var isChoiceMandatory = false
var data: ArrayList<Item> = arrayListOf()
@AnimRes var itemsLayoutAnimator: Int? = null
var dialogHeight: Int = ViewGroup.LayoutParams.MATCH_PARENT

Avoid Memory Leaks

Just add the following line to avoid memory leak if not dismissed before activity or fragment are destroyed:

picker.newInstance(/* setup... */).apply { lifecycleOwner = this@MainActivity }

Themes

To override default theme just create yours by simply extending it and replacing desired color values:

<style name="DialogA" parent="RecyclerPickerDialogTheme">
    <item name="colorPrimary">@color/red</item>
    <item name="recyclerPickerDialogCornerRadius">20dp</item>
</style>

Attributes

You can override the following attributes:

<resources>
    <style name="RecyclerPickerDialogTheme" parent="Theme.MaterialComponents.Light.Dialog">
        <item name="colorPrimary"/>
        <item name="colorOnPrimary"/>
        <item name="colorSecondary"/>
     
        <item name="android:textColorPrimary"/>
        <item name="android:textColorSecondary"/>

        <item name="colorAccent"/>
        <item name="android:colorEdgeEffect"/>
        <item name="recyclerPickerDialogCornerRadius"/>
    </style>
</resources>

Where:

• colorPrimary > Title and Button background color
• colorOnPrimary > Title and Button text color
• colorSecondary > Dialog and Row background color
• colorEdgeEffect > RecyclerView edge color

• recyclerPickerDialogCornerRadius > Dialog corners radius

Creating new instance:

val picker = 
    RecyclerPickerDialogFragment
        .newInstance(
            type = SelectionType.SINGLE, //default
            selector = SelectorType.CHECK_BOX, //default
            theme = R.style.RecyclerPickerDialogTheme, //default
            onItemsPicked = { selected -> /* selected items or empty */ }
        )
        .apply {
            /* configure custom fields */ 
        }
