Answer 1

I assume you mean the issue of getView requesting the same view several times.

ListView does this because it needs to get measurements for the views for different reasons (scrollbar size, layout, etc)

This issue can usually be avoided by not using the "wrap_content" property on your listview.

Other than that, using getView to determine if a view has been displayed is simply a bad idea. ListView has many optimizations that mess with the order getView is called on for each row, so there is no way to know what will happen and your app will start showing odd behavior.

Try to avoid any relationship between the view and the data other than the concept of view as a display of that data.

Instead, have some worker thread or event listener in your listactivity watch the list for which items in the list have been displayed to the user, update the data, and call dataSetChanged on your adaptor.
