I'm having issues with color resources in Android, specifically using a transparent color.
Any time I use my transparent color from the colors resources, the background of the View shows up as a red gradient instead when previewed in the emulator (tested versions 1.6, 2.2 and 2.3 on AVDs) or on a device (DroidX w/ 2.3.4). The transparent color is displayed correctly (or rather, is not) in the preview mode in Eclipse.
As far as I can tell, this particular gradient isn't defined anywhere in my application. The title bar does use a red gradient from an xml shape resource, but it's completely different shades of red. There is also a very simple custom styles definition, but it only sets the window title background and text colors.
My color definition:
<color name="transparent">#0000</color> <!--Tried #00000000 as well // -->
An example View exhibiting the issue:
<Button
android:id="@+id/btn_login"
android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="5dp" android:layout_marginRight="10dp"
android:text="@string/ui_btn_login" android:textColor="@color/dark_grey"
android:background="@color/transparent"
android:drawableTop="@drawable/ic_login" android:drawablePadding="2dp" />
Results in the red gradient (when using the the color resource): http://i683.photobucket.com/albums/vv194/platinumF150/trans_resource.png
<Button
android:id="@+id/btn_login"
android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="5dp" android:layout_marginRight="10dp"
android:text="@string/ui_btn_login" android:textColor="@color/dark_grey"
android:background="#0000"
android:drawableTop="@drawable/ic_login" android:drawablePadding="2dp" />
Results in the correct display (when using the color code inline): http://i683.photobucket.com/albums/vv194/platinumF150/trans_color.png
However when I use android:background="@android:color/transparent" everything works normally...
I'm seeing this throughout my application, any view that uses @color/transparent gets a red gradient.
Obviously its not a huge deal to just use Android's transparent color everywhere, its just frustrating, and I'm sure there is a solution. I've never seen this issue before, but I've also never used too much transparency in an app.
Thanks for any thoughts or input you might have!
