Fatal Exception: java.lang.UnsupportedOperationException: Failed to resolve attribute at index 5: TypedValue{t=0x2/d=0x7f040109 a=23}

Question

I am facing an error message which triggers whenever I click in a MaterialDatePicker. I think it is related with the ThemeOverlay but I have no idea how can I get rid of it.

This is the error message:

                                                                                                        at androidx.appcompat.widget.AppCompatTextView.<init>(AppCompatTextView.java:108)

It only happens only in the AppThemeDark. Here it is my style sheet:

<style name="AppTheme" parent="Theme.MaterialComponents.Light">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        ....
</style>
<style name="AppThemeDark" parent="ThemeOverlay.MaterialComponents.Dark">
        <!-- Customize your theme here. -->
        <item name="android:windowAnimationStyle">@style/WindowAnimationTransition</item>
        <item name="colorPrimary">@color/background_material_dark</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
       ....
</style>
<style name="MaterialCalendarTheme" parent="ThemeOverlay.MaterialComponents.MaterialCalendar">
        <!-- Buttons -->
        <item name="buttonBarPositiveButtonStyle">@style/TextButton</item>
        <item name="buttonBarNegativeButtonStyle">@style/TextButton</item>
    </style>
    <style name="TextButton" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
        <item name="android:textColor">@android:color/white</item>
    </style>

And this is the Java class:

MaterialDatePicker<Long> datePicker = MaterialDatePicker.Builder
                    .datePicker().setTheme(R.style.MaterialCalendarTheme)
                    .setTitleText("Select date").setSelection(today)
                    .build();
            datePicker.show(getSupportFragmentManager(), "MATERIAL_DATE_PICKER");

I was trying to pop up a MaterialDatePicker in my main activity.

Answer 1

I fixed changing the app theme to Theme.Material3.Dark and adding custom styles in it.
