I have this line in my account_particle.xml layout
android:padding="?attrs/disc_padding"
this attrs.xml:
<resources>
<declare-styleable name="AccountParticle">
<attr name="text_margin_start" format="reference"/>
<attr name="disc_padding" format="reference"/>
<attr name="disc_imageViewSize" format="reference"/>
</declare-styleable>
</resources>
and this styles.xml:
<style name="Theme.ap.header" parent="Theme.AppCompat">
<item name="disc_padding">@dimen/account_menu_header_signed_in_avatar_margin_start</item>
</style>
<style name="Theme.ap.list_item" parent="Theme.AppCompat">
<item name="disc_padding">@dimen/account_menu_account_list_item_avatar_margin_start</item>
</style>
Why do i get this compilation error?
error: Error: No resource found that matches the given name (at 'padding' with value '?attrs/disc_padding').

Try to replace android:padding="?attrs/disc_padding"
with android:padding="?attr/disc_padding"
or android:padding="?disc_padding"
