CursorAdapter 's ViewBinder lifecycle?

Can someone help me understand SimpleCursorAdapter.ViewBind开发者_C百科er lifecycle in terms of methods: setViewValue, bindView when are they called? Are instances re-used? Any source to understand all of it?

I basically have a ScrollView that that uses setViewValue to populate items but it doesn't refresh the view value even when setViewValue is called again and again.

bindView is called first and later setViewValue.
