Set opacity for TextView

I have a TextView, and I wonder if there is a way to set alpha (opacity) for both text and image in a TextView programmatically. I found 'alpha' property in TextView properties, it affects to text of the TextView but will it affect to image in the TextView too? How do I do it programmatically?

your_variable_name.setALpha(0f);

f = float

0f means 0%

1f means 100%

0.8f means 80%

You can use setAlpha() in ImageViews also.

If you want to smooth the process(use an animation) : 

your_variable_name.animate().alpha(0f).setDuration(300);

300 is millis that means 1000 = 1 sec

You can wrap your views in a ViewGroup (FrameLayout,RelativeLayout ...) and call viewGroup.setAlpha(yourValue)
