Listview behaves in a different way . it tries to recycle views if it can .
>From your code you are not recycling views , you should try to use
If(convertview ==null)
{
create new view
}
else
{
map and use it
}
Will give you some hint
1) put some log statement in get view and check how many times its called
and what position
from that you can figure out whats happening.
Also google for some examples on customlistview which will give you some
idea.
