Android - set layout background programmatically

Question

I have noticed that the setBackground method for the RelativeLayout object is targeted for API 16 (Android 4.1) and higher, but my application has the targ

Answer 1

It depends. If you want to set a color as the background, use setBackgroundColor(). For a Drawable, you can use the now deprecated method setBackgroundDrawable() for APIs below 16, and setBackground() for API 16 devices. You can also use setBackgroundResource() for setting a resource as the background.

Note that while a lot of methods are marked as deprecated, I'm yet to come across one that has actually been removed. So while you could use the deprecated method even in API 16, I'd recommend setting your target API to 16 and using an if else to switch between the methods, depending on the API version the device is running.
