Java Import Error "the Type Android.widget.Filter.FilterResults Is Not Visible"

This question was already asked: the type android.widget.Filter.FilterResults is not visible But there was no clear answer, and now I'm getting the same problem. In that discussion

Solution 1:

Coming back to this to mark it as answered, from my previous comment on the original question:

Eclipse automatically adds that extra unneeded "import android.widget.Filter.FilterResults;" after "import android.widget.Filter". It's enough to have "import android.widget.Filter", so just comment out or delete the second import for Filter.FilterResults. Once I did that there were no more errors and all was working as expected.
