Android and setting alpha for (image) view alpha

Question

Is there really no XML attribute counterpart to setAlpha(int)?

If not, what alternatives are there?

Answer 1

I am not sure about the XML but you can do it by code in the following way.

ImageView myImageView = new ImageView(this);
myImageView.setAlpha(xxx);

In pre-API 11:

• range is from 0 to 255 (inclusive), 0 being transparent and 255 being opaque.

In API 11+:

• range is from 0f to 1f (inclusive), 0f being transparent and 1f being opaque.
