android - Change a ListView Item's Height based off it's location on the screen -

-

i'm trying make listview size of items in list view enlarged scroll up. have been looking ways buti'm having trouble finding how modify listview's scroll.

thanks help.

so after working @ while made discoveries. resizing size of each item computationaly rediculousely expensive. don't, once.

this lead new approach. instead resize things inside view. has same effect drastically faster.

this can done creating custom listitemview extends listview , overriding drawchild method.

hope helps tries similar.
