如何从 ImageView 列表中动态获取 imageview 并将 imageview 放置到 Z6C666B7F9E6BE3A848F2F 变量中

Question

If I have an array/list full of imageviews- List<ImageView> iv; where I dynamically add a few pics/icons/images, and I have a variable from type imageview called IV and a number between the lengths of

0 to the length of the list-1,

how can I take the imageview from the list/array and set it to IV which is our variable which is imageview type?

this is what I tried: IV=(iv.get(num)); but nothing seems to happen as in the image in our variable imageview doesn't change

doing this all dynamically using java, no xml.

Answer 1

You can use this. Make sure to check for null.

IV.setImageDrawable(iv.get(num).getDrawable());
