Android MaterialAlertDialog without extending Theme.MaterialComponent

Question

I'm extending from 'Theme.AppCompat.Light.NoActionBar' and I don't want to switch my AppTheme to MaterialDesign

MaterialAlertDialogBuilder(context, R.style.MaterialDialog)
            .setCancelable(false)
            .setMessage(message)
            .setPositiveButton("OK") { dialog, _ -> dialog.dismiss() }
            .show()

<style name="MaterialDialog" parent="Theme.MaterialComponents.Light.NoActionBar">
        <item name="colorSurface">#ffffff</item>
    </style>

Answer 1

If you can't move to a Material Components Theme you should use a Bridge theme. Something like:

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar.Bridge">
    <item name="colorSurface">#ffffff</item>
    ...
</style>

Then in your code just use:

MaterialAlertDialogBuilder(context)
   .setCancelable(false)
   ...

If you want to override the colors only for the dialog just use:

MaterialAlertDialogBuilder(context,R.style.MaterialDialog)
   .setCancelable(false)
   ...

with:

  <style name="MaterialDialog" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
    <item name="materialThemeOverlay">@style/AlertDialogOverlay</item>
  </style>  


  <style name="AlertDialogOverlay">
    <item name="colorOnSurface">@color/....</item>
    <item name="colorSurface">#ffffff</item>
    <item name="colorPrimary">@color/.....</item>
    ....
  </style>
