I got a WebView that load an HTML file with a text. The problem is that the color inside the html and outside isn't the same. Here is a screenshot:

The Activity With the WebView

The HTML FIle is:

<html dir="rtl">
<head>
    <title>About</title>
    <meta content="text/html; charset=UTF-8" http-equiv="content-type"/>

    <body bgcolor="#FFFFFF">
        <p>This is a Testpp</p>
        <p>See the problem.</p>
         <p>last test:</p>
    </body>
</html>

(If I remove the: bgcolor="#FFFFFF" color stays the same) Thanks!

The default background color of an Android layout? I think it's nothing, or in other words black. – Hornwort 24/1, 2013 at 17:41

Its black. Unless I'm misunderstanding your question. – Grotesquery 24/1, 2013 at 17:41

I edited the Question please look again. – Conjoined 24/1, 2013 at 19:14

the background color is based on your application theme, and is not a color at all, but rather a drawable. what were you trying to achieve once you found out what the color is? – Negation 24/1, 2013 at 21:37

i want to change the html color to the same color like outside the html. – Conjoined 25/1, 2013 at 8:46

The default background color for light theme is: #EEEEEE

Is almost white, but not completely.

It worked for me, hope its work for you.

UPDATE: In new versions you could be looking for #FAFAFA

It's the #EEEEEE still in android studio latest version. Thumbs up for this answer, thank you! – Mechellemechlin 15/3, 2016 at 11:56

I have found my self that in later API version it changes, would you be so kind to check if it any difference between 21 and below please? Maybe I did something wrong with my project – Dessalines 15/3, 2016 at 21:24

#FAFAFA +1 for me, emulator API 25, Theme.AppCompat.Light.NoActionBar – Allot 20/12, 2018 at 22:43

Thank you! May I ask where you can find this information, just in case it changes in the future? – Cultural 28/11, 2020 at 4:45

@Cultural is either an image editing tool or is it a source code – Dessalines 28/11, 2020 at 17:53

You can use your theme's default background color by referencing:

?android:colorBackground

android:background="?android:colorBackground" Works great! Any drawbacks with this solution? – Pedometer 13/4, 2018 at 14:43

To change your background (if this is in fact what you are looking to do):

in styles.xml

<style name = "MyDefaultStyle" parent = "@android:style/Theme">
    <item name = "android:windowBackground">@drawable/default_drawable_bg</item>
</style>

and in your manifest

<application
    android:name="MyApp"
    android:theme="@style/MyDefaultStyle" >

Go to Manifest

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/MyMaterialTheme.NoActionBar">

You see the Theme is MyMaterialTheme.NoActionBar

So go to res -> values -> styles

So for me the default is #FFFAFAFA

When i put the suggested colors #EEEEEE or #FAFAFA, it worked on some phones, and on other phones it was off, so that's what I found with trial and error

Default color is black.

If you use style, go to "values/styles.xml" and there is solution of you issue. Now you can check bg color. About themes and styles : http://developer.android.com/guide/topics/ui/themes.html

EDIT :

Layout background color changing - Setting background colour of Android layout element

EDIT 2:

If in styles.xml is @android:style/Theme.Light your bg color is white.

Thanks, but the styles.xml just saying which them is it(default:Theme.Light and API14:Theme.Holo.Light.DarkActionBar) and i want to know which background color is in that themes.(it isn't black) thanks! – Conjoined 24/1, 2013 at 18:8

it was useful but didn't answered my question – Conjoined 24/1, 2013 at 18:18

repeat your question in one sentence : – Almsgiver 24/1, 2013 at 18:20

I want to know want is the background color in my app.I have no background color in the xml or the java code and in the styles.xml it's just says that the them is "android:Theme.Light". – Conjoined 24/1, 2013 at 18:24

So why when i do a WebView and show an HTML test file so it's more white then the layout background?(Edit: in "Theme.Holo.Light" it's white too?) – Conjoined 24/1, 2013 at 18:37
