Xamarin Autocomplete view: Display dropdown even when there is no text

I am implementing an autocomplete view in my mobile app that i am developing using Xamarin.

I have set threshold to 1 and set the focus to autocomplete view in onCreate event of activity.

autoCompleteView.FocusChange += delegate(object sender, View.FocusChangeEventArgs args)
{
    if (args.HasFocus)
    {
        autoCompleteView.ShowDropDown();
    } 
};

It displays the dropdown with all the suggestions when my app is loaded. Whenever i type text, it filters based on condition and everything is working fine. But when i clear all the text in the autocomplete view, the dropdown is closed. But i want to display the dropdown with all the suggestions.

Also whenever i touch/click the autocomplete view, the dropdown is closed. So i have added the below code to display the dropdown, but there is a flicker(dropdown is closed and is opened again). 

autoCompleteView.Click += delegate(object sender, EventArgs args) {
    autoCompleteView.ShowDropDown ();
};

Thanks in advance.

  1. You can call autoCompleteView.ShowDropDown(); in you OnCreate (independant of focus), this way the app loads with the dropdown showing.

Also whenever i touch/click the autocomplete view, the dropdown is closed. So i have added the below code to display the dropdown, but there is a flicker(dropdown is closed and is opened again).

  1. Subscribe to the TextChanged event and call autoCompleteView.ShowDropDown(); whenever the text in the EditText is String.Empty.
