    Also receive such error in logcat:

    "E/ThemeUtils: View class TableCircleCustomView is an AppCompat widget that can only be used with a Theme.AppCompat theme (or descendant)."

    My app theme is "Theme.AppCompat.Light.NoActionBar"

    Here is my custom view class:

    class TableCircleCustomView @JvmOverloads constructor(
        context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
    ) : AppCompatTextView(context, attrs, defStyleAttr) {
        ....
    }
    

    Then in Fragment i'm adding this object to RelativeLayout like so

    val viewItem = TableCircleCustomView(context)     
    with(RelativeLayout.LayoutParams(objectWidth, objectHeight)) {
      leftMargin = objectPosX
      topMargin = objectPosY
        
      binding.restaurantMap.addView(viewItem, this);
    }
    

    Can somebody help to solve it. Have no idea for what element i should set theme and how ((
