I am having the same problem. In my case it only happens if I specify my own layout using setContentView in onCreate() of my ListActivity. If i use the standard layout i get correct number of calls to getView.
The thing is that if I have 5 items in my list i suspect the first 5 calls to getView to have convertView=null each time. But its not. First time its null, then the next 5 calls have the same convertView as the previous call and then 5 more calls where the convertView is null. So the first 6 calls to getView only results in changing the first element 5 times more than whats necessary. After the 5 first calls the convertView is null and the rest of the items in the list are filled out correctly. But when i scroll down the list, we have 10 more calls again. Does anybody have an idea whats wrong? Or how it can be avoided? I have no weights in my layout at all. Its just a simple textView with a status message and a listView. -Ola On Wed, Jul 15, 2009 at 4:05 PM, Streets Of Boston <[email protected]>wrote: > > I'm not a google engineer, so i don't know the answer, but i have a > theory why this may happen. > > In your layouts, do you use 'weights' (weightsum and layoutweight)? > If i remember correctly, if you use these attributes, layout-code is > called twice. > If the layout-code for a list-view includes the 'getView' then this > would explain it being called 4 times for 2 child views. > > On Jul 15, 2:40 am, Mika <[email protected]> wrote: > > Hi, > > > > I'm having the same problem.
