Question

I occur a problem when develop a application on android.

There have two image which can be download from server in a list item, it will show one image and will show another image when user select or click this item .
if I try to download another image from server when user click it,the user will never have time to see it, for this time is shorter than download image form server,
so i want to download two of them,and when I click it again,the app can invoke another image from local.

but I do not know how to invoke this image ?

Any suggestion will be appreciate.

thx

Answer 1

put selector images on the drawable resource folder. if you download it from server then it will reduce your apps performance. check this answer of mine.
