I call setChecked directly, because my "checkbox" tracking is in the same layout (although it's not a checkbox) To track selected items (for getView to do the right thing during scrolling, and to know what items user actions apply to), I'm using a LongSparseArray... Don't think it matters much (except ListView tracks checked items by position, whereas I prefer "stable" database IDs). I'm not using any choice modes inside ListView, because I also have an ActionMode UI implementation for Android 2.*, and it's abstracted away from the actual list...

So for example, you can use android:actionBarStyle=... when running on 2.*... and I expect android:attr_activated is the same way. -- K > > Regards, > Miha. > -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
