate(R.layout.chat, parent, false)

Don't call it bugged mess when you don't understand how ViewHolder pattern works.
You should have used multiple itemViewTypes instead of flipping views visibility back-to-back (note this entire code goes into your RecyclerView.Adapter):
// constants
companion object {
const val TYPE_YOU = 1
const val TYPE_ME = 2
}
/* This method is called to determine what type of ViewHolder should be used to represent item at [position] */
override fun getItemViewType(position: Int) = if(messages[position].who == "you") TYPE_YOU else TYPE_ME
/* [viewType] determines what ViewHolder we should create. */
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
val layoutId = when(viewType){
TYPE_YOU -> {
// this viewholder will display only messages from "you", inflate only "you" layout
R.layout.chat_item_you
}
TYPE_ME ->{
// this viewholder will display only messages from "me", inflate only "me" layout
R.layout.chat_item_me
}
else -> throw IllegalArgumentException("Unknown viewType: $viewType")
}
val itemView = LayoutInflater.from(parent.context).inflate(layoutId, parent, false)
return ViewHolder(itemView)
}
// then you can use your original bind method, because "you" and "me" messages will never re-user others ViewHolder
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val msg = messages[position]
if (msg.who == "you"){
// holder.itemViewtype should always be equal to TYPE_YOU here
}else{
// holder.itemViewtype should always be equal to TYPE_ME here
}
holder.message.text = msg.message
}
class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView){
val txtMessage : TextView = itemView.findViewById(R.id.message)
}
Then split chat bubbles into two separate layouts:
chat_item_you.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_margin="6dp"
android:layout_height="wrap_content">
<TextView
android:id="#+id/message"
style="#style/ChatBubbleStyle"
android:background="#drawable/round_corners_lightgray_color"
android:text="TextView"
android:layout_gravity="end" />
</FrameLayout>
And similar but with other color and gravity:
chat_item_me.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_margin="6dp"
android:layout_height="wrap_content">
<TextView
android:id="#+id/message"
style="#style/ChatBubbleStyle"
android:background="#drawable/round_corners_blue_color"
android:text="TextView"
android:layout_gravity="start" />
</FrameLayout>
Use shared style in styles.xml to prevent redundant code:
<style name="ChatBubbleStyle">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:paddingLeft">8dp</item>
<item name="android:paddingTop">6dp</item>
<item name="android:paddingRight">8dp</item>
<item name="android:paddingBottom">6dp</item>
<item name="android:textColor">#android:color/black</item>
<item name="android:textSize">16sp</item>
</style>

After tryng to set width/height of non used holder to 0, removing background and some other stuff which all "worked" but created other strange behaviors I found the only working non bugged solution:
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val msg = messages[position]
if (msg.who == "you"){
holder.messageyou.text = msg.message
holder.messageme.text = ""
holder.messageme.setBackgroundResource(0)
holder.messageyou.setBackgroundResource(R.drawable.round_corners_lightgray_color)
}else{
holder.messageme.text = msg.message
holder.messageyou.text = ""
holder.messageme.setBackgroundResource(R.drawable.round_corners_accent_color)
holder.messageyou.setBackgroundResource(0)
}
}
Yes you have to define the background on BOTH layouts over and over again and tell the holder that there is nothing to fill where it really isn't. Android is a bugged time wasting mess..

Drawer Scrolling Slowly

I have this drawer which opens normally but the scrolling in it is very slow, and I don't know why knowing that the image it has on top of it is not HD image, and available in the 4 sizes, I've done various examples in Java and it was fine, I wonder if the issue is that I'm using Kotlin in the adapter.
I would appreciate any help.

What should I change, the activity layout, or the adapter or what i realy have no idea.
EDIT
I set the visibility of the marquee text view in the layout to gone, and everything worked just fine, does anybody know why? because I don't want to replace this text view with a horizontal recycler view

SOLVED.
Changed the approach completely, I stopped the marquee and applied cross fade animation to the text view, with a handler that changes the object being set in the text view at each iteration, and now it looks perfect and way more elegnat
