Android: AlertDialog with custom style in MaterialTheme throws resource not found exception

Question

I have the theme Theme.MaterialComponents.Light.NoActionBar in my styles as the main Apptheme.

My alert theme is

<style name="MyDialogTheme" parent="ThemeOverlay.MaterialComponents.Dialog.Alert">
        <item name="android:windowBackground">@drawable/alert_bg</item>
        <item name="android:textColor">@color/text</item>
    </style>

I build my alert dialogue like this

AlertDialog.Builder builder = new AlertDialog.Builder(AllowanceActivity.this, R.style.MyDialogTheme);

when I run it without the style it runs properly but it crashes if I use any other style I've tried with all the themes extending alert Theme.AppCompat.Light.Dialog.Alert and Theme.AppCompat.Dialog.Alert and Theme.MaterialComponents.Dialog.Alert but I always get the error.

is anyone having the same problem or am I missing something

Answer 1

Use the MaterialAlertDialogBuilder which configures the instantiated AlertDialog with Material specs and theming.

Something like:

new MaterialAlertDialogBuilder(context,
                 R.style.MyThemeOverlay_MaterialComponents_MaterialAlertDialog)
            .setTitle("Dialog")
            //...
            .show();

Also use this parent style ThemeOverlay.MaterialComponents.MaterialAlertDialog.
