Android OneBusAway - How do I change colors?

Question

I'm not an android develop at all but I've been tasked with updating colors and styles for OneBusAway . Nothing fancy is required. Examples are changing the header area for green to purple or something like make the default grey background color a darker grey color. I figure that I should be able to open the code, change some hex colors, build and be done.

This should all be really simple but I cannot find where the actual colors get set.

For example, take a look at the code below:

<LinearLayout
            android:id="@+id/stop_info"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:background="@drawable/ab_stacked_solid_busbot"
            android:visibility="gone">

I want to change the background color. So, I search for ab_stacked_solid_busbot which leads me to the following:

public static final int ab_stacked_solid_busbot=0x7f020002;

This does not at all look like a style to me. However, it could potentially be a hex or RBA value but can't get it to match the existing app colors.

In styles.xml, I can find the following:

<style name="HeaderItem">
    <item name="android:background">@drawable/ab_stacked_solid_busbot</item>
    <item name="android:padding">4dp</item>
</style>

This still seems like there is a pointer to a style class somewhere with an atual color attached to it.

Can anyone point me in the direction of where I can make these simple color changes.

Answer 1

I believe that line you found is from the generated R.java file. That is an internal id used by the OS to find the drawable image. Take a look in your drawable folders and you should find an image or xml named ab_stacked_solid_busbot . You will need to modify the xml or in your image editor of choice based on the type.
