items not showing in mvxlistview

it fixes the issue The DataContext for your person list item is a Person - so your SelectDogCommand needs to be part of the Person class - e.g. something like:

public class Person
{
    private string _name;
    private List<Dog> _hasDogs;

    public List<Dog> HasDogs
    {
      get { return _hasDogs; }
      set { _hasDogs = value; }
    }

    public string Name
    {
      get { return _name; }
      set { _name = value; }
    }

    private Cirrious.MvvmCross.ViewModels.MvxCommand<Dog> _selectDog;
    public System.Windows.Input.ICommand SelectDogCommand
    {
        get
        {
            _selectDog = _selectDog ?? new Cirrious.MvvmCross.ViewModels.MvxCommand<Dog>(dog => _parent.SelectDog(dog));
            return _selectDog;
        }
    }

    private FirstViewModel _parent;
    public Person(FirstViewModel parent)
    {
        _parent = parent;
    }
}

Any of those help When reusing a list item, the binding will set the DataContext again, and this will cause the bindings to be reevaluated.

To fix the issue you can do After much help from @Cheesebaron and @Stuart I have found that if you use MvxSpinner or MvxAutoComplete in an ItemTemplate inside an MvxItemList, then anything in the hierarchy above and including the MvxItemlist cannot have android:layout_height="wrap_content". The reason is that the Android OS has to draw things more than once if it has to determine their height dynamically. All the redraws get things confused in the binding. If you set everything to a fixed height, everything works fine. To fix the above problem, the Markup for the MvxItemView above should be

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical">
        <MvxListView
            android:layout_width="fill_parent"
            android:layout_height="300dp"
            local:MvxBind="ItemsSource ShipmentLots.Lots"
            local:MvxItemTemplate="@layout/inventorylotview" />
        <ImageButton
            android:src="@drawable/ic_action_new"
            android:layout_width="60dp"
            android:layout_height="60dp"
            android:layout_gravity="center"
            local:MvxBind="Click NewLot_Clicked"
            android:id="@+id/btnLotNew" />
    </LinearLayout>

it should still fix some issue Try the following:
1) If you want to remove divider line use this code :

android:divider="@null"

android:divider="@android:color/transparent"
android:dividerHeight="5dp"

this one helps. The property to load a collection is ItemsSource, not ItemSource. Replace this:

local:MvxBind="ItemSource Reminders"

local:MvxBind="ItemsSource Reminders"
