[Galaxy Note GT-N7000 Themes and Apps] Kamy:
How to change Notification Background and Text Color on drop down panel: ​

Thanks majdini for his turorial but as my this theme is kinda associated together I have no choice to repeat first part for Notification background.

Notification Background color

A- First of all you need to make notification background independent (I call it) from systemui.apk so that the color can be changed by hex code in framework.

1- Go to SystemUI/smali/com/android/systemui/statusbar/phone/ folder and open PhoneStatusBar.smali and search for "-0x100". There will be two lines; change them from

const/high16 v15, -0x100

to

const/high16 v15,[COLOR="Red"] 0x0[/COLOR]

there are two lines for -0x100, change theme both

2- Now go to framework-res/res/values/ folder and open drawables.xml and look for this line:

<item type="drawable" name="notification_item_background_color">#ff000000</item>

I changed it to

<item type="drawable" name="notification_item_background_color">[COLOR="Red"]#ffececec[/COLOR]</item>

This was for the background part.

Notification Text color

B- So now we need to change the notification's text color that should be done in framework:

Just search for StatusBar in Style.xml and change it as you like. Following are my changes:

<style name="TextAppearance.StatusBar.Title" parent="@style/TextAppearance.StatusBar">
<item name="textStyle">bold</item>
</style>
<style name="TextAppearance.StatusBar.Icon" parent="@style/TextAppearance.StatusBar" />
<style name="TextAppearance.StatusBar.EventContent" parent="@style/TextAppearance.StatusBar.EventContent">
<item name="textSize">15.0dip</item>
<item name="textColor">[COLOR="Red"]#ff2e2e2e[/COLOR]</item>
</style>
<style name="TextAppearance.StatusBar.EventContent.Title" parent="@style/TextAppearance.StatusBar.EventContent.Title">
<item name="textSize">20.0dip</item>
<item name="textStyle">normal</item>
<item name="textColor">#[COLOR="red"]#ff000000[/COLOR]</item>
</style>
<style name="Theme.WithActionBar" parent="@style/Theme">
<item name="windowActionBar">true</item>

The first #ff2e2e2e is for subtext's color (second row of notification)

<style name="TextAppearance.StatusBar.Ticker" parent="@style/TextAppearance.StatusBar" />
<style name="TextAppearance.StatusBar.EventContent.Line2" parent="@style/TextAppearance.StatusBar.EventContent">
<item name="textSize">@dimen/notification_subtext_size</item>
</style>
<style name="TextAppearance.StatusBar.EventContent.Info" parent="@style/TextAppearance.StatusBar.EventContent">
<item name="textSize">@dimen/notification_subtext_size</item>
<item name="textColor">[COLOR="red"]#ff2e2e2e[/COLOR]</item>
</style>
<style name="TextAppearance.StatusBar.EventContent.Time" parent="@style/TextAppearance.StatusBar.EventContent.Time">
<item name="textSize">15.0dip</item>
<item name="textStyle">normal</item>
<item name="textColor">[COLOR="Red"]#ff000000[/COLOR]</item>
</style>
<style name="TextAppearance.StatusBar.EventContent.Emphasis" parent="@style/TextAppearance.StatusBar.EventContent">
<item name="textColor">#[COLOR="red"]#ff2e2e2e[/COLOR]</item>
</style>
<style name="TextAppearance.Small.CalendarViewWeekDayView" parent="@style/TextAppearance.Small">
<item name="textStyle">bold</item>

<style name="TextAppearance.DeviceDefault.StatusBar.EventContent.Title" parent="@style/TextAppearance.StatusBar.EventContent.Title">
<item name="textSize">20.0dip</item>
<item name="textStyle">normal</item>
<item name="textColor">#[COLOR="red"]#ff000000[/COLOR]</item>

So for these changes would result in this theme (only notification part)
