I have an app that shows Warning:

Possible overdraw: Root element Paints background @color/md_elegance_green with a Theme that also Paints a background (inferred Theme is @android:style/Theme_black_notitlebar_fullscreen)

The image illustrates the moment of the event:

I did some research but I did not understand very well. What does it mean overdraw? How should I do the treatment so that no more appears this Warning?

  • In the manifest theme,xml points to a theme while the layout color says another. Just a warning that there might be an overdraw - overwrite a color that has already been applied. Remove the line "android:background="@color..." that Warning will no longer appear.

  • @Reginaldorigo but I really want this layout to have a different background than the main theme. What is your suggestion regarding this?

  • Set this color in the theme.

  • @Pabloalmeida but I want the background color of this layout to be different from the theme. Understand?!

  • @seamusd So you should set a different theme for this layout. Themes may have other themes as parent, inheriting all of its features. Then you overlay the background. See Hugo’s response.

declares your theme in the archive: res/values/Styles.xml

<style name="MeuTema" parent="android:Theme">
    <item name="android:background">@color/md_elegance_green</item>
</style>

And uses this theme in Manifest.xml

android:theme="@style/MeuTema"

// EDIT

Parent="android:Theme" you put a top theme. In your case I believe it would be Theme_black_notitlebar_fullscreen
