Android custom filter works great in vertical mode but doesn't filter in horizontal mode

My custom filter and adapter for an autocompletetextview works great when the app is vertical but in horizontal mode the spinner provides a list that doesn't change when one types in text. When you click done on t开发者_如何学JAVAhe softkeyboard, the vertical filter works perfectly. My question is, how do you disable the spinner that appears above the softkeyboard and below the textview?
