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>
XML

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>
XML

Where:

  • colorPrimary > Title and Button background color
  • colorOnPrimary > Title and Button text color
  • colorSecondary > Dialog and Row background color
  • colorEdgeEffect > RecyclerView edge color
  • textColorPrimary > Search and Row text color
  • textColorSecondary > Search hint and icon color; Horizontal Lines color
  • colorSurface > CheckBox, RadioButton and Switch unchecked color
  • colorOnSurface > Button background when disabled (note overrides colorSurface)
  • colorAccent > CheckBox, RadioButton and Switch checked color; Hint cursor 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 */ 
        }
Kotlin

Show it when desired:

picker.show(supportFragmentManager, "MyPickerDialogFragment")
Kotlin
