Is there a simple way to have text be able to have a black outline? I have textviews that will be different colors, but some of the colors don't show up on my background so well, so I was wondering if there's an easy way to get a black outline or something else that will do the job? I'd prefer not to have to create a custom view and make a canvas and such.
You can put a shadow behind the text, which can often help readability. Try experimenting with 50% translucent black shadows on your green text. Details on how to do this are over here: Android - shadow on text?
To really add a stroke around the text, you need to do something a bit more involved, like this: How do you draw text with a border on a MapView in Android?
outline effect can be achieved using shadow in TextView:
android:shadowColor="#000000" android:shadowDx="1.5" android:shadowDy="1.3" android:shadowRadius="1.6" android:text="CCC" android:textAllCaps="true" android:textColor="@android:color/white"
