I have implemented a couple of different adapters in my application. No matter which base class I use, I get very weird behavior in how the list calls it to create and bind its views.
I've tested this on 2.3.3, 2.3.6 and Kindle. This log is from an implementation of BaseAdapter, I put a debug-print in "getView". If convertView is null I inflate the view and print "created view". For every call to getView I print "binding View" when I set its values. The code on the end is an id string for the data I bind to the views. Everything display just as it should, but I get lots of unneccessary binds! This is what I get when I set the adapter to the listview: D/SLPA ( 4097): created View - android.widget.LinearLayout@405bf190 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 0 - to: A5D7W5U9.02 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 1 - to: ASQK89Q8.58 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 2 - to: ASQK89Q8.37 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 3 - to: AEURWHRA.02 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 4 - to: ASQK89Q8.44 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 5 - to: ASQK89Q8.51 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 6 - to: ASQK89Q8.10 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 7 - to: AWQHVP6A.11 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 0 - to: A5D7W5U9.02 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 1 - to: ASQK89Q8.58 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 2 - to: ASQK89Q8.37 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 3 - to: AEURWHRA.02 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 4 - to: ASQK89Q8.44 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 5 - to: ASQK89Q8.51 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 6 - to: ASQK89Q8.10 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 7 - to: AWQHVP6A.11 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405bf190 position: 0 - to: A5D7W5U9.02 D/SLPA ( 4097): created View - android.widget.LinearLayout@405ab368 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405ab368 position: 1 - to: ASQK89Q8.58 D/SLPA ( 4097): created View - android.widget.LinearLayout@405a85f8 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405a85f8 position: 2 - to: ASQK89Q8.37 D/SLPA ( 4097): created View - android.widget.LinearLayout@40548088 D/SLPA ( 4097): binding View - android.widget.LinearLayout@40548088 position: 3 - to: AEURWHRA.02 D/SLPA ( 4097): created View - android.widget.LinearLayout@405743e0 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405743e0 position: 4 - to: ASQK89Q8.44 D/SLPA ( 4097): created View - android.widget.LinearLayout@405877c0 D/SLPA ( 4097): binding View - android.widget.LinearLayout@405877c0 position: 5 - to: ASQK89Q8.51 Its not weird that users complain of sluggish UI if these things are going on!

Is there anyone who can shed some light on this, is it just something I have to live with, or have I made some stupid mistake? I have a hard time imagining anything I could have done wrong though, since the code is really minimal. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
