I have a strange problem. I have made ripple_effect.xml which I use in RecyclerView.

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:state_pressed="true">         <shape android:shape="rectangle">             <solid android:color="#4F66FF" />         </shape>     </item>     <item>         <shape android:shape="rectangle">             <solid android:color="#ffffff" />         </shape>     </item> </selector> 

Single view

<?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:focusable="true"     android:clickable="true"     android:background="@color/ripple_effect">      <ImageView         android:id="@+id/iv_view_category"         android:layout_width="match_parent"         android:layout_height="0dp"         android:adjustViewBounds="true"         android:clickable="false"         android:focusable="false"         android:padding="8dp"         app:layout_constraintEnd_toEndOf="parent"         app:layout_constraintStart_toStartOf="parent"         app:layout_constraintTop_toTopOf="parent" />  </androidx.constraintlayout.widget.ConstraintLayout> 

Adapter

class AdapterCategory(private val list: List<Category>, private val iOnClickHandler: IonClick, private val context: Context) : androidx.recyclerview.widget.RecyclerView.Adapter<AdapterCategory.ViewHolder>() {      inner class ViewHolder internal constructor(itemView: View) : androidx.recyclerview.widget.RecyclerView.ViewHolder(itemView), View.OnClickListener {          internal var picture: ImageView          init {             itemView.setOnClickListener(this)             this.picture = itemView.findViewById(R.id.iv_view_category)         }          override fun onClick(v: View) {             itemView.isEnabled = false             itemView.postDelayed(Runnable { itemView.isEnabled = true }, 500)             iOnClickHandler.onItemClick(adapterPosition)         }     }      override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {         val view = LayoutInflater.from(parent.context)                 .inflate(R.layout.view_category, parent, false)         return ViewHolder(view)     }      override fun onBindViewHolder(holder: ViewHolder, position: Int) {         val ivImage = holder.picture         val icon = ContextCompat.getDrawable(context, list[position].image)          ivImage.setImageDrawable(icon)     }      override fun getItemCount(): Int {         return list.size     }      interface IonClick {         fun onItemClick(position: Int)     } } 

I have received few recording from testing devices from Google, and on few models the color #4F66FF is violet. Here is list devices where code works fine:

• Redmi 5 Plus – MIUI 11.0.2
• Motorola XT1650 – Android 7.0 Samsung
• Galaxy S9 G960U1 – Android 8
• Xperia XZ1 G8441 – Android 8
• Nokia 1 FRT -Android 8.1.0
• LG AS110 – Android 6.0.1
• Pixel 3 – Android 9
• P8 Lite – Android 5.0.1
• Pixel – Android 7.1.2

Color is wrong for these devices:

• Redmi Note 8 Pro – MUI 11
• P30 Pro – EMUI 10
• Xiaomi Mi 9t – Android 10
• Pixel 4 – Android 10

Imho as I can see problem is only on Android 10. Why? Any nice solutions to make what I want but in different way? Thanks!
