[Android Themes] ZduneX25:
Hi guys it's time to share some of my tips with all themers :p

1) transparent/custom settings - from meziu and miui

a) transparent

open themes.xml with a good text editor

<style name="Theme" parent="@android:style/Theme">
<item name="android:colorBackground">@android:color/transparent</item>
<item name="android:windowBackground">@drawable/background_own</item>
<item name="android:windowShowWallpaper">true</item>
</style>

Now you have to fix blank screen in video-camera and small popups:

<style name="Theme.NoTitleBar" parent="@android:style/Theme">
<item name="android:windowShowWallpaper">false</item>
</style>

<style name="Theme.Black" parent="@android:style/Theme">
<item name="android:colorBackground">@android:color/black</item>
<item name="android:windowBackground">@drawable/background_own</item>
<item name="android:windowShowWallpaper">false</item>
</style>

<style name="Theme.Light" parent="@android:style/Theme">
<item name="android:windowShowWallpaper">false</item>
</style>

<style name="Theme.Translucent" parent="@android:style/Theme">
<item name="android:windowShowWallpaper">false</item>
</style>

<style name="Theme.NoDisplay" parent="@android:style/Theme">
<item name="android:windowShowWallpaper">false</item>
</style>

<style name="Theme.Panel" parent="@android:style/Theme">
<item name="android:windowShowWallpaper">false</item>
</style>

It's time to fix email, cos it looks weird with transparent bg:

themes.xml:

<style name="ThemeNoTitleBar.Email" parent="@android:style/Theme.NoTitleBar">
<item name="android:colorBackground">@android:color/black</item>
<item name="android:windowBackground">@android:color/black</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowContentOverlay">@null</item>
</style>

com_android_email.xml:

<resource-redirections>
<item name="style/ThemeNoTitleBar">@style/ThemeNoTitleBar.Email</item>
</resource-redirections>

Finally we should fix youtube, cos nobody likes transparent bg during watching video clips in full screen mode :p

themes.xml:

<style name="Theme.Youtube" parent="@android:style/Theme">
<item name="android:windowBackground">@android:color/black</item>
</style>

com_google_android_youtube.xml:

<resource-redirections>
<item name="style/Theme">@style/Theme.Youtube</item>
</resource-redirections>

b) custom

<style name="Theme" parent="@android:style/Theme">
<item name="android:colorBackground">@android:color/transparent</item>
<item name="android:windowBackground">@drawable/background_own</item>
</style>

Nothing else needs to be fixed

2) description color - also known from miui (orange) and meizu (blue)

open colors.xml with a good text editor

<resources>
<color name="dim_foreground_dark">#ff_your_color</color>

<item name="android:textSize">21.0sp</item>
<item name="android:textStyle">normal</item>
<item name="android:textColor">#ffffffff</item>
</style>

4) ics blue popup title

open themes.xml with a good text editor
