Answer 2

I had trouble with this control as well and Jim's example helped a lot. This answer warns against binding Text and I think that has some merit purely because for me the control was half working. When binding to Text the list view would appear but I could never bind SelectedObject or PartialText. I noticed I was receiving the following bind error:
Error - autoComplete is null in MvxAutoCompleteTextViewPartialTextTargetBinding
The simple fix for me was to change
<MvxAutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
... />
To
<Mvx.MvxAutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
... />
