android - Listview weird reaction on Clicking -
i'm displaying listview custom adapter. each item of list view has photo (imageview) , (flipimageview) button , textview show number of likes. have populated listview 3 items. weird issue when click on button of second photo, there no response (no flipping of image , no change in number of likes). instead first photo button responds , number of likes of first photo got incremented. second weird issue that, first item of listview isn't populated (an imageview lies blank while imageview of other list items inflate fully). when scroll , come first item, gets inflated fully. here adapter code, xml file of each list item, , listview itself. how solve these issues?

i remove these final declarations. populating them value of first item:
final eachpost post = posts.get(pos); final int finalpos = pos; final string han = post.gethandle(); final string imgurl = post.getdpbase64() to:
eachpost post = posts.get(pos); int finalpos = pos; string han = post.gethandle(); string imgurl = post.getdpbase64() you should see change in log.d("getdpurl",finalpos+response); when this. please let me know if doesn't solve problem.
there quite bit of info on over web.. here's one
